粘合剂.胶粘件试验用标准实验室老化条件的选择指南

[中文适用范围]： 本国际标准描述了粘合接头可能暴露于各种环境影响（气候或化学）的实验室老化条件，目的是评估这些影响对某些性能的影响。 老化条件适用于粘合组件并且可用于构成用于评估粘合剂的一组测试。 使用本国际标准中描述的程序获得的结果不一定适用于粘合组件使用寿命的确定，因为测试结果与粘合组件在使用一段时间内的行为之间没有直接关系状况。 然而，对于某些特定应用，程序经验可能能够建立相关性。 注：老化条件最好与粘合剂的具体应用相关。 [外文原描述]： ISO 9142:2003 describes laboratory ageing conditions under which adhesive joints may be exposed to various environmental influences -- climatic or chemical -- for the purpose of assessing the effects of such influences on certain properties. The ageing conditions are applicable to bonded assemblies and may be used to constitute a set of tests for the evaluation of an adhesive. The results obtained using the procedures described in this International Standard are not necessarily applicable to the determination of the service life of a bonded assembly because there is no direct relation between the test results and the behaviour of a bonded assembly over a period of time under service conditions. However, for certain specific applications, experience with the procedures may enable a correlation to be established.
