英文名称：Plastics — Acquisition and presentation of comparable multipoint data — Part 3: Environmental influences on properties

标准范围

本文件规定了多点数据采集和呈现的测试程序，这些数据证明了塑料在以下环境下的行为:-？长时间暴露在高温下；-？液体化学品；-？恒定拉伸应力下的环境应力开裂；-？人工风化。这些测试按环境严重程度的增加顺序列出。通过首先在最不严重的环境下进行测试，可以对更严重条件下的测试是否值得做出明智的判断。

This document specifies test procedures for the acquisition and presentation of multipoint data which demonstrate the behaviour of plastics under the following environments:—    prolonged exposure to heat;—    liquid chemicals;—    environmental stress cracking under a constant tensile stress;—    artificial weathering.The tests are listed in order of increasing severity of the environment. By testing under the least severe environments first, it is possible to make informed judgements regarding whether tests under more severe conditions are worthwhile.
