7 Control methods

7.1 Methods of incoming and production operational quality control are established in the technological documentation.

7.2 Methods for quality control of products during acceptance control and acceptance tests

7.2.1 The geometric dimensions of the products, as well as the straightness of the edges, are determined using the methods established in GOST 26433.0 for the part being tested and by measuring the largest gap using feeler gauges according to ND.

7.2.2 The maximum deviations from the nominal dimensions of the gaps under the overlay are checked using a set of feeler gauges or a ruler in accordance with GOST 427.

7.2.3 The sag in the mating of adjacent parts lying in the same plane is determined with a feeler gauge as the distance from the edge of a ruler according to GOST 427, applied to the upper mating surface, to the lower surface.

7.2.4 The appearance, quality of welds, color and quality of finishing of products are assessed visually by comparison with standard samples approved in the prescribed manner. Surface defects visible to the naked eye from a distance of 1.5 m in natural light of at least 300 lux are not allowed.

7.2.5 Adhesion (adhesion strength of paint and varnish coatings to the metal surface) is determined by the method of lattice cuts according to GOST 15140.

7.2.6 The tightness and correct installation of sealing gaskets, door devices, fasteners and other parts, the color and absence of cracks in welded joints, markings and packaging are checked visually.

To determine the tightness of the sealing gaskets, compare the dimensions of the gaps in the recesses and the degree of compression of the gaskets, which should be at least 1/5 of the height of the uncompressed gasket. Measurements are made with a caliper or ruler according to GOST 427.

The tightness of the sealing gaskets with closed sheets can be determined by the presence of a continuous trace left by a coloring substance (for example, colored chalk), previously applied to the surface of the gaskets and easily removed after testing.

7.2.7 The operation of door hinges is checked by opening and closing the door elements of the product ten times. If deviations in the operation of door devices are detected, they are adjusted and rechecked.

7.3 Methods of control during periodic testing

7.3.1 The reduced heat transfer resistance is determined according to GOST 26602.1.

7.3.2 Air and water permeability are determined according to GOST 26602.2.

7.3.3 Sound insulation is determined according to GOST 26602.3.

7.3.4 Indicators of failure-free operation, resistance to static, dynamic, and shock loads are determined according to normative documents and methods approved in the prescribed manner.

When testing resistance to dynamic loads, the load that occurs when a door leaf is suddenly opened (for example, during a draft) is simulated at the moment the door leaf comes into contact with the slope of the doorway.

The test for impact resistance of a soft inelastic body is carried out with a three-time impact, for example, with a pear with a bottom diameter of (300 ± 5) mm and a mass of (30 ± 0.5) kg, from a drop height according to 5.3.5 into the central zone of the sample.

GOST regarding metal fire doors, requirements for them and operating features.

What are the requirements of GOST?

To protect production, personal property and other valuables from damage as a result of fire, as well as to maximize the localization of the fire itself, it is necessary to install special fire doors. They are capable of not only withstanding very high temperature, but also comply with all safety standards and requirements. Unfortunately, not all manufacturers approach their work responsibly, which means that in order to choose a truly high-quality product, you need to know exactly what features fire doors should have. This is exactly what will be discussed further.

In most cases, fire-resistant metal doors are installed for emergency exits. In accordance with the current GOST 31173-2003, they must have locks, but at the same time, they must open quite easily. GOST requires that metal fire doors be made in such a way that even a child can use them if necessary. Considering the fact that in the event of a fire door handles can become very hot and leave burns upon contact, GOST requires making a special button on the doors, or connecting the opening mechanism to the middle rod, maintaining the minimum force required for opening.

As for opening the door itself, for maximum convenience, safety and effective use, the doors should open towards the exit. This is how you can minimize the accumulation of a large number of people directly at the exit.

Particular attention should be paid to the material used for finishing. First of all, it should not be afraid of direct exposure to fire, it should not melt, much less ignite.

If at least one of the above nuances is not observed, this can have an extremely negative impact on people’s lives and health. If all the norms and requirements prescribed by GOST 31173-2003 are fully complied with, this will not only prevent the spread of fire, but also quite possibly save someone’s life.

Related article: Outdoor porch cover. We select suitable materials.

