This document specifies, for ropes of different kinds, a method of determining each of the following characteristics:
— linear density;
— diameter;
— lay length;
— braid pitch;
— elongation;
— breaking force.
This document also provides a method for measuring water repellence, lubrication and finish content, when requested by the customer.
