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.