If you pay attention to the requirements for fire safety, and, as a consequence, for fire doors, various enterprises, then they are, in fact, almost the same type.

first of all, the door must withstand exposure to direct fire for as long as possible, but not melt or deform;
prevent the spread of smoke and carbon monoxide;
easy to open.

Production Features

In accordance with GOST 31173-2003, for thermal insulation and design of fire doors, it is allowed to use only those materials that are not susceptible to fire, even when exposed to direct fire. Similar requirements apply to consumables. Among other things, handles, fittings, locks and other elements must have minimal thermal conductivity. Only in this case will they maintain a sufficiently low external temperature and will not cause a burn upon contact with the skin. Decorative finishing is simply missing.

Concerning exterior finishing, then only those compositions and paints and varnishes that are fire-resistant can be used, due to which the door provides additional protection against fire.

Based on the above requirements, not all manufacturers have a license allowing the production of metal fire doors. The main condition for obtaining it is the presence of special equipment capable of producing products of appropriate quality.

Where are fire doors used?

Despite the fact that the production of fire doors requires the use of specialized materials with fire-resistant properties, the cost of the products themselves is quite reasonable.

As a rule, the main objects where such doors can or should be installed are production workshops and premises, service stations, private houses, warehouses, as well as special-purpose premises.

In fact, this list can be continued almost indefinitely; the main thing remains that the fire door is installed in those rooms that need to be protected from fire.

Design features of fire doors

Fire door design

In accordance with GOST 31173-2003, there are 2 types of features that you should pay special attention to:

First of all, we are talking about the availability of documents that allow a particular organization to engage in the production of metal fire doors, that is, the presence of a license. Among other things, each door must have an appropriate quality certificate and an individual passport, which indicates the main characteristics of the product, permissible temperature conditions and other parameters.

Related article: Infrared heated floor under tiles: do-it-yourself installation

If you study GOST 31173-2003 in more detail, you will notice that each fire door must have certain visual features. Let's look at them in more detail:

Mandatory design feature of a fire door	Note
No through holes or cracks	It's quite easy to check. It is possible to provide a light difference in two adjacent rooms. If gaps are visible, it means that the door has cracks and its quality no longer corresponds to what it should be in accordance with GOST
You should pay attention to the seal that runs along the perimeter between the frame and the metal door leaf	The seal should not even have small cracks, and to the touch be as elastic as possible
The softness of the closer plays an important role	for the most efficient, safe and comfortable use, the closer should move quite smoothly, but not require additional effort to operate
Pay attention to the awnings	As practice shows, many companies install awnings, but completely forget that the new product does not always contain a lubricant. Among other things, taking into account the specifics of the metal door itself, the lubricant used for the hinges must also have fire-resistant characteristics and properties, that is, withstand higher temperatures
Locking mechanism	Even light snacking in the castle is strictly prohibited. It should work as smoothly as possible and not require great effort when opening and closing. Otherwise, this can lead to extremely unpleasant consequences.

What is GOST R 53307-2009?

GOST R 53307-2009 is used when testing metal fire doors. It is this that guarantees that the product is of high quality and can save not only property, but also human life from fire.

Those products that have successfully passed the tests and received the appropriate certificate have some important features, such as the highest fire resistance, which allows these metal doors to be installed in offices, private homes, and large enterprises. Among other things, in accordance with GOST R 53307-2009, all products have the following characteristics.

Sections of the article:

In order for steel doors to meet a certain standard, it was developed normative base for these products. For metal doors, GOST standardizes the dimensions, type of hinges, optimal properties and characteristics. These requirements are contained in document number 31173-2003. Technical conditions and standards for steel door blocks were developed at the Certification Center, as well as by the Design Bureau. Entered into force on March 1, 2004.

Basic requirements according to GOST 31173-2003

This standard and requirements apply to all metal door structures for all types of buildings. This document described the most important parameters that door manufacturers operating in the Russian Federation must comply with. The only doors that are not covered in this regulatory documentation are highly secure structures and special-purpose products.

