BS EN 16602-70-17:2020 pdf free.Space product assurance一Durability testing of coatings and surface finishes.
BS EN 16602-70-17 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.The following normative documents contain provisions which, through reference in this text, constitute provisions of this ECSS Standard. For dated references, subsequent amendments to, or revision of any of these publications do not apply. However, parties to agreements based on this ECSS Standard are encouraged to investigate the possibility of applying the more recent editions of the normative documents indicated below. For undated references, the latest edition of the publication referred to applies.This standard gives a minimum set of tests to validate the coating process and also to give some meaningful results about exposure of the coating in its operating environment. However, full qualification of the coating for a specific space mission depends on the mission parameters, and it can be also necessary to define additional tests which are beyond the scope of the standard.The practical severity of any test listed can be limited by the substrate (for example, it is not possible to perform the humidity test on hygroscopic substrates).BS EN 16602-70-17 pdf download.
