标准摘要
[中文适用范围]： 本文件规定了多种测定硫化或热塑性橡胶试件在恒定伸长率或恒定负载下相对较短的拉伸负载期间和之后的尺寸变化的方法。 恒定伸长试验旨在测量橡胶在标准实验室温度下拉伸至指定应变后保持其弹性性能的能力，该应变在相同温度或指定较高温度下保持指定时间，然后释放在测试温度或标准实验室温度下。 恒载试验规定了在标准实验室温度下承受恒载的橡胶的伸长率、蠕变和张力永久变形的测定方法。 该测试方法旨在测量硬度范围为 20 IRHD 至 94 IRHD 的橡胶的弹性性能。 蠕变测量不适用于产品设计或低蠕变材料的评估。 对于这些，ISO 8013 适用，并且该测试的结果与注释的结果之间没有一致。 恒负载测试主要用于薄壁产品的固化状态测量和质量控制。 固化状态或交联度的提高通常反映在凝固、蠕变或伸长率的降低上。 [外文原描述]： This document specifies a number of methods of determining the dimensional changes in test pieces of vulcanized or thermoplastic rubber during and after tensile loading for relatively short periods under constant elongation or constant loading. The constant-elongation test is intended to measure the ability of rubbers to retain their elastic properties after extension, at a standard laboratory temperature, to a specified strain which is maintained for a specified time at the same or at a specified higher temperature and then released at the test temperature or at the standard laboratory temperature. The constant-load test specifies a method for the determination of elongation, creep and tension set of rubbers subjected to a constant load at standard laboratory temperature. The test methods are intended to measure the elastic properties of rubber in the hardness range 20 IRHD to 94 IRHD. The creep measurement is not intended for product design or the evaluation of low-creep materials. For these, ISO 8013 applies, and there is no agreement between the results of this test and those of ISO 8013. NOTE The constant-load test is primarily intended for the measurement of state of cure and the quality control of thin-walled products. An increase in the state of cure or degree of crosslinking is usually reflected in a decrease in set, creep or elongation.
