21、by July 2015, and conflicting national standards shall be withdrawn at the latest by July 2015.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 document may be the subject of patent rights.

22、t rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association.

25、duction The thermo-optical properties of materials are of importance to enable the calculation of the thermal housekeeping and radiative heat transfer. This Standard describes the methodology, instruments, equipment and samples, used to calculate the thermo-optical properties of thermal-control mate
26、rials, 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 available at ONERA, INTESPACE and ESTEC; however, any supplier is encouraged to built up his own instrument or equipment provided the accu
27、racy of the results is equivalent to the one specified herein. In this Standard, the supplier is identified as the entity that performs the test. BS EN 16602-70-09:2015EN 16602-70-09:2015 (E) 7 1 Scope This Standard describes the methodology, instruments, equipment and samples, used to calculate the
28、 thermo-optical properties of thermal-control materials. The following test methods are detailed in this Standard including the configuration of samples and calculations: Solar absorptance using spectrometer (s) - (see Annex C.2). Comparative test method (p) - (see Annex C.3). Infrared emittance usi
29、ng thermal test method (eh) - (see Annex C.4). Infrared emittance using IR spectrometer (eh) - (see annex C.5). Infrared emittance using portable equipment (en) - (see Annex C.6).

34、e purpose of this Standard, the terms and definitions from ECSS-S-ST-00-01 apply. 3.2 Terms specific to the present standard 3.2.1 absorptance ratio of the 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
35、 emitted by a black body radiator at the same temperature and under the same geometric and wavelength conditions NOTE For example: Hemispherical emittance (eh) - conditions for incident or viewing of flux over a hemispherical region. Normal emittance (en) - conditions for incidence or viewing throug
36、h 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 it NOTE Differentiation is made between two methods: Spectroscopic method using a photospectrometer covering the range from 0,25 mm up to 2,5 mm f
37、or the determination of s. Portable equipment using a xenon flash for relative measurements (p). 3.3 Abbreviated terms The abbreviated terms defined in ECSS-S-ST-00-01 apply.

42、th 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 work
43、pieces in clean, dust- and lint-free material. e. The supplier shall label limited-life materials with their relative shelf lives and dates of manufacture. 4.1.2.4 Identification a. The supplier shall use a completed “Material identification card” in conformance with DRD in ECSS-Q-ST-70-02 for sampl
44、es submitted for testing. b. The supplier shall verify the existence of a safety data sheet for hazardous samples NOTE The safety data sheet is a set of information provided by the supplier of the chemical substance. 4.1.3 Facilities 4.1.3.1 Cleanliness a. The supplier shall keep the work area clean
45、 and free of dust. b. The supplier shall use filters for the air used for ventilation. NOTE This is to prevent contamination of the sample. 4.1.3.2 Environmental conditions a. The ambient conditions for the process and work areas shall be (22 3) C with a relative humidity of (55 10) % unless otherwi
46、se stated. 4.1.3.3 Equipment a. The supplier shall define the equipment in the test procedure. 4.2 Selection of test methods a.
