GSO ASTM E179:2021 Scope
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.
1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
