ECSS-Q-ST-70-38C – High-reliability soldering for surface mount and mixed technology (31 July 2008)


This document defines the requirements for the evaluation of the susceptibility of the SCC resistance.

It 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 can be submitted for inclusion into the various tables contained in ECSS‐Q‐ST‐70‐36.

In this document, the supplier is identified as the entity that performs the test.
This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS‐S‐ST‐00.
