ISO 2307:2004 specifies, for ropes of different kinds, a method of determining each of the following characteristics: linear density, lay length, braided pitch, elongation, and breaking force. The linear density, lay length and braided pitch are measured with the rope under a specified tension called the reference tension. ISO 2307:2004 also provides a method for measuring water repellency, lubrication and finish content and heat setting treatment when requested by the customer.
