Standard Test Method for Rubber From Natural Sources—Plasticity Retention Index (PRI)

Importancia y uso:

4.1 This test method may be used to evaluate the heat and/or oxidation stability (aging) of raw rubber under controlled conditions. High original and aged plasticity values usually correspond to good aging properties. The ratio of the aged to original plasticity values expressed as a percentage, the PRI, is used as an indication of aging.
