ASTM E1918-21<\/h3>\n

Active Standard: Standard Test Method for Measuring Solar Reflectance of Horizontal and Low-Sloped Surfaces in the Field<\/h4>\n
\n

ASTM E1918<\/h4>\n

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

\n

1.1<\/span> This test method covers the measurement of solar reflectance of various horizontal and low-sloped surfaces and materials in the field, using an albedometer or pyranometer. The test method is intended for use when the sun angle to the normal from a surface is less than 45\u00b0.<\/p>\n<\/p><\/div>\n

\n

1.2<\/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

Keywords<\/strong><\/p>\n

pyranometer; solar energy; solar reflectance;<\/p>\n

ICS Code<\/strong><\/p>\n

ICS Number Code 17.180.20 (Colours and measurement of light)<\/p>\n
