DIN EN 16602-70-09:2015-05

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 calculations: - Solar absorptance using spectrometer (αs) - (see Annex C.2); - Comparative test method (αp) - (see Annex C.3); - Infrared emittance using thermal test method (εh) - (see Annex C.4); - Infrared emittance using IR spectrometer (εh) - (see annex C.5); - Infrared emittance using portable equipment (εn) - (see 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. This document (EN 16602-70-10:2015) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document has been developed to specifically cover space systems and therefore has precedence over any European Standard since it covers the same scope but with a wider domain of applicability (for example aerospace). The responsible German body is Working Committee NA 131-10-01 AA "Interoperabilität von Informations-, Kommunikations- und Navigationssystemen" ("Interoperability of information, communication and navigation systems") of the Aerospace Standards Committee (NL) at DIN.
