A new ECSS standard for environmental durability testing of optical coatings for space application
Many different environmental factors can have an effect on optical coating durability for space applications. This includes in-orbit effects such as vacuum exposure, UV radiation, particle radiation, atomic oxygen, thermal cycling, contamination and orbital debris, as well as ground based effects such as cleaning, contamination and humidity (See Reference). There are a large range of national and international standards available which define test requirements and methods for coating durability, mostly for ground applications. Space projects currently utilize combinations of these existing standards, and adapt them according to specific requirements for the project. However there can be discrepancies between projects about the specific standards used, leading to conflicting definitions about when a coating is “space qualified”. The supplier and customer often needs to re-negotiate very general aspects of coating qualification for each new project, leading to increased time and effort.
