19、:2016ISO 17851:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a

20、subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission

21、 (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should

22、be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identi

23、fying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenien

26、rials are subjected to various factors that may cause damage and deterioration of their service properties. In addition, there are several objective reasons to require improvements in the forecasting of spacecraft material durability in relation to outer space environment impact. The most important

27、reasons are the following: increase of spacecraft lifetime; development of new spacecraft designs (non-hermetic spacecraft, microsatellites, etc.); application of new materials, including nanomaterials; complexity and sensitivity improvement of spacecraft on-board equipment; development of new orbit

28、s in the near-Earth space; implementation of new space projects (manned flight to Mars, building of manned bases on the Moon, etc.).Material durability forecast in relation to space environment impact is based on results of ground tests and mathematical modelling of processes of space environment ef

29、fects on materials and on-board experiments. For high-precision forecasts, it is necessary to choose correctly the set of space environment components which affect a spacecraft in various space regions, and to define their characteristics authentically, to select the principle and minor physical and

30、 chemical processes causing the material degradation under the space environment impact, including possible synergistic effects, to define the requirements to conditions of the ground-based material tests and to applied physical and mathematical models, to define the criteria for structural and func

31、tional material durability to the space environment impact, and to select the correct methods of material durability forecasting for different spacecraft lifetimes in various space regions.This International Standard considers the items above as a unified system. It does not detail specific question

32、s but only determines general principles and criteria for space environment simulation during material tests. Thus, this International Standard does not replace existing International Standards on specific types of space material tests. The basic purpose of this International Standard is to describe

33、 the general test methodologies using the most correct and full initial data on the space environment. Development of a general methodology will determine the role of each existing International Standard on space materials tests more precisely, help understand how existing International Standards pr

34、ovide the general system of space materials tests, and determine tests types for which development of new International Standards is necessary.vi ISO 2016 All rights reservedBS ISO 17851:2016Space systems Space environment simulation for material tests General principles and criteria1 ScopeThis Inte

35、rnational Standard provides a general description of the whole set of space environment components which affect spacecrafts in various outer space regions, and the physical and chemical processes causing material degradation in a space environment, including synergistic effects. This International S

36、tandard defines the most important general principles and criteria of space environment simulation during material tests, and formulates the general requirements to laboratory test facilities and to physical and mathematical models that are applied to the research of the space environment impact on

37、materials. The basic purpose of this International Standard is to provide a general description of the methodology in selecting a set of space environment components and their characteristics during spacecraft material tests, and determine general principles and criteria for the tests.Additionally,

38、such methodology will help in the understanding of the degree of coverage of space materials tests with existing International Standards on the specific test types, and help define the actual directions in developing new International Standards.This International Standard can be applied as a referen
