ASTM G179-2004适用范围

1.1 This specification provides specific information for the manufacturing and use of metal black and white panel temperature devices to measure temperatures that estimate highest maximum (black) and lowest maximum (white) temperatures of coated metal specimens during natural weathering tests.

1.1.1 The construction of a black or white panel has a significant effect on the indicated temperature. This standard describes a robust construction from the panels investigated, which has been shown to provide the highest, most consistent temperatures when compared side-by-side with other black panel constructions.

1.2 This specification includes details on design requirements and quantitative measurement techniques, which will lead to the proper selection of materials and use for black and white panel temperature sensors.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and 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 for natural weathering tests.

1.4 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.

1.1本规范提供了制造和使用金属黑白面板温度装置的具体信息，以测量自然风化试验期间涂层金属试样的最高（黑色）和最低最高（白色）温度。

1.1.1黑色或白色面板的结构对指示温度有显著影响。本标准描述了所研究面板的坚固结构，与其他黑色面板结构并排比较时，已证明其可提供最高、最一致的温度。

1.2本规范包括设计要求和定量测量技术的详细信息，这将导致正确选择材料并用于黑白面板温度传感器。

1.3本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管要求的适用性。

注1：

没有同等的ISO标准描述自然风化试验中黑面板传感器的选择和使用。

1.4本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
