Fibre ropes - Determination of certain physical and mechanical properties

ISO 2307:2010 specifies, for ropes of different kinds, a method of determining each of the following characteristics: linear density; lay length; braid pitch; elongation; breaking force. The linear density, lay length and braided pitch are measured with the rope under a specified tension called the reference tension. 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. ISO 2307:2010 also provides a method for measuring water repellency, lubrication and finish content, and heat setting treatment, when requested by the customer.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
