ISO 7539-12:2023

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.
