This standard (EN 16602-70-58:2015) originates from ECSS-Q-S

22、T-70-58C. 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of an identical text or by endorsement, at the latest by March 2016, and conflicting national standards shall be withdrawn at the latest by March 2016. Attention is drawn to the possibility that

23、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 Free Trade Association.

24、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 following

25、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, Norway

BS EN 16602-70-58:2015EN 16602-70-58:2015 (E) 6 Introduction The UN Outer Space Treaty of 1967 sets up the general principles applicable to the exploration and use of outer space. Article IX o

27、f the Outer Space Treaty constitutes the primary statement of international law: “States parties shall pursue studies of outer space, including the Moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment

28、of the Earth resulting from the introduction of extraterrestrial matter and, when necessary, adopt appropriate measures for this purpose”. Harmful contamination in that sense is defined as biological contamination, including organic-constituents, to protect the environment in order to allow future e

29、xobiology research. The Committee On Space Research (COSPAR) has established some planetary protection guidelines, based on the Outer Space Treaty. These guidelines impose requirements on spaceflight missions according to target body/mission type combinations. The objective of this Standard is to en

30、sure that the proper procedures to control the microbiological contamination in controlled environments are in place to meet the planetary protection constraints. BS EN 16602-70-58:2015EN 16602-70-58:2015 (E) 7 1 Scope This standard establishes the principles and basic methodology for microbiologica

31、l control of cleanrooms and associated controlled environments with planetary protection constraints. This standard does not address: the microbiological contamination control of spaceflight hardware; molecular contamination control. Reference is made to other documents; fire and safety regulations;

32、 for these, see regulatory requirements and other national or local documentation. This standard does not lay down the methods for determining the microbiological and particulate cleanliness levels. Reference is made to other documents. This standard may be tailored for the specific characteristic a

33、nd constrains of a space project in conformance with ECSS-S-ST-00.

For dated references, sub

34、sequent amendments to, or revision of any of these publications do not apply, However, parties to agreements based on this ECSS Standard are encouraged to investigate the possibility of applying the more recent editions of the normative documents indicated below.
