Guest standards for windows. GOST standards for plastic windows GOST standards for PVC construction deviations
It is a mistake to think that knowledge of state standards governing the manufacture and installation of plastic windows should be of interest only to manufacturers and installers of window structures made of plastic profiles.
Increased demand for glazing using PVC frames sometimes gives rise to unfair offers. Construction companies, of course, will not allow the installation of plastic windows, the manufacture of which did not comply with the current GOST, because they know that failure to comply with the current rules will lead to the refusal of the selection committee to issue permission to put the facility into operation.
For a private individual, knowledge of GOSTs regulating the production and installation rules of PVC windows will help control the ordered window structures at the design, manufacturing and installation stage. This is also important when replacing old window units in multi-story housing, but especially when building your own home. Compliance with state standards significantly extends the service life of window glazing and determines the warranty period for installation work, so if they are not followed, you have the right to warranty service.
A window can be installed correctly only if the technological standards for its manufacture have been met. A reliable manufacturer has certificates of product compliance with state standards.
Current GOST standards for window installation
The standards of the new GOST R 56926-2016 systematized and combined all GOSTs, SNiPs and technical standards in force as of November 1, 2016, while considering a PVC window as a structural element of a multi-story residential building. These standards do not apply to the construction of private housing.
The new state standard lists the current industry state standards that regulate the production and installation of plastic window units:
- characteristics of plastic window structures - GOST 30674-99;
- general requirements for windows and balcony blocks for buildings for various purposes - GOST 23166-99;
- Specifications for the production and installation of double-glazed windows construction purposes— GOST 24866-99;
- requirements for sound and heat insulation, ventilation of products - GOSTs 26602.2-99, 2602.1-99 and 26602.3-99;
- requirements for the characteristics of the profile, components and accessories (window sills, slopes, flashings, platbands, etc.) - GOST 30673-99;
- installation technology using vapor-permeable self-expanding tapes when making installation seams - GOST 52749-2007;
- technology for insulating assembly joints - GOST 30971-2012 replaces the outdated GOST 30971-2002.
Types of installation according to state standards
Types of installation are classified depending on the method of fastening the product into the opening. Correct installation requires only two types of fastening: using self-tapping screws directly through the plastic frame profile and using reinforcement if it is built into the model.
In the first case, you can even install the window correctly yourself, having a little experience and reading current instructions. The second method requires a more professional approach.
Installation flow chart
Each company's installation process sheets may differ, but the main sections must comply with standard technological instructions and include parameters of window units (window dimensions in width and height, profile parameters in mm), characteristics of double-glazed windows, organization and technology of installation, including diagrams of installation seams, quality control with permissible deviation limits, operating conditions, safety requirements.
TTK usually provides the following procedure for installing PVC windows in accordance with current standards:
- measurements;
- preparatory work;
- fastening the frame with one of 2 types;
- drain installation;
- window assembly;
- filling gaps;
- installation of a window sill.
Definition correct size window opening is 50% of the installation quality and guarantees a long service life of the window structure due to timely elimination of distortions. The size of the window is determined taking into account the installation gaps established by state standards.
After attaching the frame using one of the methods on special bars, fixing it with wedges and leveling it with special substrates, tighten the fasteners (anchors, self-tapping screws).
Requirements for installing a drainage system include foaming it and then checking the structure for compliance with geometry and strength. After installing the drain, the window block is assembled.
An important installation rule is to follow the technology for filling gaps in strict accordance with state standards, which provide for the following procedure:
- gluing vapor-proof waterproofing tape along the entire internal perimeter of the frame;
- treatment of external seams with PSUL membrane strip - self-expanding sealing tape;
- filling gaps with foam for different climate zones.
Insulation assembly seam connections must be made in accordance with the requirements of State Standard 30971-2012, which include 3-4 layers with various functions: heat and sound insulation, diffusion of moisture from the seam, vapor barrier.
