(Changed edition, Rev. No. 2).

5.6. Sampling for mechanical test on a cold draught — GOST 7564.

5.7. The test sediment in a cold condition of hot-rolled steel up to 30 mm, grooved, hot-rolled and calibrated with special surface finish size up to 28 mm is carried out according to GOST 8817. Rental of steel grades 10, 15, 20, 20kp, and 25 group 66 cold-worked condition, not pass a test in sediment up to ¹/₃, is subjected to a repeated test up to ¹/₂.

Rent with size over 30 mm feel the upsetting according to the method approved in the prescribed manner.

On the territory of the Russian Federation there are PR 50.2.009−94.

5.8. Control of mechanical properties is carried out according to GOST 1497 on samples of five times the round length with a diameter of 10 mm. is allowed to conduct tests on full-scale samples.

5.7, 5.8. (Changed edition, Rev. No. 2).

5.9. Depth bezoperatsionnogo layer was determined by M according to GOST 1763.

5.10. The grain size is determined according to GOST 5639.

5.11. Assessment grouplisting perlite is carried out according to GOST 8233.

Evaluation of granular perlite is carried out according to agreed standards.

(Changed edition, Rev. No. 2).

5.12. The hardness is determined according to GOST 9012.

5.13. Non-metallic inclusions is determined according to GOST 1778.

5.14. Allowed to apply non-destructive and statistical control methods according to the methods agreed in the prescribed manner.

6. MARKING, PACKAGING, TRANSPORTATION AND STORAGE

6.1. Packing, marking, transportation and storage rolled produced as per GOST 7566 with the following additions: marking, packaging, transportation and storage of the calibrated hire must meet the requirements of GOST 1051, rolled with special surface finish GOST 14955.

Label, calibrated, and calibrated with special surface finish applied to hire additional letters «XB» (cold heading).

The outer diameter of a coil of hot-rolled steel should be not more than 1500 mm, the inner is not less than 180 mm.

Transportation can be done at indoor and outdoor vehicles of all types in accordance with the rules of cargo transportation applicable to the transportation of the species.

Weight of cargo must not exceed when mechanized loading into open vehicles is 10 tons, covered — 1,25 t.

When transporting in a single address two or more parcels, the dimensions of which allow it to form a transport package with dimensions according to GOST 24597, the package needs to be formed into transport packets according to NTD.

The uld (linkage stack) — according to GOST 7566.
