ECSS-Q-70-03A 7 April 2006 Terms, definitions and abbreviated terms 3.1 Terms and definitions For the purposes of this document the terms and definitions given in ECSS-P-001 and the following apply. 3.1.1 anodizing placing a protective film coating on a metal surface by an electrolytic or chemical action 3.1.2 batch (material) material that originates from the same casting lot, and followed the same transformation processes and the same heat treatment 3.1.3 emittance (ε) 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 Exampe 1 Hemispherical emittance (εh) - conditions for incidence or viewing of flux over a hemispherical region. Exampe 2 Normal emittance (εn) - conditions for incidence or viewing through a solid angle normal to the specimen. Ratio refers to the emissivity normal to the surface of the emitting body 3.1.4 solar absorbance (αs) ratio of the solar radiant flux absorbed by a material (or body) to that incident upon it NOTE Differentiation is made between two methods: 1. Spectroscopic method using a photospectrometer covering the range from 0,25 µm to 2,5 µm for the determination of αs. 2. Portable equipment using a xenon flash for relative measurements (αp). 3 13
