Plastic entrance door blocks GOST. Technical characteristics and GOST standards for PVC doors. Packaging, transportation and storage

During construction or production, established norms and standards are always taken into account, which make it possible to create safe, durable and durable products. This also applies to PVC doors, namely their manufacture and installation. Recommendations differ depending on the type of product, but GOST contains all the necessary information taking into account the design features.

Why are GOST requirements needed?

A set of rules and regulations relating to various construction, industrial and installation work, called GOST. This list includes many points, each of which contains recommendations for making or carrying out certain actions.

GOST also contains information on the production and installation of PVC doors. The standards include safety rules, optimal parameters and manufacturing methods, recommended installation techniques and a list of standards that must be met. quality products. If the PVC doors were produced in accordance with established rules, then they are distinguished by safety, long service life, and comfortable operation. Thus, GOST requirements are mandatory to comply with, as they are aimed at creating products of the best quality.

When manufacturing and installing PVC doors, GOST requirements are taken into account

Before installing, constructing or manufacturing polyvinyl chloride structures, you should familiarize yourself with these rules. It is impossible to know the entire set of quality requirements, so it is best to study only the necessary paragraph. To do this, all sections of GOST are designated by a set of letters and numbers, and also have a designation in the form of a name.

Plastic doors: production and installation according to GOST

GOST 30970 contains the basic requirements that are taken into account when manufacturing doors made of polyvinyl chloride. This standard was approved in 2014 and includes standards for swing, sliding and other types of structures. The requirements apply to all frame-type models, but not fireproof, bulletproof and other special-purpose options.

GOST takes into account the features of all frame doors

Collection standard requirements classifies PVC doors according to five criteria:

Purpose. Plastic structures belong to group “B”, which includes all canvases that are installed inside different rooms.
Fill type. Doors can be with glass or a blank plastic insert, and there are also combined models.
Opening method. According to the design, the canvas can be hinged, sliding, single- or double-leaf, double-leaf with different floors.
Decorative finishing of profiles - color and pattern may vary.
Opening mechanism and direction. Doors can be left or right, sliding, moving in any direction.

GOST specifies all the terms that allow you to clearly define the purpose of a particular part of the PVC door system. The standards cover every major element of the product.

Requirements for door blocks

According to GOST, door systems are created from profiles made of polyvinyl chloride and supplemented with steel liners. This also applies to connections. corner type. In this case, the area of the frame and door complex should not be more than 6 m2, and the maximum allowable area of each door is 2.5 m2. If structures are manufactured whose parameters exceed these standards, then their strength characteristics must be confirmed by tests and calculations taking into account current standards.

PVC entrance doors are in great demand and are used everywhere

Basic requirements for the manufacturing process and quality of plastic door systems expressed as follows:

The maximum permissible deviations of the door block parameters are no more than +2.0 or -1.0 mm. The static load applied to the upper right angle of the folded webs of folding products is no more than 1,000 N.
The seams in the welding area must not have defects, unchecked areas or cracks. It is not allowed to change the shade of PVC at the seams.
All reinforcing elements and liners are fixed to inside frame with two self-tapping screws. The distance between the fastenings is no more than 400 mm. This figure for external systems is 300 mm.
Door panels can be filled with high-strength glass. Multilayer panels are also applicable.
The sealing gaskets must be resistant to atmospheric changes, mechanical stress and chemicals. They allow for a tight fit, which can be adjusted by adjusting the fittings.

There are a large number of requirements, taking into account which the production of high-quality plastic doors is carried out internal use. At the same time, attention is paid to the installation of systems, and the relevant rules are specified in GOST 30971–2012.

From correct installation Comfortable operation of a PVC door depends

Standard PVC installation doors was developed based on an analysis of the results of operating the blocks over many years. Therefore, the code of practice contains all the necessary information regarding this process. The main points are as follows:

materials used during installation must ensure tightness, absence of local or other freezing, resistance to operational loads, and long service life;
defective places doorways must be puttied, and all edges must have smooth edges, and if the walls have voids, they are sealed with rigid foam insulation;
materials must be environmentally friendly and safe for human health and the environment, waste disposal is carried out through industrial processing;
The constructed layers of the assembly seam are assessed visually with illumination of at least 300 lux at a distance of 40 - 60 cm.

Such installation requirements allow you to control the quality of the manipulations of masters installing plastic doors. These standards apply when installing PVC doors and windows of any design.

