发布日期：2023-11

标准范围

本文件规定了设计和进行试验的一般要求，以评估金属和合金在大气暴露条件下对应力腐蚀开裂的敏感性。测试方法包括暴露于自然环境和人工加速实验室测试中的环境。应用包括航空航天和建筑中的铝及其合金；建筑、压力容器和核废料密封中的不锈钢；汽车、建筑和起重链中的高强度低合金钢。

This document specifies the general requirements for designing and conducting tests to assess the susceptibility of metals and alloys to stress corrosion cracking under atmospheric exposure conditions.

The testing methodology includes exposure to natural environments and environments in artificially accelerated laboratory tests.

Applications include aluminium and its alloys in aerospace and construction; stainless steels in construction, pressure vessels, and nuclear waste containment; high strength low alloy steels in automotive, construction, and in lifting chains.