According to regulatory requirements, the door leaf must be a structure made of a metal profile and sheet metal, connected by welding. The standard allows the use of both straight and bent profiles. All corner connections can be performed using welding or other technologies (provided that the strength of the structure is maintained).

also in technical conditions information on the door frame is provided - manufacturers are recommended to make this element from bent profile pipes or a bent profile. As for the dimensions, the profile should be no thinner than 1.5 mm, the cross-section of the pipe should be at least 40x50 mm.

In addition to the profiles on which the base is created, the door block must also be reinforced with special elements. The standard provides at least two vertical and horizontal stiffeners. Reinforcement through inclined profiles is also possible. Horizontal stiffeners should be located in the area of anti-removal systems or in the hinge area.

GOST recommends installing two or more sealing circuits on external metal doors. They must be installed strictly without gaps, and the sealing material must be selected based on the climatic zone and possible atmospheric influences.

All requirements specified in this regulatory documentation can only be used for door structures of certain overall dimensions. So, the area of the canvas should be no more than 9 m2. The height of the opening leaf is less than 2200 mm, the width is up to 1200 mm. The standard weight of the block is no more than 250 kg.

Classification of doors according to standards

GOST 31173-2003 describes the classification of door structures. Thus, all door blocks according to their purpose are divided into internal or entrance and external.

In appearance and design, the standard divides steel doors into models with a closed frame, with door frame U-shaped type, as well as with a U-shaped box and with an additional threshold.

In addition, products are distinguished by the number of panels and the side of their opening. The standard provides for single-leaf structures, double-leaf ones with the same or different widths of the leaves, with one or more non-opening inserts. On the opening side, the door can open inward or outward.

There is also a difference in the number of sealing contours - these are doors with one contour or models with two or more contours.

A door block made of steel can have decorative finishing. Thus, the documents recommend several types of finishes. This is the canvas covering paint and varnish compositions or powder coating. GOST also allows the use different kinds artificial or natural leather, insulation, decorative materials based on films. Available in finishes based on wood materials– this is natural or synthetic veneer, solid wood. In addition, manufacturers can equip the canvas with glass or mirror materials. Combined finishing is also allowed.

GOST 31173 2003 divides metal doors into strength classes. So, there are three classes - M1, M2 and M3. The strength level is assessed by its resistance to different types of loads. They can be static or dynamic, shock and others.

Materials and components

All materials that modern manufacturers use to produce door structures must be manufactured in accordance with certain standards and conditions. So, the steel sheet should be as smooth and smooth surface. There should be no cracks or deformations in the metal. The standard allows for slight waviness - its maximum permissible size is no more than 0.5 mm.

All materials and components used in production must withstand various climatic conditions and atmospheric influences. The structural elements of the steel block must comply with GOST 380, 1050, 5632.

Seals must be installed on the canvas and the box. In this case, even minimal gaps are not allowed. This is one of the requirements of GOST 307778, in the text of which you can find other requirements for seals.

Hinges, locks, locking hardware

Characteristics, installation methods, as well as the location of locks and hinges on the door leaf must be described in the manufacturer’s working documentation. The parameters of locking mechanisms and hinges are influenced by the dimensions of the door leaf, weight, and conditions of use. All requirements for locks can be found in documents GOST 5089 and 538.

The hinges must be attached to the block and the canvas using welding technologies or using mechanical connections, but with the condition of maintaining strength.

To provide the metal door structure with the required level of protection, the standard recommends the use of locking mechanisms various systems– these can be cylinder, lever type locks and others.

Steel door units can also be equipped with various accessories such as closers, bolts, opening limiters, eyes and chains. Locks and hinges, no matter what type they are, should not interfere with the easy and reliable closure of the door.

Finishing

As for the type of finishing, the manufacturer must agree on the door covering and its quality with the buyer of the product in the sales contract. Quality is assessed based on provided and pre-approved samples. The choice of suitable finishing material depends on the operating conditions of the door block.

The main documents that regulate metal coatings, as well as the requirements for coatings based on varnishes and paints are GOSTs 9.402, 9.401, 9.032.

According to the standard, the first layer should be a primer coating, then you can proceed to applying decorative and protective materials. More details on the requirements for finishing quality can be found in GOSTs 9.301 and 9.032.

Production of door linings made of metal.

