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. |
