标准摘要
[中文适用范围]： 本文件规定了用于测定硫化橡胶的温升和抗疲劳性能的恒应变幅屈曲试验。 指定的屈曲计被称为 Goodrich 屈曲计，但可以使用具有同等性能的任何其他装置。 本文件提供了进行测量的指导，这些测量可以预测在使用中承受动态弯曲的成品中橡胶的耐久性，例如轮胎、轴承、支架、V形皮带和电缆滑轮插入环。 然而，由于使用条件的巨大差异，不能假设本文件各个部分中描述的加速测试与使用性能之间存在简单的相关性。 该方法不适用于硬度大于 85 IRHD 的橡胶。 [外文原描述]： 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.
