• aspect ratio of the interior door;
• the presence of error-free connections of the necessary parts of the product;
• required level of rib stiffness.

For manufacturers interior doors before the start of mass production, an examination identifying the above factors is a necessary condition. During such a study, design flaws may be identified, which in turn contribute to the removal of this product from production.

This examination is beneficial and useful also for potential buyers. First of all, it can guarantee the purchase of a quality product.

Independent examination is a study of an object conducted by a qualified expert in order to establish significant parameters and properties of this object. When conducting an examination, the specialist is guided by knowledge in the field of science and technology, competencies in the field of art and craft. Conducting both independent and forensic examinations assumes the absence of influence of third parties on the results obtained.

Forensic examination is characterized by a special procedural status and is carried out in connection with the consideration of criminal, civil, administrative and arbitration cases. Forensic examination is regulated by the provisions of procedural codes and laws.

In our opinion, it is not correct to draw a rigid line between the concepts of judicial and independent examination, since the legal status of examination does not entail a change in the applied methods and quality requirements.

Examination of counterfeit products

This type of examination is aimed at establishing signs of the use of someone else’s trademark in the manufacture of products. Most often, unscrupulous entrepreneurs use someone else’s brand not for new (unique) products, but copy existing products as accurately as possible.

Research is carried out by a group of effective specialists, which includes experts, patent attorneys, marketers, and sociologists. We use our own collections of legitimate product samples and continually build our knowledge of specific products by direct dialogue with copyright holders and certification. Today our company is known to many business representatives as a professional in its field. They trust us and we improve.

Who needs expertise?

Brand owners. For them, this is a way to prove the facts of illegal attacks on intellectual property and bring the perpetrators to responsibility established by law. This type of work leads to a reduction financial losses, and increasing the degree of trust in the brand and product quality;

Law enforcement agencies. The forensic units of the Ministry of Internal Affairs practically do not engage in such research. Contacting us executive makes a decision to order an examination, and we acquire procedural status;

Consumers ( individuals). Most often, the service is needed by those who have already purchased some product and after some time doubted its quality. However, often the consumer voluntarily and consciously chooses a “branded” counterfeit. He does not need to understand the signs of difference, since its cost in relation to the original is 100-350% lower, which speaks for itself.

The fight against counterfeit products has become a global trend and in this sense, we sincerely believe that each of us should be very careful about the choice of products purchased. Are you sure that the ones you are using Construction Materials or are the spare parts for your car original? We do not, especially when in our Conclusion we conclude that there are signs of counterfeit brake pads...

Professional examination of doors, their elements and/or correct installation of the structure must be carried out by certified specialists who have the appropriate permits.

Results of expert checks

After the examination of the installation of the door or the product itself comes to an end, the client is given a written expert report. In the conclusion, all identified defects are described in detail (photo materials are attached), objective reasons occurrence of malfunctions and, if necessary, an estimate for troubleshooting. The report also contains references to the requirements and regulated standards of TU, ​​SNiPs, GOSTs and other regulatory documents.

The expert report shows the actual condition of purchased but not yet installed or already installed door structures. The document has official force and can be used to resolve conflicts in court or pre-trial procedure(between installers and service customers, developers and residents, manufacturers and buyers).

The important point is that, based on the opinion of an independent expert, the injured party can count not only on a partial/full refund of the money paid for the purchase and/or installation of the door. But also compensation for the expert’s work in full.

What can you check?

During the research, experts analyze the verticality of the installation door frame and its condition, study the geometry of the dimensions of the structure. They evaluate the compliance of the product characteristics with GOSTs and technical specifications, check its mechanisms, structural elements and accessories, make sure of sufficient or insufficient reliability and performance.

Exact types and volumes necessary work largely depend on what kind of door we are talking about. Thus, the examination of a metal door installed on staircase, will be carried out according to one scheme, and the study of its interior wooden analogue will be carried out according to another.

Requirements for the quality of external street, entrance and interior doors

The most stringent requirements are placed on door structures that “look” onto the street. Since their tasks are the most numerous: thermal protection of premises from negative climatic factors, fencing from uninvited guests, decorating the exterior of the building.

If the client needs an examination of the front door installed at the entrance to the home, the requirements for the quality of the product and its installation will be slightly less numerous and strict. After all, the structure is not exposed to precipitation and is operated at a comfortable temperature.

In case of any entrance doors, wherever they are directed - in the corridor or on the street, the research will be carried out:

• Organoleptic method. The expert will examine the working mechanisms, scratches and chips. By analyzing the damage and establishing their nature, he will understand whether they arose due to improper use of the door or due to a manufacturing defect.
• Documentary method. Specialist determine design features, which could be the root cause of the malfunction. He will work carefully working documentation on the door, including technical papers. Ultimately, it will answer the question of who is to blame for the problem: the buyer, the installers or the manufacturer.

Minimum requirements for interior doors: aesthetics and appearance. By the way, precisely in the case of interior products most often you can detect a manufacturing defect, hidden or obvious.

However, examination of interior doors is often carried out with the aim of proving incorrect installation. It also happens that instead of a laminated structure, the buyer receives a product with a laminated coating.

Cost of services

The exact cost of an expert’s work depends on many conditions. For example, do you need an examination of the door frame or the entire door. Average research fees interior designs are 5-7 thousand rubles, for the study of input products they are slightly higher - 8-10 thousand rubles.

If you require an expert to speak in court, you will have to pay for this service separately.

1.1. To conduct an independent examination, you can contact any expert organization and receive an expert opinion. Good luck.

2. During manufacturing and installation, violations were committed that do not comply with GOST 31173-2003;

3. Manufacturing defects and violations technical specifications on the installation of the door block became the main cause of defects during the work.
