This standard (EN 16602-70-29:2014) originates from ECSS-Q-ST-70-29C. This European Standard shall

29、 be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2015, and conflicting national standards shall be withdrawn at the latest by April 2015. Attention is drawn to the possibility that some of the elements of this document

30、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 supersedes EN 14100:2001. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association

31、. 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 Regulations, the national standards organizations of the followin

32、g 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, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norw

DIN EN 16602-70-29:2015-06 EN 16602-70-29:2014 (E) 5 1 Scope All non-metallic materials release trace contaminants into the surrounding environment; the extent to which this occurs is depend

34、ent on the nature of the material concerned. In the closed environment of a manned spacecraft contaminants within the atmosphere are potentially dangerous with respect to toxicity and its consequences for the safety of the crew. This Standard defines a test procedure for the determination of the tra

35、ce contaminants release by non-metallic materials under a set of closely controlled conditions. The test procedure covers both individual materials and assembled articles. In this Standard the supplier means the testing authority that is responsible for specifying and executing the offgassing tests.

36、 This Standard describes a test to provide data for aid in the evaluation of the suitability of assembled articles and materials for use in a space vehicle crew compartment. The data obtained are in respect of the nature and quantity of organic and inorganic volatile contaminants evolved when subjec

37、ted to the crew compartment environment. This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00.
