1.1本规程涵盖了在开发用于预测建筑构件和材料使用寿命的加速试验时应遵循的步骤。虽然没有详细描述预测使用寿命所需的数学分析，但可以使用确定性或概率分析。 注1:比较测试是本实践中确定的步骤的替代方法；当暴露在相同条件下时，它涉及将测试组件或材料的结果与类似控制组件或材料的结果进行定性比较。 1.2本规程概述了使用寿命预测的系统方法，包括识别所需信息、开发加速试验、解释数据和报告结果。

1.1 This practice covers steps that should be followed in developing accelerated tests for predicting the service life of building components and materials. Although mathematical analyses needed for prediction of service life are not described in detail, either deterministic or probabilistic analysis may be used. Note 1-Comparative testing is an alternative to the steps identified in this practice; it involves qualitative comparison of the results of a test component or material with the results of a similar control component or material when exposed to identical conditions. 1.2 This practice outlines a systematic approach to service life prediction, including the identification of needed information, the development of accelerated tests, the interpretation of data, and the reporting of results.
