Historical Standard: Standard Guide for Selection of Geometric Conditions for Measurement of Reflection and Transmission Properties of Materials (Withdrawn 2012)<\/h4>\n
\n

ASTM E179<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This guide is intended for use in selecting terminology, measurement scales, and instrumentation for describing or evaluating such appearance characteristics as glossiness, opacity, lightness, transparency, and haziness in terms of reflected or transmitted light. This guide does not consider the spectral variations responsible for color, but the geometric variables described herein can importantly affect instrumentally measured values of color. This guide is general in scope rather than specific as to instrument or material.<\/p>\n

Keywords<\/strong><\/p>\n

geometric conditions; reflection; transmission<\/p>\n

ICS Code<\/strong><\/p>\n

ICS Number Code 17.180.20 (Colours and measurement of light)<\/p>\n