If the junction seams are insulated correctly, the room will be reliably protected from the penetration of moisture, sounds, drafts, dust, and the double-glazed window from the formation of condensation, which in turn will significantly extend the service life of the products.
Installing the window sill is the final stage. In order to correctly install this part, it is necessary to take into account the requirements of the state standard for permissible penetration of walls, its slope and sealing of seams.
Warranty period for installation according to state standards
If you are thinking about how to install a PVC window, please note that an installation guarantee is issued only if all requirements of state standards are met. If you are not sure that you can handle this professional work, it is better to entrust it to specialists.
The long service life of glazing largely depends not only on the manufacturer. Proper operation also affects the service life of the product. Usually, after installation, operating instructions are provided, and serious companies offer their own versions of instructions for various models.
Installation of plastic windows in accordance with GOST and proper operation guarantees their long service without serious breakdowns for 50 years.
Windows are an important component of any construction process. At the stage of building construction, they are given attention in terms of optimal design and load. During the renovation process, owners of offices and residential premises independently regulate the location of windows, their height and dimensions, since GOST for windows 2002 does not provide specific absolute values. At the same time, there are a number of regulations and standards that are documented and must be observed by companies producing and installing wooden, plastic or aluminum profile windows (GOST takes into account the features and technical parameters in each case). Here are various classifications, window designations according to GOST, technical parameters, markings and specifications of windows and doors according to GOST, etc.
GOST 12506 81 for windows
If you prefer wooden windows, GOST will be useful to you. The standard defines window types. For example, according to the opening method they are distinguished:
- wooden windows opening inward (B);
- blind non-opening windows (D);
- outward opening windows (H).
According to GOST, wooden windows and doors have specific specifications and technical features depending on the type of room, its purpose and other parameters. From the document you will learn how wooden windows are classified and installed - GOST 12506 81 will give answers to everything current issues. This is especially important given the growing demand for such window designs. They are environmentally friendly, aesthetically attractive, natural and reliable.
GOST 23166 99 for plastic windows
The provisions of this standard apply to balcony door and window units made from metal alloys, wood, and plastics. They are intended for structures of various functional purposes. Thus, GOST covers metal, steel windows (gives classification and design features), etc. When choosing and installing a high-quality window, GOST 23166 99 can be very useful.
GOST for windows 21519 2003
This standard describes the basic requirements, features and standards for door and window structures, the production of which involves the use of aluminum profiles. The products are designed for use in buildings for various purposes. The document provides various classifications. So, based on design features profile according to GOST aluminum windows make:
- from a hollow profile (A);
- from a combined profile, the thermal insulation insert of which is filled with insulation (AKU);
- from a combined profile with an insert with thermal insulation properties (AK).
GOST 30971 2002 for plastic windows
It is generally accepted that the success of long-lasting and trouble-free operation of windows is half dependent on correct installation. In fact, competent installation can play an even more significant role, because mistakes can nullify even the most best characteristics window design. As practice confirms, GOST for plastic windows, which regulates their installation, is extremely important. It allows you to formalize the process and limit the freedom of manufacturers in choosing tools, methods and installation technologies. This minimizes the options for negligence, unjustified savings, use of unskilled labor, etc. As a result - quality windows will be installed correctly, which means they will last a very long time, guaranteeing only comfort and ease of operation. According to GOST, each installation company installs metal-plastic windows, observing the provisions internal instructions. This, in turn, must be approved by the local government office.
GOST 30674 99 for plastic windows
The provisions of this standard apply to window structures, as well as balcony door blocks, which are made from polyvinyl chloride profiles. Currently, there is a consistently high demand for PVC windows - GOST 30674 99 reflects all the main technical points. The standard contains classifications of products according to various criteria, as well as basic provisions working documentation- design and technological. In accordance with GOST, plastic windows must be manufactured within the permissible deviations given in the text of the document. For example, the limit value of deviation of nominal dimensions should not go beyond +2.00 –1.00 mm.
