The results of repeated tests spread to the entire party.

3. CONTROL METHODS

3.1. The surface of the strip inspected without the use of magnifying devices.

3.2. The thickness of the strip is measured with a micrometer according to GOST 6507, measuring the pressure head GOST 28798 or indicator according to GOST 9696.

The thickness of the strip and of the tape measure at a minimum distance of 100 mm from the end and not less than 10 mm from the edge. For tapes with a width of 200 mm and less, the measurement is carried out in the middle.

The thickness of the strip control statistical method to ensure the specified thickness of the strip with a probability of 96% (=4%).

The thickness of the strip measured at each selected strip, or at each selected roll of tape at points located uniformly randomly on the perimeter of the strip or along the length of the roll.

The number of bands in the party () is calculated by the formula

,

where the weight of the batch, kg;

 — strip thickness, mm;

 — band width, mm;

the length of the strip, mm;

 — material density, g/cm.

Number of controlled sections in the band () is calculated by the formula

.

The results of measuring the thickness of the band, not the corresponding table.1 and 3, shall not differ from the permissible by more than half, the maximum deviations.

The tape length () m to select the number of controlled points in the roll on the table.9 is calculated by the formula

,

where and  — respectively the outer and the inner diameter of the coil measured by the ruler according to GOST 427, mm.

 — tape thickness, mm.

The results of measuring thicknesses that do not meet the requirements of table.5, should not differ from the permissible by more than half, the maximum deviations of the tapes.

3.3. The width of the strip measured by Vernier caliper according to GOST 166, length, and Squareness (cosine of the cut) strips and the length of the tape — measuring tape according to GOST 7502.

The width of the ribbon and strip are measured at three sites:

both ends and in the middle of three measurements in each plot at a distance of not less than 1 m from one another.

3.4. Allowed the manufacturer to control the thickness, width, and Squareness of the strip other means of measurement, to ensure the necessary accuracy. In case of disagreement, the evaluation was carried out by the method specified in the standard.

3.5. Camber strips are measured according to GOST 26877 on any portion of the tape.

Camber can be measured by another method to ensure the required measurement accuracy. In case of disagreement in the evaluation of camber, it is carried out according to GOST 26877.

3.6. The deflection of the strips is measured according to GOST 26877 once at any polling station selected band.

3.7. For tensile testing from each selected strip or selected each roll of strips cut one sample in the direction of rolling. The selection of samples for testing tensile — according to GOST 24047.

Tensile test of a strip not thicker than 3 mm is carried out on flat samples of type I or type II, with a width of 10 mm () with an initial estimated length () 5,65 churchyard 11701.

Tensile test strips of a thickness of 3 mm and more is carried out according to GOST 1497 on flat samples of type I and type II width of 20 mm for strips with thickness up to 7 mm inclusive and a width of 30 mm for strips of a thickness more than 7 mm. the calculated Initial length of samples () is equal to 5,65 .

Allowed tensile test carry out according to GOST 11701 for strips with thickness up to 0.5 mm inclusive at a flat samples having a width of 12.5 mm with an initial estimated length of 4, for strips and strips of a thickness more than 0.5 to 2.8 mm inclusive of flat samples with width equal to 20 mm, with an initial estimated length equal to 11,

3 .

3.8. To analyze the chemical composition of each selected strip or selected each roll of ribbon is cut on the same model. Selection and preparation of samples for determining the chemical composition — GOST 24231.

Chemical composition analysis is carried out according to GOST 15027.1 — 15027.4 GOST and GOST 15027.12 or by other methods providing the required accuracy set by the standard.

The differences in the evaluation of the chemical composition analysis is carried out according to GOST 15027.1 — 15027.4 GOST and GOST 15027.12.

4. TRANSPORTATION AND STORAGE

4.1. Strip and ribbon transporterowych all types of transport in covered vehicles in accordance with cargo carriage regulations applicable to transport of this species.

4.2. It is allowed to transport and strip of containers according to GOST 18477 and GOST and GOST 15102 20435 or carload shipments in the packaged form without packaging in boxes.

4.3. Strips and ribbons are kept indoors in uncompressed form in conditions that ensure their safety. Under these conditions, the storage of consumer properties of the strip in storage is not changed.