GOST for PVC internal doors

The standards for the installation of internal and external plastic doors are different, since each type of system must meet the conditions of use. For internal structures, requirements are imposed that ensure safety, easy operation and aesthetic appearance of PVC products. Interior systems are indicated by the symbol “B”.

PVC internal doors are subject to less stringent requirements than external ones.

GOST 30971–2012 contains the main standards relating to internal and external PVC doors. There is no separate section for each type of structure, but in the installation and manufacturing sections there are requirements for DPV such as:

door internal type may be equipped with a threshold or not, and if such an element is present, then it must have a continuous contour in the lower horizontal section, and its fixation is carried out by mechanical connection details;
assembled canvas door block equipped with a threshold, should not sag by more than 1.5 mm;
internal burglary-resistant doors must withstand static loads on the leaf area from 1300 N, applied to open the product can be more than 100 N;
reinforcing liners should not be joined or torn along the length; tile or roll or panel structures are used as panels for plastic doors;
installation is carried out only in a flat, clean opening with strong walls without chips, potholes and dust, carried out in stages in accordance with the technical map developed depending on the time of year, climatic features and necessary operations for fixing the door block;
Deviations on each side of the opening can be no more than 4 mm; checking is carried out using a hydraulic level, measuring the diagonals of the opening, as well as a laser-type plane builder.

Internal structures made of polyvinyl chloride are mounted in a previously prepared opening. The work is carried out by professional craftsmen, and acceptance takes into account quality, evenness and the absence of large gaps.

PVC external doors according to GOST

The requirements for the manufacture and installation of external doors are met as precisely as possible, because they protect the premises from dust, noise, cold, and unauthorized entry.

Input plastic doors have better heat and sound insulation than internal ones

One of the mandatory requirements that high-quality external doors must meet is a multi-point locking system. This is especially true for products characterized as burglary-resistant structures. In this case, the distance between the locks should not be more than 750 mm.

Entrance curtains are equipped with closers that ensure easy movement of the blade and allow people with disabilities to move disabilities. The threshold, which is made of aluminum with an anti-corrosion coating and equipped with drainage holes, requires special attention. This allows you to make the doors easy to use and protected from moisture.

Entrance doors can be of any color and design

The basic requirements for the manufacture and installation of external PVC systems are expressed as follows:

the recommended threshold height is 20 mm; if the parameter value is different, then this part of the structure should not become an obstacle to the movement of people;
doors installed on escape routes from the premises must open outward; they can be single- or double-leaf;
it is allowed to use burglary-resistant structures of groups A and B, for which corner reinforcement parts and a multi-bar locking system with 4th class locks are used;
External door leaves must be equipped with a system of holes for drying the gap between the panels and other parts; two holes are provided in the lower and upper profiles during manufacturing;
When installing external panels, materials that are resistant to atmospheric changes are used; the installation seam cannot cause cold penetration into the room.

External fabrics must have a particularly durable filling, as well as a high degree of thermal insulation and tightness. These properties are present due to the use quality materials for the manufacture of doors, careful installation and compliance with GOST.

GOST requirements for filling door panels

External burglar-resistant or internal plastic doors consist of profiles, fittings and have filling, presented in the form of panels. These inserts can be made of glass or plastic.

PVC doors can be of any color and equipped with glass

GOST assumes the following features of high-quality filling:

three-layer filling is represented by panels consisting of aluminum and plastic facing sheets;
single-layer filling is made in the form of foamed rigid polyvinyl chloride;
the thickness of the sheets is at least 15 mm;
installation and design of filling fixation units is carried out in such a way as to prevent the possibility of breaking the canvas from the outside;
Glass whose height is more than 1250 mm, width more than 650 mm, and thickness less than 4 mm is not used.

If the door filling meets the basic requirements of GOST, then the structure will be as reliable and durable as possible. And the quality of installation and manufacturing affects sound insulation, which is important for doors installed in private residential buildings.

GOST and marking of PVC doors

Each type of plastic door and its features are indicated by a specific marking that corresponds to GOST. For example, the symbol “A” marks the entrance external canvases, “B” - the entrance interior doors With landings, “B” - interior or simple internal systems, installed to separate rooms.

External doors made of plastic are in demand due to their high performance characteristics.

