标准摘要
[中文适用范围]： 本文件规定了一种基于测量裂纹尺寸随暴露时间的变化来确定水环境（包括大气暴露）中小表面裂纹的生长速率的方法。 该方法可应用于应力腐蚀和腐蚀疲劳裂纹扩展。 它还描述了生成裂纹前体的各种方法，包括加速生成单凹坑。 本文件所涉及的行业包括发电（包括核能）、石油和天然气、航空航天和汽车。 [外文原描述]： This document specifies a method for determining the growth rate of small surface cracks in an aqueous environment (including atmospheric exposure) based on measurement of the change in size of the crack with exposure time. The methodology can be applied to stress corrosion and corrosion fatigue crack propagation. It also describes the varied methodologies for the generation of crack precursors including accelerated generation of single pits. Industries for whom this document is relevant include power generation (including nuclear), oil and gas, aerospace and automotive.
