This standard (EN 16602-70-13:2015) ori

16、ginates from ECSS-Q-ST-70-13C Rev.1. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2015, and conflicting national standards shall be withdrawn at the latest by July 2015. Attention is drawn

17、 to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European

18、 Free Trade Association. This document supersedes EN 14099:2001. This document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Re

19、gulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland,

BS EN 16602-70-13:2015EN 16602-70-13:2015 (E) 5 1 Scope This Standard details a test in which pressure-sensitive tapes are used

21、 to assess the suitability of, for example, coatings, paints, films and other thin materials, proposed for use on spacecraft and associated equipment. Surface coatings, such as thermal control paints and corrosion protection coatings, are affected, both on the ground and after launch, by exposure to

22、 the environment. It is therefore important that the adhesion of the coating to the relevant substrate remains at an acceptable level after exposure to the relevant environmental condition. The following materials and assemblies are covered by this test method: organic coating, e.g. varnishes, paint

23、s and plastic films; metallic finishes on, for example, printed circuit boards, second-surface mirrors, thermal radiators, plastic films; adhesive layers; composite thin films; small assemblies, e.g. solar cells having attached glass covers. This standard may be tailored for the specific characteris

24、tics and constrains of a space project in conformance with ECSS-S-ST-00.
