Space product assurance - Particle and UV radiation testing for space materials
Materials used in space applications need to be evaluated for their behaviour under Particle and UV Radiation. As part of this evaluation often an exposure to a simulated space environment is performed that can raise questions regarding its accuracy and representativeness. The role of this Standard is to establish a baseline for the testing specification. NOTE The environments covered are electromagnetic radiation and charged particles. This Standard defines the procedures for electromagnetic radiation and charged particles testing of spacecraft materials. These materials include for instance thermal control materials, windows, coatings, and structural materials. The procedures include simulation of the environment and the properties to be verified. This Standard excludes electronic components. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Zagotavljanje varnih proizvodov v vesoljski tehniki - Preskušanje delcev in UV sevanja za vesoljske materiale
Oceniti je treba obnašanje materialov, ki se uporabljajo v vesolju, v okviru sevanja delcev in UV-sevanja. Kot del te ocene se pogosto izvede izpostavljenost simuliranemu vesoljskemu okolju, ki poraja vprašanja v zvezi z njegovo točnostjo in reprezentativnostjo. Vloga tega standarda je določiti osnovno vrednost za preskusno specifikacijo. OPOMBA: Obravnavana okolja so elektromagnetno sevanje in nabiti delci. Ta standard določa postopke za preskušanje elektromagnetnega sevanja in nabitih delcev materialov za vesoljska plovila. Ti materiali na primer zajemajo materiale za nadzor toplote, okna, premaze in strukturne materiale. Med postopke spadajo simulacija okolja in lastnosti, ki jih je treba preveriti. Ta standard ne zajema elektronskih komponent. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

The absorbed dose D is expressed in Gy (1 Gy = 1 j/kg = 100 rad). 3.2.2 acceleration factor
ratio of the intensity of a degrading factor applied to a material at the laboratory during a space simulation versus the intensity of the same degrading factor in space NOTE
It applies to any degrading factor. 3.2.3 bremsstrahlung high-energy electromagnetic radiation in the X-ray energy range emitted by charged particles slowing down by scattering off atomic nuclei NOTE 1 The primary particle is ultimately absorbed while the bremsstrahlung can be highly penetrating. In space, the most common source of bremsstrahlung is electron scattering. NOTE 2 Its energy is continuously distributed down from the energy of the incident particle. 3.2.4 contaminant unwanted molecular or particulate matter (including microbiological matter) on the surface or in the environment of interest, that can affect or degrade the relevant performance or life time SIST EN 16602-70-06:2015
For example: UV, charged particles. 3.2.6 dose profile distribution of the absorbed dose through the depth of the material 3.2.7 ex-situ measurement measurement performed outside the testing facility NOTE 1 Generally it means that these measurements are performed in air at ambient temperature.
NOTE 2 If specific conditions are applied ex-situ, they are described in a corresponding procedure. 3.2.8 fluence time-integration of the flux 3.2.9 flux amount of radiation crossing a surface per unit of time NOTE
It is often expressed in “integral form” as particles per unit area per unit time (e.g. electrons cm-2 s-1) above a certain threshold energy. 3.2.10 in-situ measurement measurement performed inside a chamber (in vacuum or pressurized) 3.2.11 induced space environment environmental factors that result from interactions of the space system with the natural space environment 3.2.12 irradiance quotient of the radiant flux incident on an element of the surface containing the point, by the area of that element NOTE
See also ISO 15856:2003 3.2.13 ionizing radiation form of radiation that has sufficient energy to remove electrons from atoms to produce ions NOTE
It can consist of high energy particles (electrons, protons or alpha particles) or short wavelength electromagnetic radiation (ultraviolet, X-rays and gamma rays). 3.2.14 mean free path average distance that a subatomic particle, ion, atom, or molecule travels between successive collisions with ions, atoms, or molecules SIST EN 16602-70-06:2015
This includes radiation, vacuum, residual atmosphere, and meteoroids. 3.2.16 near ultraviolet (NUV) radiation solar electromagnetic radiation with the wavelength in the range from 200 nm up to 400 nm 3.2.17 reciprocity law statement that the observed property change depends only on the fluence and is independent of the flux 3.2.18 synchrotron radiation continuous electromagnetic radiation created by the acceleration of relativistic charged particles NOTE
For example: this radiation can be generated in a synchrotron or storage ring. 3.2.19 synergism joint action of two or more stimuli whose combination induce a different effect (qualitative and quantitative) than the result of adding the effects of each stimulus taken separately 3.2.20 vacuum ultraviolet (VUV) radiation solar electromagnetic radiations in the wavelength range from 10 nm up to 200 nm NOTE
Also called “Far UV”. 3.3 Abbreviated terms and symbols For the purpose of this Standard, the abbreviated terms from ECSS-S-ST-00-01 and the following apply: Abbreviation Meaning ESH equivalent Sun hour FUV far ultraviolet QCM quartz crystal monitor NUV near ultraviolet UV ultraviolet VUV vacuum ultraviolet
