标准范围

ISO 4666-3:2010规定了用于测定硫化橡胶温升和抗疲劳性的恒应变振幅挠曲计试验。规定的挠度计称为Goodrich挠度计，但可使用任何其他具有同等性能的仪器。ISO 4666-3:2010给出了进行测量的说明，这些测量可以预测在使用中受到动态弯曲的成品中橡胶的耐久性，如轮胎、轴承、支架、V型皮带和电缆滑轮插入环。然而，由于使用条件的广泛变化，ISO 4666各部分中描述的加速试验与使用性能之间不存在简单的相关性。对于硬度大于85 IRHD的橡胶，不建议使用该方法。

ISO 4666-3:2010 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 4666-3:2010 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 ISO 4666 and service performance can be assumed.The method is not recommended for rubber having a hardness greater than 85 IRHD.