By GOST PVC doors are also marked taking into account the purpose of the product and the filling of the leaf:

DNP - external doors with PVC profile;
DPV - internal with profile;
DPM - interior doors;
the filling is designated: G - solid, O - glazed, Km - combined, D - decorative;
design: P - doors with a threshold, Bpr - without a threshold, F - with a transom, Kz - with a closed frame, Op - single-leaf systems, Dp - double-leaf, L or P - left or right, respectively, and burglary-resistant means Dv;
sliding - Rz, swing - R, folding - Sk.

The marking of the door leaves is presented in the form of a set of symbols, which includes the designation of the design type, purpose, opening option and door filling structure.

Plastic doors are varied, but their production and installation are always carried out by specialists who know all the requirements and established GOST standards. As a result of compliance with a set of rules, safe, beautiful and durable structures are obtained.

Today there is no person who has not heard of PVC doors, also called metal-plastic or simply plastic. Using them in Everyday life, how often have we wondered what it is?

Such doors are usually made from polyvinyl chloride (PVC) material reinforced inside aluminum structures. Hence the name - metal-plastic. PVC is a difficult to ignite and self-extinguishing material, resistant to atmospheric influences, as well as the destructive effects of alkalis and acids, and not subject to rapid wear. It is these characteristics that allow it to be used for the manufacture of door frames. Also, a PVC door is much cheaper and often more beautiful, as evidenced by customer reviews.

Anyone who buys a PVC door should know that the opportunity to choose a truly high-quality product is regulated by law. Involved since 2002 State standard for metal-plastic doors. It is called "Door blocks from PVC profiles"(GOST 30970–2002).

This standard describes the main types of metal-plastic doors and their technical characteristics required by production. GOST obliges manufacturers to adhere to all quality standards described in it. Therefore, when purchasing a metal-plastic door, in order not to blindly trust the seller, it is important to understand the basic concepts of GOST.

Typology of PVC doors according to GOST

In accordance with GOST 30970–2002, metal-plastic doors are divided into:

Regarding the purpose, the door can be external or internal. An internal door can be an interior door, an entrance door to an apartment or for a bathroom;
Regarding the type of filling of the door frame:

glazed PVC door, into the frame of which a double-glazed window or transparent glass of any type is inserted;
a blind door whose door leaf is opaque. It can also be: light (when the lower part of the door is not transparent, but the upper part allows light to pass through) and decorative (when the PVC door leaf is equipped with an architectural pattern);

Regarding its design metal-plastic door May be:

with one canvas (right or left) and with two canvases (the same or different widths);
with a fixed sash or one that opens;
with or without a threshold, with or without a frame box;
regarding the type of PVC profile.

Here the classification is based on the number of cameras profile system, from which the door is made. Profiles come with two, three or big amount cameras;

Regarding the profile finishing option, the PVC door can be white or another color, covered with a laminating film or with a co-extruded front covering.

Technical requirements for PVC doors according to GOST 30970–2002

The state standard quite strictly regulates the parameters that the production of plastic doors can afford - these are dimensions, filling of the canvas, permissible deviations during manufacturing. Accordingly, requirements are put forward in relation to fittings. also in this document measures for quality control of products, standards for their packaging, transportation and storage are prescribed.

Operating characteristics of a plastic door

To ensure that the door you buy satisfies your needs and maintains the necessary microclimate in the house, when choosing, you need to pay attention to its main characteristics:

Heat transfer resistance may depend on thickness insulation material, but should not go beyond 0.8-1.2 m²xC/W.
Air permeability is no more than 3.5 m³/(hm2).
Insulation from sound waves is not less than 26 dBA
The state standard also establishes that the number of years of use for a PVC profile must be at least 40, for a double-glazed window - at least 20, for a seal - at least 10. The number of openings and closings during this period can be at least 500,000 times.

Strength groups of metal-plastic doors

When purchasing, the strength group of the door is also an important indicator. There are only three of them: A, B, C. The strongest, according to this GOST classification, are the doors of group A. You can also find out about this by reading customer reviews.

What deviations can be considered a defect in the production of PVC doors?

Production in violation of the requirements of the State Standard occurs in cases where:

There is a difference in the dimensions of the finished product and the dimensions indicated in project documentation. The difference should not be more than 2 mm and less than 1 mm. The difference in diagonal length for PVC doors should not exceed 2 mm for a door leaf measuring 1.5 sq.m and 3 mm for larger doors.
On door leaf scratches, chips and other deformations are detected, as well as differences in color or gloss that are visible to the naked eye.
The door opens and closes with strain and force.
There are deviations in technical specifications from those stated in the documentation.
Deviations from GOST requirements during installation.

