(Main)Anodizing of aluminium and its alloys - Measurement of specular reflectance and specular gloss of anodic oxidation coatings at angles of 20°, 45°, 60° or 85° (ISO 7668:2021)
Anodizing of aluminium and its alloys - Measurement of specular reflectance and specular gloss of anodic oxidation coatings at angles of 20°, 45°, 60° or 85° (ISO 7668:2021)
This document specifies methods for the measurement of specular reflectance and specular gloss of flat samples of anodized aluminium using geometries of 20° (Method A), 45° (Method B), 60° (Method C) and 85° (Method D) and of specular reflectance by an additional 45° method (Method E) employing a narrow acceptance angle.
The methods described are intended mainly for use with clear anodized surfaces. They can be used with colour-anodized aluminium, but only with similar colours.
Anodisieren von Aluminium und Aluminiumlegierungen - Messung des gerichteten Reflexionsgrades und des Spiegelglanzes von anodisch erzeugten Oxidschichten bei Winkeln von 20°, 45°, 60° oder 85° (ISO 7668:2021)
Dieses Dokument legt Verfahren zur Messung des gerichteten Reflexionsgrades und des Spiegelglanzes von ebenen Proben aus anodisch oxidiertem Aluminium unter Anwendung der geometrischen Messbedingungen bei 20° (Verfahren A), 45° (Verfahren B), 60° (Verfahren C) und 85° (Verfahren D) sowie ein weiteres Verfahren zur Messung des gerichteten Reflexionsgrades bei 45° (Verfahren E) fest, bei dem ein kleiner Empfängerwinkel verwendet wird.
Die beschriebenen Verfahren sind hauptsächlich für farblos anodisierte Oberflächen vorgesehen. Sie können für farbig anodisiertes Aluminium verwendet werden, aber nur bei gleichen Farben.
Anodisation de l'aluminium et de ses alliages - Mesurage des caractéristiques de réflectivité et de brillant spéculaires des couches anodiques à angle fixe de 20°, 45°, 60° ou 85° (ISO 7668:2021)
Le présent document spécifie des méthodes de mesure de la réflectivité spéculaire et du brillant spéculaire d'échantillons plats d'aluminium anodisé sous des angles de 20° (Méthode A), 45° (Méthode B), 60° (Méthode C) et 85° (Méthode D), plus une autre méthode à 45° (Méthode E) à petit angle d'ouverture pour le mesurage de la réflectivité spéculaire.
Les méthodes décrites sont principalement utilisables sur des surfaces plates anodisées claires. Elles peuvent être utilisées sur de l'aluminium anodisé coloré, mais dans ce cas, uniquement pour des couleurs semblables.
