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. : aeros

32、pace Treaty of 1967 sets up the general principles applicable to the exploration and use of outer space. Article IX of 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, an

33、d conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment 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 defin

34、ed as biological contamination, including organic-constituents, to protect the environment in order to allow future exobiology research. The Committee On Space Research (COSPAR) has established some planetary protection guidelines, based on the Outer Space Treaty. These guidelines impose requirement

35、s on spaceflight missions according to target body/mission type combinations. The objective of this Standard is to ensure that proper procedures for reducing the microbiological contamination on flight hardware are in place to meet the planetary protection constraints. DIN EN 16602-70-56:2015-12 EN

36、16602-70-56:2015 (E) 5 1 Scope This standard specifies procedures for the reduction of microbiological contamination of flight hardware using hydrogen peroxide vapour. The procedures specified in this standard cover: Reduction of microbiological contamination on exposed surfaces. Reduction of microb

37、iological contamination in controlled ambient and vacuum environments. This standard also specifies requirements for the conditioning of the flight hardware, bioburden reduction cycle development, and equipment to be used for applying a bioburden reduction procedure. This standard may be tailored fo

38、r the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00C.