When purchasing a PVC door, do not forget that you have the right to demand compliance with the requirements of the State Standard from any company operating in the Russian Federation.

Often when studying quality characteristics, features and parameters of doors, you may encounter incomprehensible abbreviations and abbreviations that make it difficult to understand the material presented by the manufacturer. To understand the essence of what is written, it is not necessary to become an expert in the field of the door industry or try to take the place of the manufacturer. This article will help you figure it all out.

Many standard meanings are used to shorten long words. For example, in documents on certification, standardization, as well as in the catalogs of many manufacturers, you can find the following abbreviations:

DG– the door is solid;

DHF- solid paneled door;

BEFORE- glazed door;

DLO\DOL- glazed laminated door;

DFO\DFO- paneled glazed door;

DN– external door;

DU– reinforced or insulated door;

DSH– panel door (with prefix U – reinforced);

DS– service door;

DK- a door on which the canvas swings.

Many words are not clear in their meaning, as they have foreign origin or unclear definitions. Let's look at some of them using an example:

Mold– if the doors are paneled or glazed, these elements are enclosed in a profile with an edge shape.

Knobset– handle-knob.

Layouts– profile slats that hold the glass in the door.

Block- a structure that already consists of interconnected door frame (door jamb) and door leaf with fittings.

Doviator– a mechanism for locking doors on all sides.

Dormas, backset– the distance from the front of the lock to the keyhole.

Fusing– stained glass decorative element decorating the door instead of glass.

Panel– thin frames in the door leaf stand out as a decorative element.

In the descriptions of doors from the DoorExpo company and other manufacturers, there is often an indication of the materials that are used for their production. The most common for doors and door fittings are:

Antipyrine– impregnation, which increases the fire-resistant properties of the door leaf.

MDF– wood-fiber board, which is used for cladding or making elements of interior doors.

Powder paint- is polymer material, providing protection metal elements or the entire steel door.

Silumin– silicon-aluminum alloy, from which fasteners, handles, and locks are made.

Veneer– cut, felling of natural wood.

TsAM– an alloy of 3 steels: zinc, aluminum, copper.

The next time you see these words and abbreviations, you will be able to understand what characteristics the manufacturer has endowed with its doors.

Why are GOST requirements needed?

The set of rules and regulations relating to various construction, production and installation works is called GOST. This list includes many points, each of which contains recommendations for making or carrying out certain actions.

GOST also contains information on the production and installation of PVC doors. The standards include safety rules, optimal parameters and manufacturing methods, recommended installation techniques and a list of standards that quality products must meet. If PVC doors were produced in accordance with established rules, then they are distinguished by safety, long service life, and comfortable operation. Thus, GOST requirements are mandatory to comply with, as they are aimed at creating products of the best quality.

The marking of the door leaves is presented in the form of a set of symbols, which includes the designation of the design type, purpose, opening option and door filling structure.

GOST 30970 -2002: plastic entrance doors

Doors made of plastic, although relatively recently, have become quite firmly established in our everyday life. If at first they were the prerogative only for office and public buildings, then today plastic, as they say, “steps on the heels” of wooden carpentry. Here, as they say, there are three pleasures in one bottle: durability, affordable price and design, which is sometimes not inferior to wood products.

The instructions proposed in this article will tell you what requirements plastic doors GOST 30970 must meet, how they are classified, how they are marked and installed - in general, about everything that may interest our readers.

According to GOST 30970-2002, plastic door products classified according to five criteria. The first is, of course, the purpose.

There are three groups here:

"A"— entrance to the building;
"B"— entrance to the apartment or hall from the staircase;
"IN"- interior doors.

Note! Group “B” includes not only products with a rebate, which were the only design option indicated in GOST for plastic doors from 2002. The standard, updated in 2014, now applies to all kinds of folding and sliding structures installed in partitions, exits to the terrace, and other architectural and design solutions, one of which is shown in the photo below.

GOST 30970 2014 - exit to the terrace

Filling canvases

The second feature by which GOST classifies plastic doors is the filling option for the panels. Everyone knows that they can be glazed, solid throughout the entire height, or combined, with solid filling in the lower part.

Blind doors are most often installed at entrances, while combined doors are installed in institutions and residential buildings. In apartments this is most often an exit to a balcony or loggia (see).

Full glazed interior design

But still, when it comes to doors inside residential premises, fully glazed panels occupy a leading position. The reason is simple: such a door will fit into any interior without any problems and, in addition, will improve its natural lighting daytime. Therefore, I would like to say something about glazing separately.