Nowadays, you can easily find the required GOST, and windows and doors manufactured and installed in accordance with it will retain their original performance characteristics for a long time. You can glean a lot of useful information from the standards: window specifications (GOST contains the necessary explanations), requirements for buildings of any purpose, etc.

6 Test methods
6.1 General provisions
6.1.1 Profiles after manufacturing and before acceptance tests must be kept at a temperature of (21±4)°C for at least 2 hours. Before periodic tests, as well as if the profiles were stored (transported) at a temperature different from test temperatures, before testing they are kept at a temperature of (21±4)°C for 24 hours.
6.1.2 Tests (preparation for tests) of profiles, unless otherwise indicated, are carried out at a temperature of (21±4)°C.
6.1.3 Selection of samples for testing is carried out in accordance with 5.4.2-5.4.4. Samples for periodic testing are selected from a batch of profiles that have passed acceptance tests.
6.1.4 During testing, the use of test equipment and measuring instruments not specified in this section is allowed if their use satisfies established requirements to measurement error and test conditions.
6.1.5 During acceptance tests, the inspection results are recorded in a journal in which the profile designation is indicated; type, mode and test result; batch number (date) of production and testing of samples; signature and surname of the tester. Storage of test results in electronic form is allowed.
6.2 Definition of markings
The markings and the presence of the protective film are checked visually, and the conditions for removing the film are checked manually. Control of markings and the presence of protective film can be carried out on the production line.
6.3 Determination of dimensions and shape
6.3.1 Measuring instruments:
Ruler according to GOST 427;
Verification plate according to GOST 10905.
When controlling the size and shape of profiles, they are guided by the requirements and.
6.3.2 The length of the profiles is measured in five measuring segments using a tape measure.
The test result is considered positive if each measurement result meets the requirements of 4.2.1.
6.3.3 Deviations from the profile shape are determined on three meter samples. The result of measuring each parameter is taken as the arithmetic mean of the measurement results of three samples. In this case, the value of each result must be within the tolerances established in 4.15.
6.3.3.1 Deviations from straightness and perpendicularity of the profile walls along the cross section of the boxes are measured with a feeler gauge, determining the largest gap between the profile surface and the side of the square (see Figures 1a, 1b).
To determine deviations from parallelism of the front walls of the profile along the cross section, two metal rulers are used, which are pressed with ribs one above the other perpendicular to the longitudinal axis of the sample (see Figure 1c). Measure the distances between the edges of the rulers with a caliper per 100 mm of length. Deviation from parallelism of the front walls is defined as the difference between the largest and smallest dimensions. Measurements are carried out at three points along the length of the sample. The measurement result for each sample is taken to be the value of the largest deviation.
Instead of metal rulers, it is allowed to use two 90° calibration squares.
6.3.3.2 To determine deviations from the straightness of the sides of the profile along the length, the sample is applied alternately with all outer surfaces to the surface plate and using a probe, measure the distance between the profile and the surface of the surface plate. The maximum value of this distance is taken as the deviation from straightness [Figure 1d].
Note - For testing, it is allowed to use the surface of any measuring instrument (for example, building level according to GOST 9416) with a flatness tolerance of at least the ninth degree of accuracy according to GOST 24643.
6.3.4 The deviation of the cross-sectional dimensions is determined on five sections of the profile 50-100 mm long. Dimensions are measured at each end of the segment with a caliper.
It is recommended to monitor deviations in the nominal dimensions of cross-sections of profiles using optical and other instruments that provide a measurement accuracy of at least 0.1 mm. In this case, the length of the segments is set in accordance with the technical characteristics of the testing equipment.
The arithmetic mean value of the measurement results is taken as the test result for each measurement parameter, and each result must not exceed the permissible maximum deviations.
6.3.5 The procedure for determining the quality of cutting profiles along lengths is established in the manufacturer’s technical documentation.
