ASTM E430-19<\/h3>\n

Historical Standard: Standard Test Methods for Measurement of Gloss of High-Gloss Surfaces by Abridged Goniophotometry<\/h4>\n
\n

ASTM E430<\/h4>\n

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

\n

1.1<\/span> 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 20\u00b0 and 30\u00b0, respectively. These test methods are not suitable for diffuse finish surfaces nor do they measure color, another appearance attribute.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> As originally developed by Tingle and others (see Refs 1<\/span><\/span> and 2<\/span><\/span>),2<\/span><\/span> the test methods were applied only to bright metals. Recently they have been applied to high-gloss automotive finishes and other nonmetallic surfaces.<\/p>\n<\/p><\/div>\n

\n

1.3<\/span> 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.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> 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.<\/i><\/p>\n<\/p><\/div>\n
