Le présent document spécifie une méthode pour déterminer la solidité des teintures et les propriétés de vieillissement de tous les types et formes de textiles teints ou imprimés et/ou autres supports organiques sous l'action d'une source de lumière artificielle représentative de la lumière naturelle du jour et sous l'action simultanée de la chaleur.
<p>This document specifies a method for determining the colour fastness and ageing properties of all kinds and forms of dyed and printed textiles and/or other organic substrates under the action of an artificial light source representative of natural daylight (D65), and under the simultaneous action of heat. Of the five different sets of exposure conditions specified (see 7.1.1), four use D65, and the other one uses a somewhat lower cut-off wavelength. The test method gives special consideration to the light and heat conditions that occur in the interior of a motor vehicle.</p> <p>The five different sets of conditions using the different optical filter systems specified can produce different test results. Results from tests performed using different apparatus (instrument types) for the same set of conditions and optical filter system are not comparable because comparable performance has not been validated</p>
