ASTM E430-97(2003)
Historical Standard: ASTM E430-97(2003) Standard Test Methods for Measurement of Gloss of High-Gloss Surfaces by Goniophotometry
SUPERSEDED (see Active link, below)
ASTM E430
1. Scope
1.1 These test methods cover the measurement of the reflection characteristics responsible for the glossy appearance of high-gloss surfaces. Two test methods, A and B, are provided for evaluating such surface characteristics at specular angles of 30 and 20, respectively. These test methods are not suitable for diffuse finish surfaces nor do they measure color, another appearance attribute.
1.2 As originally developed by Tingle and others (see Refs 1 and 2 ), the test methods were applied only to bright metals. Recently they have been applied to high-gloss automotive finishes and other nonmetallic surfaces.