Δ a- deviation from straightness of the front wall along the cross section of the profile;
Δ b- deviation from perpendicularity of the outer walls of the profile of the boxes along the cross section;
Δ h- deviation from parallelism of the front walls of the profile along the cross section (Δ h=h 1 -h 2);
Δ c- deviation from straightness of the sides of the profile along the length
Figure 1 - Determination of profile shape deviations
6.4 Determination of the mass of 1 m of profile
6.4.1 Test (measurement) equipment:
Laboratory scales in accordance with GOST OIML R 76-1 for general purposes with a measurement error of no more than 0.1 g;
Metal ruler in accordance with GOST 427 or other measuring instrument providing a measurement error of 1 mm.
6.4.2 Testing and processing of results
Measure actual length L 1 and weigh the sample, determining its mass - M.
Weight of 1 m profile M, g, is calculated using the formula
M=mL/L 1, (1)
Where m- sample mass, g;
L- sample length equal to 1 m;
L 1 - actual sample length, m.
Results are rounded to the nearest 1 g.
The arithmetic mean of the test results of three samples is taken as the test result, and the value of each result must comply with the requirements of 4.2.2.
6.5 Determination of appearance indicators
Appearance profiles (color, gloss, surface quality according to 4.2.8) are determined visually by comparison with standard samples.
Tests are carried out on three samples with a length of at least 250 mm under uniform illumination of at least 300 lux, directed at an angle of 45° to the surface of parallel samples.
Samples are examined with the naked eye from a distance of 0.5-0.8 m; the direction of the line of sight should be perpendicular to the surface and axis of the sample.
The test result is considered satisfactory if each sample meets the established requirements.
6.6 Determination of changes in linear dimensions after thermal exposure
The change in linear dimensions after thermal exposure (thermal shrinkage) is carried out using the “by risks” method on three samples with a length of (220 ± 5) mm in the longitudinal direction with the following additions:
The distance between the marking template needles is (200±0.2) mm;
Marks are applied to the front surfaces of the sample;
The sample is placed on a glass plate coated with talc;
Thermal exposure temperature - (100±2)°С, time - (60±2) min.
Changes in the linear dimensions of each sample must not exceed the established values.
6.7 Determination of heat resistance
6.7.1 Test equipment and auxiliary devices:
Thermal cabinet ensuring temperature maintenance (150±2)°C;
Length meter with an error of no more than ±0.5 mm;
Glass plate;
6.7.2 Test procedure and evaluation of results
Tests are carried out on three samples with a length of (200 ± 2) mm.
The samples are laid horizontally on a glass plate, previously sprinkled with talc, and placed in a heating cabinet heated to a temperature of (150 ± 2) ° C for 30 minutes.
After thermostatting, the samples are cooled in air for 1 hour.
The test result is considered satisfactory if there is no damage on all surfaces of each sample (swells, bubbles, cavities, cracks, delaminations).
Note - A positive test result is an indirect confirmation of the suitability of the profile for the bending operation.
6.8 Determination of impact resistance
6.8.1 Test equipment and auxiliary devices:
A device (Figure 2), which includes a guide device mounted on a tripod and ensuring that the striker falls from a height of (1500±10) mm; steel striker weighing (1000±5) g with a hemispherical impact surface with a radius of (25±0.5) mm; steel supports fixed to a foundation (table) weighing at least 50 kg;
A freezer that maintains temperatures down to minus 25°C.
1 - sample; 2 - pipe with internal diameter(50+1) mm; 3 - striker; 4 - tripod; 5 - support; 6 - foundation
Figure 2 - Device for determining the impact resistance of profiles
6.8.2 Preparation for testing
Tests are carried out on ten samples with a length of (300 ± 5) mm.
