GOST requirements and markings for metal doors. We study GOST requirements for metal doors GOST external steel doors

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.

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.

If you pay attention to the requirements that apply to counterfeit fire safety, and, as a consequence, to fire doors at 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 outside temperature and will not cause burns upon contact with 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 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.

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
Absence through holes and crevices	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 operate as smoothly as possible and not require much 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.

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 inspection and acceptance testing
7.2.1 The geometric dimensions of products, as well as the straightness of the edges, are determined using the methods established in GOST 26433.0 and GOST 26433.1.
Maximum deviations from the nominal dimensions of product elements, the difference in diagonal lengths and other dimensions are determined using a metal measuring tape in accordance with GOST 7502, calipers in accordance with GOST 166, probes in accordance with ND.
Maximum deviations from the straightness of the edges are determined by applying a straight edge in accordance with GOST 8026 or a building level with a flatness tolerance of at least the 9th degree of accuracy in accordance with GOST 9416 to the tested part and 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 in accordance with 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 in accordance with 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.

7.3.2 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.

Note - Upon completion of the tests, the door units must remain operational, while the lock bolt and latch must freely enter their mating parts.

Before and after testing the door blocks for failure-free operation, it is recommended to check the tightness of the sealing gaskets in accordance with 7.2.6.
When testing door blocks for resistance to a static load acting perpendicular to the plane of the leaf in the free corner zone, to determine the strength class, it is recommended to use the graph of the dependence of the deflection of the free corner of the leaf on the applied load, given in Appendix D.
7.3.5 Methods for quality control of welded joints (5.3.10) are established in the manufacturer’s technical documentation in accordance with GOST 5264.

With all the variety of products offered on the modern construction market, there are products that comply with State Standards. For example, metal doors. Manufacturers that respect themselves and the consumer produce products that meet the requirements of established state standards.

What does GOST 31173-2003 say?

The provisions described by GOST 31173-2003 apply to the designs of steel door blocks with locks. The products described by the standard are intended for installation in buildings for various purposes. This regulatory document does not include the design of special-purpose door blocks that meet increased demands for explosion resistance, resistance to bullets, resistance to aggressive environments, as well as fire safety.

This document describes the types of door blocks, classification, and markings. Recommends steel grade and external and internal organization boxes and sashes. GOST 31173-2003 mentions options for possible finishing on the inside and outside of the sashes. The standard also indicates possible types heat insulator and methods of installing locks.

Let's be clear

There is no separate State Standard (GOST) for fire doors. The existing GOST 31173-2003 regulates only the design of metal door blocks. Those products that are called “fire doors GOST 31173-2003” are usually manufactured according to TU - Technical Conditions, compiled by the manufacturer taking into account the recommendations described in GOST 31173-2003.

The manufacturer then receives a fire safety certificate for their product. This document is valid for three years. After the certificate expires, the manufacturer must go through the procedure for obtaining a fire safety document again.

This certificate is issued after passing a product sample made in accordance with TU or GOST 31173-2003. The combustibility tests of door structures are carried out according to the rules described in the State Standard “Test methods for fire resistance of doors and gates” numbered 53307-2009. Based on the test results, the product is assigned one or another class of fire resistance and a fire certificate is issued.

The essence of the test method is to expose the test product on one side to the temperature created by a special oven. The temperature of exposure to the tested product is regulated by GOST 30247.0-94. During testing, the time to the limiting state of the structure, determined by GOST 53307-2009, is determined in minutes.

The fire resistance class assigned to a product affects its scope of application and cost.

What determines temperature resistance?

The resistance of metal doors to temperature does not depend on the thickness of the metal used in manufacturing. Fire safety is affected by:

1. Thermal insulator used. In GOST 31173-2003, in the section devoted to the design of metal doors, the following is proposed for use as a filler for cavities between the inner and outer shell: polystyrene foam, mineral wool, wood or wood chip fillers. Naturally, thermal insulation made of polystyrene foam or wood is not suitable for the manufacture of fire doors. And the density and thickness of the mineral filler also affects the time that a metal door will resist the effects of fire.
2. The size of the gap between the door leaf and the frame. The smaller this distance, the greater the door’s resistance to temperature. The standard for the manufacture of metal door blocks allows maximum deviations of no more than 3 mm.
3. Availability and quality of self-foaming sealant. Fire self-foaming tape is installed around the perimeter of the door leaf. As the temperature rises, the seal foams and hermetically closes the gap between the frame and the sash, preventing combustion gases from entering the room.
4. GOST 31173-2003 establishes that the used sealing gaskets must comply with sanitary norms and other technical regulations and standards adopted in the prescribed manner. Seals must be present around the entire perimeter of the sash and the fit of the sash must be tight.

How to choose a fire door

A fire door is a structure designed to protect against the spread of fire during a fire. A fire door must retain its protective properties for some time - until firefighters arrive and people are evacuated. As can be seen from the above, GOST 31173-2003 does not apply to metal fire doors.

The general provisions of fire safety are described by Federal Law No. 123-FZ, adopted on July 22, 2008. “Technical regulations for fire safety requirements.” To choose a metal fire door, you need to pay attention to the availability of a fire compliance certificate for the selected product and fire resistance class.

Fire resistance class - what is it?

