标准摘要
[中文适用范围]: 本文件规定了根据长期暴露于高温的结果来评估橡胶耐热性的原则和程序。规定了两种方法(见简介): — 一种使用阿伦尼乌斯方程; — 另一种使用 WLF 方程。在本文件中,耐热性的评估完全基于暴露于高温一段时间后所选属性的变化。橡胶的各种属性在热老化时会以不同的速率变化,因此只能使用相同的属性来比较不同的橡胶。 [外文原描述]: This document specifies the principles and procedures for estimating the thermal endurance of rubbers from the results of exposure to elevated temperatures for long periods. Two approaches are specified (see Introduction): — one using the Arrhenius equation; — the other using the WLF equation. In this document, the estimation of thermal endurance is based solely on the change in selected properties resulting from periods of exposure to elevated temperatures. The various properties of rubbers change at different rates on thermal ageing, hence comparison between different rubbers can only be made using the same properties.
英文名称Rubber, vulcanized or thermoplastic — Estimation of life-time and maximum temperature of use
