trademark or the name and trademark of manufacturer;

name of the organization, which includes the manufacturer;

the number of the rope on the numbering system of the manufacturer;

the symbol of the rope;

the length of the rope;

the gross weight of the rope;

the total breaking strength of all wires in the rope or breaking strength of the rope as a whole;

(Changed edition, Rev. N 1).

3.2. Appearance, dimensions and mechanical properties of the wires, check each wire.

3.3. Other rules of acceptance GOST 3241.

4. TEST METHODS

4.1. To check the mechanical properties of wires and diameter of wires, the presence of lubricant in the rope and the core from each rope selected segment of the rope length of at least 1 m.

From cut the rope to tensile tests, twisting and kinking of the 46 selected core wires of the strands (including 27 of the wires of the outer layer of strands 18 and wires of the inner layers and 1 Central wire), and from the rope with a metal core wires 12 of the metal core.

4.2. The mechanical properties of the wires and marking group of the rope is determined by the test breaking strength of wire rope.

If the total breaking strength of all wires of the rope will be below the breaking strength shown in table.1 and 2, we conducted a second test, the results of which are final.

During the test of the breaking strength of rope of grade 1 is generally allowed to evaluate the brand of the rope on the test results of mechanical properties of 10% of the wires of each diameter, but not less than three. The number of wires, obtained by the calculation is rounded to the nearest whole number upward.

4.3. The presence of lubricant in the rope and the core check visual control.

4.4. Other requirements for test methods — according to GOST 3241.
