Test Methods

7.1. Profiles after manufacturing and before carrying out acceptance tests must be kept at a temperature of (21 +/- 3) ° C for at least 1 hour (marking and the presence of a protective film can be controlled during production).

When conducting periodic tests, as well as if the profiles were stored (transported) at a temperature different from the specified one, they are conditioned at a temperature of (21 +/- 3) ° C for a day before testing.

Tests, unless otherwise specified, are carried out at (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 the established requirements for permissible deviations by no more than 50%.

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

7.6. Profile shape deviations are determined according to Figure 2 on three meter segments (samples).

For the measurement result of each parameter, the arithmetic mean of the measurement results of three samples is taken. In this case, the value of each result must be within the tolerances specified in 5.2.5.

7.6.1. Deviations from the straightness of the front walls of the profile along the cross section and from the perpendicularity of the outer walls of the profiles of the boxes are measured with a probe, determining the largest gap between the profile surface and the side of the square according to GOST 3749 (Figures 2, a; 2, b).
To determine the deviations from the parallelism of the front walls of the profile along the cross section, two metal rulers are used according to GOST 427, which are pressed with ribs one above the other perpendicular to the longitudinal axis of the sample (Figure 2, c).
Measure the distance between the edges of the rulers with a caliper per 100 mm length. The amount of deviation from parallelism of the front walls is determined as the difference between the largest and smallest dimensions.
Measurements are carried out at three points along the length of the sample. The value of the largest deviation is taken as the measurement result for each sample.
7.6.2. To determine the deviations from the straightness of the sides of the profile along the length, the sample is applied alternately by all external surfaces to the calibration plate and, using a probe, measure the distance between the profile and the surface of the calibration plate. The maximum value of this distance is taken as the deviation from straightness (Figure 2, d).
Note. For testing, it is allowed to use the surface of any measuring instrument (for example, a building level in accordance with GOST 9416) with a flatness tolerance of at least the ninth degree of accuracy in accordance with GOST 24643.

7.7. The deviation of the nominal dimensions of the cross section is determined on five segments of the profile with a length of 50 - 100 mm.
Dimensions are measured at each end of the segment with a caliper according to GOST 166.
It is allowed to control the deviations of the nominal dimensions of the cross sections of the profiles using optical and other instruments that provide a measurement accuracy of 0.1 mm. In this case, the length of the segments is set in accordance with the technical characteristics of the test equipment.

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;

Frost-resistant design (M) - for areas with an average monthly air temperature in January below minus 20 ° C (control load during testing - minus 55 ° 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.

4.7 The designation of the profiles should include the designation of the product material, the name of the manufacturer (or its trademark) or the name of the profile system according to the technical documentation, the profile article according to the technical documentation, the designation of this standard.

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).
