Scope

This International Standard 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.
The linear density, lay length and braid pitch are measured with the rope under a specified tension called the
reference tension, as specified in Annex A.
The elongation corresponds to the measured increase in length of the rope when the tension to which it is
subjected is increased from an initial value (reference tension) to a value equal to 50 % of the minimum
specified breaking strength of the rope.
The breaking force is the maximum force registered (or reached) during a breaking test on the test piece,
carried out on a tensile testing machine with constant rate of traverse of the moving element. The breaking
force values given in the tables of rope specifications are only valid when this type of testing machine is used.
When it is not possible to test the rope in full size, the method described in Annex B can be used, subject to
agreement between the parties involved.
