BS ISO 4666-3:2022 Rubber, vulcanized. Determination of temperature rise and resistance to fatigue in flexometer testing. Compression flexometer (constant-strain type)
1 Scope
This document specifies the flexometer test with constant-strain amplitude for the
determination of the temperature rise and resistance to fatigue of vulcanized rubber.
The flexometer specified is known as the Goodrich flexometer, but any other apparatus
giving equivalent performance can be used.
This document gives directions for carrying out measurements which make possible predictions
regarding the durability of rubbers in finished articles subject to dynamic flexing
in service, such as tyres, bearings, supports, V-belts, and cable-pulley insert rings.
However, owing to the wide variations in service conditions, no simple correlation
between the accelerated tests described in the various parts of this document and
service performance can be assumed.
The method is not intended for rubber having a hardness greater than 85 IRHD.
