This document specifies the minimum requirements to qualify the materials and processes selected to provide corrosion protection. Additional testing can be performed to satisfy the requirements for materials and processes used in specific flight applications. This standard specifies the behavior of metals and alloys but it does not remove the responsibility for the degradation of other materials such as polymers or ceramics to be considered. This standard refers only to metallic materials.
This document does not cover the requirements for protection against stress corrosion cracking (SCC) which has its own dedicated standard ECSS-Q-ST-70-36. It covers typical spacecraft and launcher programs on ground for a period of no more than 10 years.
This standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.
