Rubber, raw natural — Determination of plasticity retention index (PRI)

ISO 2930:2009 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.
