ECSS-Q-70-37A – Determination of the susceptibility of metals to stress-corrosion cracking (20 January 1998)

This Standard has been cancelled and replaced by ECSS-Q-ST-70-37C (15 November 2008).


This document defines the preferred way to determine the susceptibility of metals and weldments to stress–corrosion cracking by alternate immersion in 3,5 % sodium chloride under constant load.

The results obtained from test programmes made according to this specification are used to classify alloys, weldments and their individual heat treatment conditions. When sufficient stress-corrosion data exists the alloy designations may be submitted for inclusion into the various tables contained in ECSS-Q-70-36.
