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 (black) and minimum maximum (white) 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.

1.3 This standard is not intended to address all safety concerns, if any, associated with its use. It is the responsibility of users of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory requirements prior to use.

Note 1: There is no equivalent ISO standard describing the selection and use of black panel sensors in natural burn-in testing.

1.4 This international standard is based on internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the WTO Committee on Technical Barriers to Trade.
