Caoutchouc naturel brut — Détermination de l'indice de rétention de plasticité (PRI)

Abstract / scope

Cancels and replaces the second edition (1981). 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.
