______________
* On the territory of the Russian Federation GOST R 50779.71.

The selection of rolls of tapes in the sample is carried out «blindly» (by the greatest objectivity) according to GOST 18321.

If the quantity does not exceed three coils, checked each roll of ribbons.

5.3 the Number selected to control the thickness of the coils of strips is determined in accordance with table 4.


Table 4 — Number selected to control the thickness of the coils tapes

In pieces

The number of monitored points in each selected coil is determined depending on the length of the tape in the coil in accordance with table 5.


Table 5 — Number of monitored points in each selected coil

The length of the tape in a roll to select the number of measurement points in the coil is determined by the formula (1) given in 6.3.

Selected roll of tape is considered valid if the number of measurements that meet the requirements of table 1, less than the acceptance number given in table 5.

5.4 To control the width, appearance, and camber of the party selected coils in accordance with table 6.

6.1 control the size, appearance, and camber is carried out with a given probability 96% (acceptance level of defects AQL=4%).

6.2 appearance of the tapes checked by inspection without the use of magnifying devices.

6.3 the Thickness of the tape is measured with a micrometer according to GOST 6507 or lever micrometer churchyard 4381.

The measurement of the thickness of the tape is carried out at a distance of not less than 10 mm from edges and not less than 100 mm from the end of the tape. For tapes with a width of 20 mm or less, the measurement is performed in the middle of the tape.

The thickness of the strip measured at each selected coil to points positioned uniformly randomly along the length of the roll.

The tape length , m, is calculated by the formula

, (1)

where and  — respectively the outer and inner diameters of the coil, measured with a ruler according to GOST 427, mm.

 — tape thickness, mm.

6.4 the width of the tape measure with a metal ruler according to GOST 427, caliper churchyard 166 or metal measuring tape according to GOST 7502.

The measurement is carried out in a single place at a minimum distance of 100 mm from the end.

6.5 Camber of the tape measure according to GOST 26877 in one place on any area of the roll.

6.6 Waviness of the strip edges check bending it around a mandrel with a diameter of 100−120 mm. If the ripple does not disappear, the roll of tape is rejected.

6.7 Selection of samples for tensile tests carried out according to GOST 24047.
