This standard (EN 16602-70-09:2015) originates from ECSS-Q-ST-70-09C. This European Standard s
28、hall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2015, and conflicting national standards shall be withdrawn at the latest by July 2015. Attention is drawn to the possibility that some of the elements of this documen
29、t 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. This document has been developed to
30、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 countries are bound to implement thi
31、s 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, Poland, Portugal, Romania, Slovaki

DIN EN 16602-70-09:2015-05 EN 16602-70-09:2015 (E) 6 Introduction The thermo-optical properties of materials are of importance to enable the calculation of the thermal housekeeping and radiative heat transfer. This Standard desc
33、ribes the methodology, instruments, equipment and samples, used to calculate the thermo-optical properties of thermal-control materials, i.e. solar absorptance s or p and the infrared emittance eh or en. In general this procedure has been written in connection with instruments and equipment availabl
34、e at ONERA, INTESPACE and ESTEC; however, any supplier is encouraged to built up his own instrument or equipment provided the accuracy of the results is equivalent to the one specified herein. In this Standard, the supplier is identified as the entity that performs the test. DIN EN 16602-70-09:2015-
35、05 EN 16602-70-09:2015 (E) 7 1 Scope This Standard describes the methodology, instruments, equipment and samples, used to calculate the thermo-optical properties of thermal-control materials. The following test methods are detailed in this Standard including the configuration of samples and calculat
36、ions: Solar absorptance using spectrometer (s) - (see Annex C.2). Comparative test method (p) - (see Annex C.3). Infrared emittance using thermal test method (eh) - (see Annex C.4). Infrared emittance using IR spectrometer (eh) - (see annex C.5). Infrared emittance using portable equipment (en) - (s
37、ee Annex C.6). This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

42、 intensity of the incident light to the transmitted or reflected light 3.2.2 emittance (e) ratio of the radiant intensity of the specimen to that emitted by a black body radiator at the same temperature and under the same geometric and wavelength conditions NOTE For example: Hemispherical emittance
43、(eh) - conditions for incident or viewing of flux over a hemispherical region. Normal emittance (en) - conditions for incidence or viewing through a solid angle normal to the specimen. 3.2.3 solar absorptance () ratio of the solar radiant flux absorbed by a material (or body) to that incident upon i
44、t NOTE Differentiation is made between two methods: Spectroscopic method using a photospectrometer covering the range from 0,25 mm up to 2,5 mm for the determination of s. Portable equipment using a xenon flash for relative measurements (p). 3.3 Abbreviated terms The abbreviated terms defined in ECS
45、S-S-ST-00-01 apply. DIN EN 16602-70-09:2015-05 EN 16602-70-09:2015 (E) 10 4 Requirements 4.1 Preparatory conditions 4.1.1 Hazards, health and safety precautions a. For “Safety and security” ECSS-Q-ST-20-07C shall apply. NOTE For example, for hazard and health (safety) and for access control (securit
46、y). 4.1.2 Preparation of samples 4.1.2.1 Configuration a. The supplier shall prepare the material samples according to the process specification or manufacturers data. b. The material shall be representative of batch variance. NOTE For example: the application procedure for paint can result in diffe
47、rent thermo-optical properties, depending on the painter and the type of spray gun used. This is the reason why the samples are coated or made at the same time as the workpiece. 4.1.2.2 Cleaning a. Cleaning method and other treatment of the sample shall be the same (and not more) as for the flight h
48、ardware. NOTE In particular, solar absorptance properties are very sensitive to contamination and if the sample or the flight hardware is contaminated (even by hand grease), the test results are completely erroneous. 4.1.2.3 Handling and storage a. The supplier shall handle the samples with clean ny
49、lon or lint-free gloves. DIN EN 16602-70-09:2015-05 EN 16602-70-09:2015 (E) 11 b. The supplier shall store the samples in a cleanliness-controlled area, with a room temperature of (20 3) C and relative humidity of (55 10) %. c. The supplier shall shield coated surfaces from contact by using polyethylene or polypropylene bags or sheets. d. The supplier shall avoid mechanical damage of the sample by packing the polyethylene or polypropylene-wrapped workpieces in cl
