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.