If in finishing works If wood or wood-based materials are used, then manufacturers are guided by GOST 2140. According to it, the surface roughness should be no more than 60 microns. Wood moisture level is no more than 8-12%.

Sound insulation requirements

Sound insulation parameters must be established in design documents. The level itself is established during testing in special centers. According to GOST 31173, the door block must be soundproofed to levels of at least 20 dB.

The standard distinguishes three classes according to the level of sound insulation - for example, the first class has sound absorption rates from 20 to 25 dB, the second class - from 25-31 dB, the third class - 32 and higher.

GOST on thermal insulation

All metal blocks are divided into three classes. Classification is made according to heat transfer resistance. Thus, products of the first class have indicators of 1.0 m °C/W and higher, the second - 0.7-0.99 m °C/W, the third - 0.4 -0.69 m °C/W.

In order for the unit to provide adequate thermal insulation characteristics, street doors must be equipped with at least two sealing circuits. More details about this are indicated in GOST 24698 81. It applies to wooden, but also to external metal doors.

Requirements for outdoor or outdoor steel blocks

Outdoor door units are described in GOST 24698. In terms of performance characteristics, these models must meet several important requirements.

Thus, these solutions must have high sound and thermal insulation characteristics. A seal must be installed on the frame and in the sash. Also, the surface and finish of the door leaf must have very high wear resistance in order to withstand atmospheric influences. Protective layer must reliably protect the metal from corrosion processes.

In addition, the door must withstand temperature changes and not deform. The document also states fire safety and strict adherence to geometric characteristics. It is necessary to have more serious locking devices than are provided for ordinary entrance doors to the apartment.

All these provisions and requirements must be fully complied with by manufacturers of metal door structures. The quality of the final product depends on whether the manufacturer strictly complies with GOST. The majority of all metal doors produced in Russia are truly high quality and fully comply with these requirements. The buyer receives a highly reliable and protected product.

Key words: door blocks, door leaf, frame, steel sheet

Metal doors are installed in residential, industrial and public premises. They are durable and reliable, and this is achieved by complying with GOST requirements that relate to the manufacture and installation of doors. It is this standard that ensures durability, safety metal sheets for various purposes.

Standards for the production and installation of metal doors

The production of doors from metal, as well as from other materials, is regulated by established and current standards, namely GOST. This code includes basic production rules, requirements for parameters and materials, as well as installation technologies for metal doors. Thanks to this, the structures are reliable, have a long service life and ensure human safety.

Any metal doors must comply with GOST requirements

The main document regulating the production of metal doors of various types is GOST 31173–2003. Additionally taken into account sanitary standards and rules (SNiP), which are a set of requirements for the quality and safety of products. These documents regulate the production of metal doors, and the installation of structures is carried out taking into account additional documentation, namely technological map, developed and presented by the manufacturer.

General provisions of GOST for metal doors

GOST 31173–2003 is used for metal door blocks equipped with locking devices and used in buildings and structures of various types. However, the document does not apply to special-purpose products, for example, bulletproof or fire-resistant options, as well as explosion-resistant models.

Doors that comply with GOST are reliable protection premises

The standard involves the classification of metal sheets according to the following criteria:

purpose, namely external or internal systems;
the design may have a box U-shaped or with a closed loop, as well as with a threshold;
the system can be made from one leaf, two identical ones or different canvases, with opening outwards or inwards;
number of circuits providing sealing - one or two;
the finishing of the canvas can be in the form of a painted surface, lining with leather and insulation, lining made of glass, wood or wood-tile structures;
sound insulation level - 1st class (up to 32 dB), 2nd class (26–31 dB) and 3rd class (20–25 dB);
degree of protection: regular, reinforced and security doors. In each case, there are locks of the appropriate strength level.

The regulatory document takes into account all the features of metal door systems. For example, seams and joints metal parts must be carried out by welding. The box can be made of a curved profile, but the thickness of this element must be from 1.5 mm. And also for door frame a box from a profile is appropriate rectangular shape, and its minimum cross-section is 40x50 mm.

The frame is an integral part of the door system

GOST includes not only mandatory requirements for the manufacture of metal doors, but also recommendations that allow you to create reliable products. For example, the standard recommends the use of horizontal and metal profiles gain. They are called middles and make the canvas durable and resistant to mechanical stress.

