Description

ASTM E430-11

Historical Standard: Standard Test Methods for Measurement of Gloss of High-Gloss Surfaces by Abridged Goniophotometry

ASTM E430

Scope

1.1 These test methods cover the measurement of the reflection characteristics responsible for the glossy appearance of high-gloss surfaces. Three test methods, A, B and C, are provided for evaluating such surface characteristics at specular angles of 30°, 20° and 30°, 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.

1.3 The DOI of a glossy surface is generally independent of its curvature. The DOI measurement by this test method is limited to flat or flattenable surfaces.
