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@ mainly for satellite applications. This standard applies to 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 applications of coatings for launchers (e.g. high temperature coatings) ? 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
