Rubber, vulcanized - Determination of low-temperature characteristics - Temperature-retraction procedure (TR test)
This document specifies a method for the determination of the temperature-retraction characteristics of stretched vulcanized rubber. This document does not cover thermoplastic rubbers, as many thermoplastic elastomers have a yield point in the range of 5 % to 20 % elongation.

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.
With Requirements, quickly access the main part of the normative text!
At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.
