1.1 This specification provides specific information for the manufacture and use of metal black and white panel temperature devices to measure temperatures to estimate the maximum (黑色的) and minimum maximum (白色的) temperatures of coated metal specimens during natural aging tests.

1.1.1 The structure of a black or white panel has a significant effect on the indicated temperature. This standard describes the robust construction of the panels studied, which has been shown to provide the highest, most consistent temperatures compared to other black panel structures.

1.2 The specification includes detailed information on design requirements and quantitative measurement techniques that will lead to the correct selection of materials and temperature sensors for black and white panels.
