3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 1968 apply.
4 Designation
Fibre ropes shall be designated by
— the words “fibre rOpe”,
— the number of this International Standard,
— the construction or type of rope (see Clause 5).
— the reference number of the rope,
— the material from which the rope is made (the mixing of polyamide fibre types and grades shall not be permitted), and
— the type of stabilization (1 or 2 in accordance with ISO 9554).
Polyamide-laid ropes that are required to have a heat setting on the rope to ensure lay and dimensional stability are designated as type 1 ropes. In other cases. polyamide-laid ropes that are not required to have a heat setting on the rope are designated as type 2 ropes.
EXAMPLE
Designation of a 3-strand hawser-laid rope heat set (type 1), reference number 20 (type A), corresponding to a linear density of 247 ktex and made of polyamide (PA):
