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 Ang pamantayang ito ay hindi nilayon upang matugunan ang lahat ng mga alalahanin sa kaligtasan, kung meron man, na nauugnay sa paggamit nito. Responsibilidad ng mga gumagamit ng pamantayang ito na magtatag ng angkop na kaligtasan, health and environmental practices and to determine the applicability of regulatory requirements prior to use.

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

1.4 Ang internasyonal na pamantayang ito ay batay sa mga prinsipyo ng standardisasyon na kinikilala ng internasyonal na itinatag sa Desisyon sa mga Prinsipyo para sa Pag unlad ng mga Internasyonal na Pamantayan, Mga Patnubay at Rekomendasyon na inilabas ng WTO Committee on Technical Barriers to Trade.