Before testing, samples of profiles of types III and IV (Table 1, 4.5) are kept in a freezer at a temperature of minus (10±1)°C, and profiles of types I and II - minus (20±1)°C for at least 1 hour The profile must be positioned in such a way that the impact of the striker falls on the front wall, which is exposed to climatic influences (street side), in the middle of one of the chambers closer to the axis of the center of gravity of the cross section of the profile, indicated on the drawings of the profile sections. Tests are carried out no later than 10 s after removing the sample from the freezer.
6.8.3 Test procedure and evaluation of results
Raise the striker and, using a locking screw, set it at a height of 1500±10 mm from the profile surface. The striker is released, which falls freely onto the sample. The firing pin must be secured upon rebound (repeated impact is not permitted), then the firing pin is lifted and the sample is removed and inspected.
The sample is considered to have passed the test if, upon inspection, no cracks, damage, or delaminations are found on its surface. At the point of impact, dents on the surface of the sample are allowed. The test result is considered satisfactory if at least nine out of ten tested samples passed the tests.

Appendix A (informative) Terms and definitions
For the purposes of this standard, the following terms and corresponding definitions apply.
Profile system - a set (set) of PVC profiles and component elements combined into a complete structural system, documented in design documentation.
Profiles are parts of window blocks made by extrusion with specified shapes and cross-sectional dimensions.
Profile width is the largest dimension between the front outer and inner surfaces of the profile.
Profile height is the largest cross-sectional dimension of the profile in the direction perpendicular to the profile width.
The chamber is a closed internal cavity (system of cavities) of a PVC profile, located perpendicular to the direction of heat flow. The chamber may consist of a number of subchambers separated by partitions. Chambers and subchambers can perform various specified functions, for example, for installing reinforcement inserts or as self-ventilation channels.
Rebate is a part of the profile surface formed by the protrusion of one of its parts.
Clearance - the distance between the sash and the frame, established based on the conditions of normal functioning of locking window devices.
The narthex is the place where the sash connects with the frame bars (main narthex), with the impost (impost narthex) or with the sash (impostless, stulpovy narthex).
Overlap is a protrusion in the narthex assembly, formed by the protruding part of the frame (sash) and overlapping the sash (frame) by the size in the narthex under the overlay.
Reinforcing liner is a profile steel element installed in the internal chamber of the main profile to absorb operational loads.
A combination of profiles is a junction of mating profiles (for example, a frame profile - a sash profile with a glazing bead; an impost profile - a sash profile with a glazing bead; a sash profile with a bead and a glazing bead - a sash profile with a glazing bead).
The main profiles are the profiles of frames, sashes, imposts, and frames, which perform a strength function as an integral part of window and balcony door structures.
Additional profiles are profiles that do not perform a strength function as an integral part of window and balcony door structures.
Glazing beads (glass layouts) are additional profiles designed for fastening double-glazed windows.
Glazing beads can be manufactured with a co-extruded sealing gasket.
Connecting profiles (connectors) - profiles designed for interlocking window and balcony door frames with each other in structures consisting of two or more products. Connectors can connect frame profiles at different angles and are selected taking into account strength requirements.
Expansion profiles (extenders) - profiles designed to increase the height of the window frame profile.
Slabs are profiles designed for dividing the glazing fields of sashes.
Decorative overlays are overhead decorative profiles glued to a double-glazed window from the inside and outside and forming a false binding.
Flashings are profiles designed to drain water from the window structure.
Facing profiles - profiles for finishing window slopes (corners, platbands, trims, etc.). Cladding profiles can form various systems.
Controlled ventilation is the organization of ventilation of rooms with different air exchange rates due to the design solutions of products.
Self-ventilation is a system of limited air exchange through the channels of profile chambers or through climate valves built into window units in order to regulate the air humidity in the room and prevent condensation on the internal surfaces of the windows.
Durability is a characteristic of products that determines their ability to maintain performance qualities for a given period, confirmed by the results of laboratory tests and expressed in conventional years of operation (service life).