Inside the leaf, you can use a solid sheet of steel, which is an additional reinforcement for the door. A plate consisting of elements welded together is also an acceptable option. Weld in this case, it passes along reinforcement profiles, which ensures the strength of the final product. The internal additional sheet can be in the form of fibreboards or other solid sheet-type materials. These door components are used in the manufacture of door leaves different types, for example, entrance or insulated.

Insulated doors according to GOST

The design of insulated doors provides maximum protection of the room from heat loss through the leaf and prevents the penetration of cold through cracks. Such doors have a thermal insulation material in their structure, which is located between the outer and inner cladding.

Insulated doors are often external

The standard assumes the following features of the manufacture and installation of insulated doors:

thermal insulation is ensured by at least two sealing contours located around the perimeter of the entire vestibule;
all materials used for the manufacture of the canvas and the box must have a sanitary certificate on the safety of the structure;
paint and varnish compositions must have high adhesion to the surface of a metal door, and the finish should not peel off, creating cracks and promoting heat loss;
if the finishing is made of wood or particle boards, then such surfaces should not have cracks that could cause the canvas to blow through;
insulated door models, like any other, are mounted only in a prepared opening with smooth edges;
during installation, all gaps between the box and the wall are treated polyurethane foam and other structures that eliminate gaps;
materials used to create assembly seam, must be durable, safe, strong, and not subject to rotting.

Requirements for the production and installation of insulated systems require the creation of sealed seams and connections. This eliminates the possibility of heat loss from the room.

Steel fire doors

The production of fire doors made of steel is regulated by GOST R 57327–2016, which includes the basic requirements for this type of structure. This document applies to single- or double-leaf metal doors with or without glass up to 25%, fixed as fire barriers and having appropriate protective properties.

Fireproof fabrics are characterized by fire resistance and tightness

The fire resistance of systems is characterized by such indicators as E - loss of integrity of the fabric when exposed to heat, I - loss of heat-insulating qualities, S - loss of smoke and gas impermeability resulting from the action of fire. The flame resistance limit can range from 15 to 60 minutes.

The main GOST requirements for these structures, their production and installation are expressed as follows:

finished goods fire-fighting type withstand the number of openings/closings of at least 200,000;
Fire doors are always equipped with closers. For double-leaf structures, devices are also required to control the sequential closing of the leaves;
a door with a closer, open 90°, should close tightly in less than 5 s. The door can be opened with a force of no more than 100 N;
smoke-gas-tight systems always have a closed-type box with a threshold. If the roadway is located in the path of people moving disabilities, then the threshold should not be present;
For sealing, polymer gaskets are used, between which no gap is allowed. Thermal expansion gasket options prevent the spread of smoke and carbon dioxide;
installation involves the use of non-flammable sealants. Latches, locks and other structural elements are always made from fire-resistant structures, which is also important for filling canvases. If there is glass, it must be fire-resistant;
The service life of the finished structure is at least 10 years. In this case, the product should not sag, which is achieved correct installation and careful preparation of the opening.

Fire doors can have either one or two leaves

Fire-prevention fabrics can be supplemented with attachments, for example, video cameras, intercom elements. In this case, testing to determine their level of fire resistance is not required. It is worth considering that the fittings cannot contain sharp, strongly protruding parts.

External doors made of steel according to GOST

Metal sheets are a popular option for entrance doors. Such products are durable, resistant to climatic influences and other external factors. Their production is carried out in accordance with GOST 31173–2003, which includes the basic requirements for quality, production and installation.

Exterior doors should be as strong and durable as possible

According to the standard, the system can have fixed inserts of horizontal or vertical type. The maximum weight of moving blades should not exceed 200 kg.

