ISO 2578:1993 塑料.暴露于长期热作用的时间和温度极限的测定

标准编号：ISO 2578:1993

中文名称：塑料.暴露于长期热作用的时间和温度极限的测定

英文名称：Plastics — Determination of time-temperature limits after prolonged exposure to heat

发布日期：1993-08

标准范围

规定了评估长期高温下塑料耐热性能的原则和程序。对热老化的研究仅基于暴露在高温下一段时间后某些性能的变化。所研究的性能总是在温度恢复到环境温度后进行测量。

Specifies the principles and procedures for evaluating the thermal endurance properties of plastics exposed to elevated temperature for long periods. The study of the thermal ageing is based solely on the change in certain properties resulting from a period of exposure to elevated temperature. The properties studied are always measured after the temperature has returned to ambient.
