Rubber, vulcanized - Determination of temperature rise and resistance to fatigue in flexometer testing - Part 3: Compression flexometer (constant-strain type) - Third Edition
N 4666-3
Annotation
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 recommended for rubber having a hardness greater than 85 IRHD.

Резина, вулканизировавшая - Определение повышения температуры и сопротивления усталости в испытании флексометра - Часть 3: флексометр Сжатия (тип постоянного напряжения) - Третий Выпуск
Этот документ указывает тест флексометра с амплитудой постоянной деформации для определения повышения температуры и сопротивления усталости вулканизировавшей резины. Указанный флексометр известен как флексометр Гудрича, но любой другой аппарат, дающий эквивалентную производительность, может использоваться.