Entrance systems are resistant to temperature changes and other climatic influences

External structures of a burglar-resistant or conventional type are often equipped with reinforced elements that do not allow the door to be opened illegally. The requirements for such parts, the manufacture of canvases and their installation are expressed as follows:

It is recommended to install anti-removal crossbars on the side of the leaf where the hinges are located. The pins are fixed by welding or pressing, and their number is determined by the working documentation and the type of door;
the box is equipped with “ears” on both sides. These parts serve to securely fasten the canvas in the opening. The “ears” are fixed to the box by welding;
the internal filling of the canvas consists of sound and heat insulating materials, which are placed tightly in the frame, eliminating the formation of voids;
The minimum sound insulation level is 20 dB. This is ensured by the use of modern, high-quality and high-tech materials;
Weld seams must be made smooth, without cracks or scaly surfaces. Uneven seams, deposits or burns are not allowed;
During installation, the quality of work is checked using a construction hydraulic level.

External doors protect the premises from cold, noise, and unauthorized access. Therefore, they must be of high quality, and safety must be ensured by the presence of anti-burglary devices, for example, vertical bolts.

Metal doors with glass

Entrance, vestibule or other doors made of steel can be equipped with glass. According to GOST requirements, such an insert should not occupy more than 25% of the entire sash area. This is due to safety requirements and allows us to ensure comfortable conditions in room.

Glass is often complemented with forged metal grilles

The basic requirements of the standards suggest that the insert must be made of tempered glass or triplex material that does not form fragments when damaged. This makes the doors safe when exposed to fire, impacts or other factors.

Standards ensuring the quality of glazed products require the following design features:

the connection between the glass and the door leaf is a sealed zone that ensures reliable fixation of the insert;
When installing the canvas and frame, the presence of cracks and gaps is not allowed, as condensation may form on the glass;
installation is carried out using wedges made of plastic or wood, and vertical deviations should not be more than 2 mm.

Glass doors are often complemented by a metal grille or forged insert. Thanks to this, the product acquires an aesthetic appearance and is burglar-resistant.

Parameters of metal doors according to GOST

The current standard imposes certain requirements for the dimensions of metal door systems. This is due to the fact that products must have optimal ratio size and weight necessary for comfortable operation and durability of the door.

Doors are varied not only in appearance, but also in size

During manufacturing, the following GOST standards regarding product parameters are taken into account:

the diagonals of the valves with an area of 1 m2 should have lengths with a difference of no more than 2 mm. If the area of the canvas is larger, then the difference in lengths cannot be more than 3 mm;
the edges of the canvas and frame are straight, and the deviation from this cannot be more than 1 mm per 1 m of length;
The box is fastened with anchor bolts, the cross-section of which is at least 10 mm;
the area of external or other metal doors does not exceed 9 m2. In this case, the recommended height of the sashes is 2200 mm, and the width is up to 1200 mm.

Requirements for fittings

During manufacture, metal doors are equipped with locking devices that meet the requirements of standards 5089 and 538. All hinges, locks, bolts and other parts are made of durable and refractory metal.

During production and installation, the following features are taken into account:

models weighing more than 200 kg or doors intended for hospitals and other public buildings, fixed to three overhead bearing hinges or parts that allow you to adjust the blade;
locks and other latches must provide a tight seal, careful pressure to the frame and seals;
doors of public premises are equipped with anti-panic devices, closers, smoke detectors and other devices that ensure quick opening of the system;
burglary-resistant or reinforced panels are equipped with multi-bar locking devices that have additional locking into horizontal frame profiles.

The protective properties of a metal door depend on the quality of the lock, handle, hinges, and armored linings on the lock. The type and parameters of these parts are determined before the fabric is manufactured.

GOST: marking and completeness of metal doors

Ready door systems must be supplied assembled, and the locking mechanisms are already installed on the canvas. This makes installation easier even with a non-professional approach, for example, if the buyer decides to install the structure himself.

Metal doors are installed using parts from the kit

Mandatory labeling involves marking each product with a label or inscription with a waterproof marker. The content includes the name of the manufacturer, as well as the brand of the door and the date of its production. The order number and a stamp indicating acceptance of the product by the quality control system must be present.

The finished kit includes instructions for using a metal door and a quality certificate. In these documents, the consumer can find recommendations for installing the element. The kit assumes the presence of a lock, handle, hinges and other parts specified by the manufacturer in the description of the door model or additionally ordered by the buyer.

The requirements of current standards apply to metal doors of various types. The application of these standards in practice allows us to obtain high-quality products and ensure correct installation.
