标准范围

ISO 4666-4:2007规定了用于测定硫化橡胶温升和抗疲劳性的恒定应力挠曲试验。许多橡胶制品，如轮胎和皮带，都是通过将它们置于具有恒定峰值应力振幅的振荡载荷下进行试验的。为了在加速试验和这些产品的运行暴露之间获得良好的相关性，ISO 4666的本部分给出了在此类条件下进行测量的说明。对于硬度大于85 IRHD的橡胶，不建议使用此方法。

ISO 4666-4:2007 specifies a constant-stress flexometer test for the determination of the temperature rise and resistance to fatigue of vulcanized rubbers.Many rubber products, such as tyres and belts, are tested by subjecting them to an oscillating load with a constant peak stress amplitude. In order to obtain good correlation between accelerated tests and in-service exposure of these products, this part of ISO 4666 gives instructions for carrying out measurements under such conditions.This method is not recommended for rubber having a hardness greater than 85 IRHD.