Double-glazed windows

For glazing plastic doors, non-single sheet glass is used. Double-glazed windows that are a glued volumetric structure are more suitable. This is done both to preserve heat and to enhance the strength of the door glazing.

Double-glazed windows consist of a spacer frame, a desiccant and two types of sealant, and are manufactured in accordance with GOST 54175*2010.

There are two design options for double-glazed windows: single-chamber, marked with the abbreviation SPO, and two-chamber - SPD. We think everyone understands that the two-chamber version consists of three glasses, between which two isolated cavities are formed. By agreement with the customer, the manufacturer can make a structure of 4 or more sheets, and even install a decorative frame between the chambers.

Double-glazed window designs

The chamber space is filled with some inert gas or simply dried air. The main thing is that the properties of the gas cannot deviate the characteristics of double-glazed windows from the requirements of the standard. Many types of base material can be used to make double-glazed windows.
In addition to colorless sheet glass, polished and unpolished reinforced glass, pigmented glass, hardened glass, multilayer glass and sun-protective glass are used. Glazing can also be patterned or decorative (see), with a soft or hard coating.

With patterned glass

In the production of double-glazed windows, it is allowed to use any type of glass, as long as the final product meets the requirements of GOST. Their thickness can vary between 14 mm and 60 mm, but deviations from the nominal value should not exceed 1 mm for one camera. The inside of the glass must be clean, without traces of dust, sealant, markings, fabric lint or fingerprints.

The sealant layer around the perimeter must be complete and have no breaks. Tightness, as well as the absence of any optical effects when it comes to transparent glass, are the main requirements of the standard for these products. The service life of a properly manufactured double-glazed window is at least twenty years.

Designs of entrance products made of plastic

Regarding the designs and sizes of double-glazed windows, the manufacturer makes decisions in accordance with the purpose and operating conditions of the doors, as well as according to the wishes of the customer. The state standard only outlines the boundaries of what is permitted for the manufacturer.

So, we come to the third criterion by which products are classified - this Constructive decisions blocks. In addition to those opening to the left or right, this includes products with two blades, symmetrical in width or unequal in width.

Frame design

Double-floored products differ in the design of the narthex: the canvases can be separated by a vertical impost or not have such a feature. Impostless doors are closed using a frame - a special profile installed on the sash. There are also burglar-resistant doors, as well as options with a transom, which can be either opening or solid.
Also, the design differences between plastic doors concern the threshold. If there is one, then the standard requires that it be continuous along the entire contour. If the structure does not have a threshold, then the frame of the box should be closed, and the profile in its lower horizontal part should not differ from the vertical element in cross-sectional size. Door opening mechanisms also divide them into groups. There are three of them: hinged, folding and sliding (see).

Metal-plastic structures for a loggia with a blind transom

It only remains to mention that thanks to the use of profile doors with different front trim, the products have completely different appearance. This is not only the familiar white plastic, but also a mass-painted profile.

It can also be finished surface by painting, laminating or having a co-extruded sprayed face.

Marking

To make it clear how doors are marked, here is a list symbols in table form:

Symbol	Decoding
DPM	The first two letters in this abbreviation stand for the phrase PVC door. The last letter determines its purpose. M – interior, group “B”.
DPV	Internal door of group "B".
DPN	External - group “A”.
G	Blind canvas
ABOUT	Full height glazing
Km	Combined filling
D	Decorative insert
P	With a threshold
Bpr	No threshold
Kz	Closed box
F	With transom
Op	Door with one leaf
Dp	With two canvases
L	Opens to the left
P	Opens to the right
Vz	Tamper-resistant
R	Swing mechanism
Rz	Sliding mechanism
Sk	Folding

These are the basic designations. Many manufacturers additionally introduce qualifying letters, for example: “T” - tambour, or “C” - products for the bathroom. TO letter designations They also add digital ones that determine the size of the opening.

Requirements

Of course, no one installs plastic doors with their own hands. This is done by the installation team of the company that accepted the order and manufactured the product. Anyone interested in the process can watch the video in this article, and we will tell you what installation requirements GOST imposes.

So:

First of all, they relate to the assembly of canvases and boxes from PVC profiles, which must be reinforced with steel liners and corners. In doors with impost narthex vertical elements must be fixed not only by welding, but also with the help of mechanical fastenings, for which the standard provides diagrams of the main components and connections.
