NF ISO 4666-3
Rubber, vulcanized - Determination of temperature rise and resistance to fatigue in flexometer testing - Part 3 : compression flexometer (constant-strain type)
ISO 4666-3:2016 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.ISO 4666-3:2016 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 recommended for rubber having a hardness greater than 85 IRHD.

Le présent document spécifie une méthode d'essai au flexomètre à compression pour déterminer l'élévation de température et de la résistance à la fatigue du caoutchouc vulcanisé. Les résultats d'essais permettent de donner des prévisions concernant la durabilité des caoutchoucs dans des produits finis soumis à des flexions dynamiques en service, tels que pneumatiques, paliers, appuis, courroies trapézoïdales et garnitures annulaires de poulies pour câbles.
