Note - Shtulp profile (shtulp) - an overlaid profile, rigidly fixed to the sash and providing a non-multiple porch.

Additional profile - a profile that does not perform a strength function as an integral part of window, balcony and door structures (connecting, expanding and shtulpovye profiles, glazing beads, ebbs, trim, decorative overlays, details of decorative bindings, etc.).

External front wall of the profile - the wall of the profile, which is visible in the assembled and closed window or door unit.

External non-front wall of the profile - the outer wall of the profile, which is not visible in the mounted and closed window or door block.

Inner profile wall - a profile wall (partition) located inside the space bounded by the outer walls of the profile.

Deviation from straightness - deviation of the longitudinal axis or any edge of the profile from a straight line.

The batch is considered the number of profiles of the same article, manufactured on the same production line in the volume of shift production. It is allowed to take a smaller number of profiles for a batch, while the batch size is set in the technological documentation.

Confirmation of acceptance of a batch of products by the technical control of the manufacturer is the execution of documents on acceptance and quality.

6.2 When products are accepted by the consumer, the number of profiles of the same brand delivered by one vehicle and drawn up by one quality document is taken as a batch of products (unless other conditions are specified in the supply contract).

6.3 The quality of the profiles is controlled by conducting acceptance and periodic testing in accordance with the requirements of table 4.

6.4 Acceptance tests are carried out for each batch of profiles. Acceptance tests within one shift production of profiles are repeated if new batches of at least one constituent component are introduced into the composition for extrusion.

6.5 Acceptance tests are carried out by the quality service (laboratory) of the profile manufacturer.

To check the compliance of the profiles with the requirements of this standard, at least 5 pieces are selected from each batch by random selection. profiles on which the marking, length, quality of the cut of the ends are checked.

It is allowed to select measured sections of the profile directly from the production line.

Segments (samples) with a length of (1000 ± 5) mm are cut out of the measured profiles to check the maximum deviations from the shape, mass and appearance indicators.

The number of samples for all types of tests is determined in accordance with the requirements of clause 7.

After checking the indicated indicators, samples are cut out from meter lengths of the main profile to determine the physical and mechanical parameters and check the maximum deviations of the geometric dimensions of the section, and tests are carried out according to table 4.

Upon receipt of unsatisfactory test results for at least one of the tested indicators, repeated tests are carried out on a double number of samples taken from other dimensional profiles of the same batch.

Upon receipt of unsatisfactory results of repeated tests, a batch of profiles is not subject to acceptance.

6.6 Periodic tests according to the indicators indicated in Table 4 are carried out when the technology (recipe) is changed, but at least once every three years.

The reduced heat transfer resistance of the combination of profiles is determined when making changes to the design of the profiles.

Durability and resistance to chemical attack is determined by changing the technology (recipe).

When setting profiles for production, they are carried out qualification tests to comply with all requirements of this standard. In justified cases, it is allowed to combine qualification and certification tests.

Tests are carried out in independent testing centers accredited for the right to conduct them.

6.7 The consumer has the right to conduct a quality control check of the profiles, while observing the established sampling procedure and test methods specified in this standard.

6.8 By agreement of the parties, acceptance of products by the consumer can be carried out at the manufacturer's warehouse, at the consumer's warehouse or in another place specified in the supply contract.

6.9 Acceptance of products by the consumer does not relieve the manufacturer from liability in case of detection hidden defects leading to violation performance characteristics products during the warranty period.

Tests, unless otherwise specified, are carried out at a temperature of (21 ± 3) °C.

7.2 The marking and the presence of a protective film are checked visually.

7.3 When measuring linear dimensions, as well as deviations from the shape of products, they are guided by the requirements of GOST 26433.0, GOST 26433.1.

7.4 The length of the profiles is measured on five measured segments with a metal tape measure of the 2nd accuracy class according to GOST 7502.

The test result is considered satisfactory if four out of five (when retesting nine out of ten) measurements meet the established requirements, and the result of the fifth (tenth) measurement differs from established requirements to allowable deviations of no more than 50%.

7.5 The procedure for determining the quality of cut profiles along the length is established in the technological regulations.

External non-front wall of the profile - the outer wall of the profile, which is not visible in the mounted and closed window or door block.

Inner profile wall - a profile wall (partition) located inside the space bounded by the outer walls of the profile.

Deviation from straightness - deviation of the longitudinal axis or any edge of the profile from a straight line.

Profile width - the largest size of the cross section of the profile between the front surfaces (outer surfaces of the outer front walls).

Profile height - the largest cross-sectional dimension of the profile in the direction perpendicular to the profile width.

Profile combination - connection nodes of mating profiles (for example, a frame profile - a sash profile with a glazing bead), which determine the main technical parameters of the profile system.

Profile article - alphanumeric designation of a specific profile design included in the profile system, set in the technical documentation.

Definitions of structural elements of profiles are given in GOST 30674 and in Figure 1.

4 Classification and conventions

4.2 According to the design, depending on the number of rows of internal chambers along the width of the section, affecting the thermal characteristics, the main profiles are divided into: one-, two-, three-, four-chamber and more.

4.3 Depending on the resistance to climatic influences, the products are divided into types of execution:

Normal execution - for areas with an average monthly air temperature in January of minus 20 ° C and above (control load during tests - minus 45 ° C) in accordance with current building codes;

4.4 Depending on the thickness of the front and non-front outer walls, the main profiles are divided into three classes indicated in table 1.

Table 1

The thickness of the inner walls of the profiles is not standardized.

Note - The classification of profiles by wall thickness does not make a difference in the quality requirements of profiles or window structures from them. The wall thickness is an indirect characteristic of the dimensional stability and strength of the profiles.

4.5 According to the type of finishing of the front surfaces, the profiles are divided into:

White, mass dyed;

Finished with a decorative film (laminated);

With co-extruded face.

4.6 According to the reduced resistance to heat transfer, profiles (combinations of profiles) are divided into classes:

class 1 - reduced resistance to heat transfer St. 0.80 m 2 - 0 C / W;

Symbol example:

PVC profile "Plast" 3067 GOST 30673-99.

Polyvinyl chloride profile manufactured by Plast, article according to technical documentation - number 3067.

When designating a frost-resistant version of profiles, the letter “M” is added to the article, for example:

PVC profile "Plast" 3067 M GOST 30673-99.

In the case of the manufacture of profiles finished with a decorative film or with a co-extruded coating, the words “decor” or “co-extruded” are added to the designation of the profiles in the accompanying documentation and the passport for the products, respectively, along with the reference sample number. When applying a film or coating on one side, add the word "one-sided".

It is allowed to enter additional information into the designation of profiles, which is set in the technical documentation for profile systems.

In the case of export-import operations, the designation of profiles may be specified in the contract for the supply of products (including entering alphanumeric or other information).