The fire resistance class is assigned to a product as a result of fire resistance tests. Depending on the number of minutes that a particular door resisted the effects of temperature as a result of testing, a fire resistance class is assigned:

1. Ei 30. Class Ei 30 has doors that are resistant to fire for half an hour. Recommended for installation in public buildings and industrial facilities.
2. Ei 60. Such doors can withstand fire for an hour. Installation of doors of class Ei 60 allows for the safest evacuation of people.
3. Ei 90. Doors with fire resistance class Ei 90 are intended for installation in buildings with an increased fire hazard: gas stations, special production facilities, warehouses for fuels and lubricants, etc.

Such fire doors can prevent the spread of fire for one and a half hours.

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.

Note - Upon completion of the tests, the door units must remain operational, while the lock bolt and latch must freely enter their mating parts.

Before and after testing the door blocks for failure-free operation, it is recommended to check the tightness of the sealing gaskets in accordance with 7.2.6.

When testing door blocks for resistance to a static load acting perpendicular to the plane of the leaf in the free corner zone, to determine the strength class, it is recommended to use the graph of the dependence of the deflection of the free corner of the leaf on the applied load, given in Appendix D.

7.3.5 Methods for quality control of welded joints (5.3.10) are established in the manufacturer’s technical documentation in accordance with GOST 5264.

8 Packaging, transportation and storage

Let's say it straight away: there is no GOST for fireproof metal doors! There is a common GOST 31173-2003“The door blocks are steel. Technical specifications", which describes General requirements for the production of metal doors. For example, one of the requirements: metal thickness door frame must be at least 1.5 mm. Each door manufacturer writes specifications (our technical conditions) according to which he will produce fire doors; naturally, it must be combined with GOST 31173-2003. The technical specifications describe the production process and materials used in detail. And only when the specifications are ready, you can apply for a fire safety certificate. To do this, the provided door sample will undergo test burning, which is carried out in accordance with GOST 53307-2009, it is called: “Test methods for fire resistance of doors and gates.” In the end, it is important whether it can withstand the necessary tests and receive a certificate, or whether it will remain just a metal door.

The fire resistance of a door will be based on the following characteristics:

1. Density and thickness of basalt wool. The greater the density and thickness, the higher the fire resistance characteristics in minutes.

2. The size of the gaps between the box and the canvas. The smaller the gaps, the higher the fire resistance rating in minutes.

3. Quality fire self-foaming tape.

The thickness of the metal, as many people mistakenly believe, has no effect when testing for fire resistance.

Once a fire door passes the burn test, it will (or will not) receive a fire resistance certificate, and according to how long it can resist fire: 30, 60 or 90 minutes, it will be assigned an Ei 30 rating accordingly. , Ei 60 or Ei 90, where “E” means loss of door integrity, and “I” means loss of thermal insulation ability (increase in unheated surface temperature by an average of more than 140 degrees Celsius). If a fire door is not only fire-resistant, but also smoke-gas-tight, it can receive a class Eis 30, Eis 60 or Eis 90, respectively.

Thus, after passing tests in accordance with GOST 53307-2009, the door receives a fire safety certificate, which is issued for a period of 3 years. After 3 years, you will have to re-test and obtain a new certificate.

In conclusion, it is worth noting that the new GOST 53307-2009 no longer includes tests:

- doors, gates and hatches for smoke and gas permeability.

Now tests for smoke and gas permeability of doors are carried out in accordance with GOST 53303-2009. As a result, you can obtain an EIS class certificate, where S means the loss of smoke and gas tightness in minutes.

- doors with a translucent filling area of ​​25% or more of the clear area of ​​the doorway.

In May 2009, Federal Law No. 123-FZ “Technical Regulations on Fire Safety Requirements” was adopted, which defined a unified base of requirements for fire-resistant structures, which states that the requirements for translucent structures do not differ from the requirements for “solid” structures ( in this context to blind doors). Now the overall thermal insulation capacity of the structure is assessed, whether it is with glass more than 25% of the total area or without glass at all.

Now manufacturers can safely produce fire doors with glazing of more than 25%, but at the same time rely on GOST for the use of fire-resistant glass GOST R 51136-2008 “Multilayer protective glass. General technical conditions".

Designation of fire doors according to GOST.

The designation of fire doors is necessary so that, by a short name, it is possible to determine the main characteristics of the door without using a verbal description. Each manufacturer of metal doors has the right to use its own designation, as this is specified in its technical specifications.

However, to designate fireproof or simply steel doors, GOST 31173-2003 “Steel door blocks. Specifications" recommends using general rules designations of metal doors for manufacturers.

This is primarily convenient for reading construction documentation, since designers adhere to the use of GOST standards in the designation.

Let's look at some popular labeling options:

1. The very first letters indicate the purpose of the product:

DSV - internal steel door block

DSN - external steel door block

DPM - fireproof metal door

D - double-field

K - with closed box

P - with threshold

L - single-field left opening

P - single-field right opening

Indoor - opening inside the room

N - opening outwards

3. Then classes according to performance indicators:

mechanical characteristics (M1, M2, M3) and

design options according to security properties (U, Z)

4. And overall dimensions in width and height

Example of designation: DSV DKN 2090-1310 M2 - internal steel door block, double-leaf, with a closed frame and opening outward with dimensions of 2090 mm. by 1310 mm. , strength class M2.

In practice, the design documentation states it more simply: CSA EI 60 2.1*1.3, but the specifications describe it in detail.
