20、ns need to be evaluated for their behaviour under Particle and UV Radiation. As part of this evaluation often an exposure to a simulated space environment is performed that can raise questions regarding its accuracy and representativeness. The role of this Standard is to establish a baseline for the

21、 testing specification. NOTE The environments covered are electromagnetic radiation and charged particles. This Standard defines the procedures for electromagnetic radiation and charged particles testing of spacecraft materials. These materials include for instance thermal control materials, windows

22、, coatings, and structural materials. The procedures include simulation of the environment and the properties to be verified. This Standard excludes electronic components. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00
