6 Control methods
6.1 Sampling
Rolls of tape are selected in the volume indicated in Table 3.
6.2 Selected rolls are conditioned at a temperature of (23±5) °C for at least 24 hours.
After holding, at least 3 m of tape is unrolled from each roll smoothly, without jerking, after which samples are prepared for subsequent tests.
Before testing for compliance with the requirements of 4.4.2, rolls must be conditioned in accordance with GOST 6433.1 under the following conditions: 24 hours (15-35C) 45-75%.
6.3 Voltage test 1 without breakdown is carried out under conditions M (15-35C) 45-75%.
All other tests are carried out indoors at a temperature of (23±5) °C.
6.4 The appearance of the tape is assessed visually.
6.5 Sizing
6.5.1 The outer diameter of the roll and the width of the tape are measured with a metal ruler in accordance with GOST 427 with a division value of 1 mm and a measurement limit of up to 1000 mm, a tape measure in accordance with GOST 7502, 3rd class with an upper measurement limit of 5 m or a caliper with a division value of vernier 0 .1 mm according to GOST 166.
6.5.2 The thickness of the tape is measured with a thickness gauge according to GOST 11358 with a measurement limit of 10 mm, a division value of 0.01 mm with a standardized measuring force.
A sample with a length of (200±2) mm is cut from each roll, folded into four layers and compressed by rolling a roller weighing (5.00±0.05) kg without pressing at least three times in the forward and reverse directions along the length.
Measurements are carried out at at least three points of each sample folded into four layers.
The result is taken as the arithmetic mean of all measurements of all samples, divided by 4 (the number of layers).
The result is calculated to the third decimal place and rounded to the second decimal place.
6.5.3 The length of the tape in a roll is measured with a meter counter with a measurement limit of 10 m, a division value of 0.5 m, and a measurement error of ±0.5%.
6.6 Determination of stickiness

6.6.3 Test performance
6.6.3.1 The single-sided tape is bent in half widthwise so that the rubber layer is inside.
When testing double-sided tape, the sample is cut in half widthwise and the pieces are folded so that the outer side of the tape overlaps the inner.
The prepared tape is rolled on a flat, smooth surface with a roller without pressure at least three times in the forward and reverse directions along a length of (150 ± 1) mm, leaving the ends of the tape with a length of (50 ± 1) mm unglued on one side.
6.6.3.2 The unglued ends of the tape are secured in clamps. Weights are installed on the lower clamp platform, the mass of which is selected depending on the width of the tape in accordance with Table 4.
Table 4
Tape width, mm | Weight mass, g |
|
before the tape ages | after tape aging |

If unsatisfactory results are obtained, the test is repeated using twice the number of rolls of tape. The results of the re-inspection apply to the entire batch.
6 Control methods
6.2 Selected rolls are conditioned at a temperature of at least 24 hours.
After holding, at least 3 m of tape is unrolled from each roll smoothly, without jerking, after which samples are prepared for subsequent tests.
Before testing for compliance with the requirements of 4.4.2, rolls must be conditioned in accordance with GOST 6433.1 under the following conditions: 24 hours (15-35C) 45-75%.
6.3 Voltage test 1 without breakdown is carried out under conditions M (15-35C) 45-75%.
All other tests are carried out indoors at a temperature of .
6.4 The appearance of the tape is assessed visually.
6.5 Sizing
6.5.1 The outer diameter of the roll and the width of the tape are measured with a metal ruler in accordance with GOST 427 with a division value of 1 mm and a measurement limit of up to 1000 mm, a tape measure in accordance with GOST 7502, 3rd class with an upper measurement limit of 5 m or a caliper with a division value of vernier 0 .1 mm according to GOST 166.
6.5.2 The thickness of the tape is measured with a thickness gauge according to GOST 11358 with a measurement limit of 10 mm, a division value of 0.01 mm with a standardized measuring force.
A sample mm long is cut from each roll, folded into four layers and compressed by rolling a roller weighing kg without pressure at least three times in the forward and reverse directions along the length.
Measurements are carried out at at least three points of each sample folded into four layers.
The result is taken as the arithmetic mean of all measurements of all samples, divided by 4 (the number of layers).
The result is calculated to the third decimal place and rounded to the second decimal place.
6.5.3 The length of the tape in a roll is measured with a meter counter with a measurement limit of m, a division value of 0.5 m, and a measurement error of .
6.6 Determination of stickiness
6.6.1 Two samples of tape, mm long, are cut from each roll, one of which is tested before aging, and the other after aging.

6.6.3 Test performance
6.6.3.1 The single-sided tape is bent in half widthwise so that the rubber layer is inside.
When testing double-sided tape, the sample is cut in half widthwise and the pieces are folded so that the outer side of the tape overlaps the inner.
The prepared tape is rolled on a flat, smooth surface with a roller without pressure at least three times in the forward and reverse direction along the length of mm, leaving the ends of the tape with a length of mm unglued on one side.
6.6.3.2 The unglued ends of the tape are secured in clamps. Weights are installed on the lower clamp platform, the mass of which is selected depending on the width of the tape in accordance with Table 4.
Table 4
Mark and measure with a metal ruler the length of the section of the tape where delamination occurred within 1 minute from the moment the weights were installed.
The stickiness of the tape after aging is determined by first keeping the samples for 16 hours in a thermostat at a temperature and then cooling them for an hour at a temperature.
