WARNING — Persons using this International Standard should be familiar with normal laboratorypractice. This standard does not purport to address all of the safety problems, if any, associated withits use. It is the responsibility of the user to establish appropriate safety and health practices and toensure compliance with any national regulatory conditions.CAUTION — Certain procedures specified in this International Standard may involve the use orgeneration of substances, or the generation of waste, that could constitute a local environmentalhazard. Reference should be made to appropriate documentation on safe handling and disposal after use.This part of ISO 4666 specifies the flexometer test with constant-strain amplitude for the determination of thetemperature rise and resistance to fatigue of vulcanized rubber. The flexometer specified is known as theGoodrich flexometer, but any other apparatus giving equivalent performance can be used.This part of ISO 4666 gives directions for carrying out measurements which make possible predictionsregarding 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 serviceconditions, no simple correlation between the accelerated tests described in the various parts of thisInternational Standard and service performance can be assumed.The method is not recommended for rubber having a hardness greater than 85 IRHD.
