This document specifies a constant-stress flexometer test for the determination of the temperature rise
and resistance to fatigue of vulcanized rubbers.
Many rubber products, such as tyres and belts, are tested by subjecting them to an oscillating load with
a constant peak stress amplitude. In order to obtain good correlation between accelerated tests and
in-service exposure of these products, this document gives instructions for carrying out measurements
under such conditions.
This method is not applicable for rubber having a hardness greater than 85 IRHD.
