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.
