Caoutchouc acrylonitrile-butadiène (NBR) — Méthode d'évaluation

This document specifies, for acrylonitrile-butadiene rubbers (NBRs):

— physical and chemical tests on raw rubbers;

— standard materials, a standard test formulation, equipment and processing methods for evaluating the vulcanization characteristics.

The mixing preferred method is the single stage mixing with LIM (laboratory internal mixer).
