ECSS-Q-ST-70-17C – Durability testing of coatings (1 February 2018)


This standard specifies requirements for the durability testing of coatings most commonly used for space applications, i.e.:

  • Thin film optical coatings
  • Thermo-optical and thermal control coatings (the majority are paints, metallic deposits and coatings for stray light reduction)
  • Metallic coatings for other applications (RF, electrical, corrosion protection)

This standard covers testing for both ground and in-orbit phases of a space mission.

This standard includes coatings within off-the-shelf items

This standard specifies the types of test to be performed for each class of coating, covering the different phases of a space project (evaluation, qualification and acceptance)

This standard does not cover:

  • The particular qualification requirements for a specific mission
  • Specific functional testing requirements for the different coating classes
  • Test requirements for long term storage
  • Solar cell cover glass coatings
  • Surface treatments and conformal coatings applied on EEE parts

This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
