The length of the tape in a roll to select the number of measurement points in the coil is determined by the formula given in claim 4.2.

The number of monitored points in each selected coil is determined in accordance with table.3.

Selected roll of tape is considered valid if the number of measurement results that do not meet the requirements of table.1, less than the acceptance number given in table.3.

If unsatisfactory result on one of the selected coils controlled by each roll of the party.

Allowed the manufacturer to monitor each roll of the party and to carry out thickness control in the production process.

(Added, Rev. N 3).

3.3. For the tensile test taken three rolls from the party.

3.4. To determine the chemical composition selected from the party two rolls.

On the manufacturer sampling for determining the chemical composition of a molten metal or the ingot or billet during the formation of the party.

3.5. If unsatisfactory test results of at least one of the indicators (except the thickness) it is carried out re-testing at twice the sample taken from the same batch.

The results of repeated tests apply to the entire party.

(Changed edition, Rev. N 1, 3).

4. TEST METHODS

4.1. The surface quality of the test strips without the use of magnifying devices.

The presence of burrs on the strip edges checked visually.

4.2. The thickness of the tape measure with a micrometer type PR GOST 4381 division value of 0.002 mm.

The measurement of the thickness of the tape is carried out at a minimum distance of 1 m from the end and not less than 5 mm from the edge.

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

The results of measuring thicknesses that do not meet the requirements of table.1, should not differ from the permissible by more than half of the tolerance field.

The tape length per roll (ГОСТ 16358-79 Ленты медные для коаксиальных магистральных кабелей. Технические условия (с Изменениями N 1, 2, 3)) in meters is calculated by the formula
