Organization: ISO
Publication Date: 1 August 2017
Status: active
Page Count: 14
ICS Code (Latex and raw rubber): 83.040.10
scope:

This document specifies a method for determining the plasticity retention index (PRI) of raw natural rubber.

The PRI is a measure of the resistance of raw natural rubber to thermal oxidation. A high resistance to thermal oxidation is shown as a high value of the index. PRI is not an absolute value and cannot give an absolute classification of plasticity number of different natural rubber after oxidation.
