6.1.1 Profiles after manufacture and before acceptance testing must be kept at a temperature of (21 ± 4) ℃ for at least 2 hours. Before periodic testing, and also if the profiles were stored (transported) at a temperature different from the temperature tests, before testing they are kept at a temperature of (21 ± 4) ℃ for a day.

6.1.2 Testing (preparation for testing) of profiles, unless otherwise indicated, is carried out at a temperature of (21 ± 4) ℃.

6.1.3 Sampling for testing is carried out in accordance with 5.4.2–5.4.4. Sampling for periodic testing is carried out from a batch of profiles that have passed acceptance tests.

6.1.4 When testing, it is allowed to use test equipment and measuring instruments that are not specified in this section, if their use meets the established requirements for measurement error and test conditions.

6.1.5 During acceptance tests, the results of the control are recorded in a log, in which the symbol of the profile is indicated; type, mode and test result; batch number (date) of manufacture and testing of samples; the signature and surname of the examiner. Storage of test results in electronic form is allowed.

Marking definition

The marking and the presence of the protective film are checked visually, and the conditions for removing the film are checked manually. The control of marking and the presence of a protective film is allowed to be carried out on the production line.

Sizing and Shape Determination

6.3.1 Measuring instruments:

ruler according to GOST 427;
tape measure according to GOST 7502, class 3;
metal probes 0.1–1.0 mm thick;
caliper according to GOST 166;
building level with a length of at least 1000 mm in accordance with GOST 9416;
calibration ruler with a length of at least 1000 mm in accordance with GOST 8026;
calibration square 90° according to GOST 3749;
calibration plate according to GOST 10905.

When controlling the dimensions and shape of profiles, they are guided by the requirements of GOST 26433.0 and GOST 26433.1.

6.3.2 The length of the profiles is measured on five measured segments with a tape measure. The test result is considered positive if each measurement result meets the requirements of 4.2.1.

6.3.3 Deviations from the shape of the profile are determined on three meter 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 should be within the tolerances specified in 4.15.

6.3.3.1 Deviations from the straightness and perpendicularity of the profile walls along the cross section of the boxes are measured with a probe, determining the largest gap between the profile surface and the side of the square (see Figures 1 a, 1 b).

To determine deviations from parallelism of the front walls of the profile along the cross section, two metal rulers are used, which are pressed with ribs one above the other perpendicular to the longitudinal axis of the sample (see Figure 1c). Measure the distance between the edges of the rulers with a caliper for 100 mm length. The deviation from parallelism of the front walls is defined 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.

Two 90° test squares may be used instead of metal rulers.

6.3.3.2 To determine the deviations from the straightness of the profile sides along the length, the sample is applied alternately by all external surfaces to the calibration plate, and using a feeler gauge, measure the distance between the profile and the surface of the calibration plate. The maximum value of this distance is taken as a deviation from straightness (Figure 1 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.

6.3.4 The deviation of the cross-sectional dimensions is determined on five sections of the profile 50–100 mm long. Dimensions are measured at each end of the segment with a caliper.

It is recommended 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 at least 0.1 mm. In this case, the length of the segments is set in accordance with the technical characteristics of the test equipment.

For the test result for each measurement parameter, the arithmetic mean of the measurement results is taken, and each result should not exceed the permissible maximum deviations.

6.3.5 The procedure for determining the quality of cut profiles along the length is established in the manufacturer's technical documentation.

Where m- mass of the sample, g;

L- sample length equal to 1 m;

L1- the actual length of the sample, m.

Results are rounded to the nearest 1 year.

The test result is taken as the arithmetic mean of the test results of three samples, and the value of each result must comply with the requirements of 4.2.2.

Determining Appearance Metrics

The appearance of the profiles (color, gloss, surface quality according to 4.2.8) is determined visually by comparison with standard samples.

Tests are carried out on three samples with a length of at least 250 mm with uniform illumination of at least 300 lux, directed at an angle of 45 ° to the surface of parallel samples.

Samples are examined with the naked eye from a distance of 0.5–0.8 m, the direction of the line of sight should be perpendicular to the surface and axis of the sample.

The test result is considered satisfactory if each sample meets the established requirements.

Determining the change in linear dimensions after thermal exposure

The striker must be fixed during the rebound (repeated strike is not allowed), then the striker is raised, and the sample is removed and inspected.

The sample is considered to have passed the test if, during inspection, no cracks, damage, or delamination are found on its surface.

B.2 The composition of the documentation given in B.1 includes the minimum amount of technical information that can be expanded by the manufacturer.

Annex B (recommended). Strength Calculation of Welded Fillet Joints

B.1 Calculation of the strength of fillet welds includes the determination of the design breaking force

Estimated breaking force F p , N, is determined by the formula

Where F p - calculated breaking force, N;

W- moment of resistance in the direction of load application, mm 3, equal to J / e, where J- moment of inertia of the profile section, mm 4, set in the manufacturer's technical documentation;

σ min - the value of the minimum breaking stress, σ min 37 MPa;

a- distance between the axes of rotation, a= 400 mm (Figure 3);

e- the distance from the neutral axis of the profile to the critical line, determined from the section drawing of the profile.

Geometric parameters for calculating the breaking force F p are shown in Figure 3.

C.2 The manufacturer's technical documentation shall contain the values of the calculated breaking force of welded joints of all profile assemblies provided by the manufacturer's profile system.

Input control of raw materials in production is carried out by taking samples from each batch of raw materials.

Input control is carried out according to the following parameters:

Humidity;

Bulk density;

flowability;

The presence of foreign inclusions;

Particle size.

Control results are processed and stored according to 6.1.5.
