Notes:

1. The ropes, breaking strength of which is given to the left of the bold line are made of wire without coating and galvanized. Ropes of galvanized wire groups W and coolant diameter 40.5 and 45.5 mm marking groups 1370 N/mm² (140 kgf/mm²), 34,0−38,0 mm marking group 1470 N/mm² (150 kgf/mm²) and 25.5−38.0 mm marking groups 1570 N/mm² (160 kgf/mm²) of 25.0−31.5 mm marking group 1670 N/mm² (170 kgf/mm²), Of 17.5−27.5 mm marking group 1770 N/mm² (180 kgf/mm²), 8,6−14,0 mm marking group 1960 N/mm² (200 kgf/mm²) are made by agreement between manufacturer and consumer.

The ropes, breaking strength of which is given to the right of the bold line are made of wire without coating. Allowed in coordination with the consumer manufacturing of ropes, galvanized wire.

2. The diameters of the ropes over 10mm rounded to whole numbers or to 0.5 mm.
