ASTM G179-2004適用范圍

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本規(guī)范提供了制造和使用金屬黑白面板溫度裝置的具體信息，以測(cè)量自然風(fēng)化試驗(yàn)期間涂層金屬試樣的最高（黑色）和最低最高（白色）溫度。

1.1.1黑色或白色面板的結(jié)構(gòu)對(duì)指示溫度有顯著影響。本標(biāo)準(zhǔn)描述了所研究面板的堅(jiān)固結(jié)構(gòu)，與其他黑色面板結(jié)構(gòu)并排比較時(shí)，已證明其可提供最高、最一致的溫度。

1.2本規(guī)范包括設(shè)計(jì)要求和定量測(cè)量技術(shù)的詳細(xì)信息，這將導(dǎo)致正確選擇材料并用于黑白面板溫度傳感器。

1.3本標(biāo)準(zhǔn)并非旨在解決與其使用相關(guān)的所有安全問題（如有）。本標(biāo)準(zhǔn)的使用者有責(zé)任在使用前建立適當(dāng)?shù)陌踩?、健康和環(huán)境實(shí)踐，并確定監(jiān)管要求的適用性。

注1：

沒有同等的ISO標(biāo)準(zhǔn)描述自然風(fēng)化試驗(yàn)中黑面板傳感器的選擇和使用。

1.4本國際標(biāo)準(zhǔn)是根據(jù)世界貿(mào)易組織技術(shù)性貿(mào)易壁壘（TBT）委員會(huì)發(fā)布的《關(guān)于制定國際標(biāo)準(zhǔn)、指南和建議的原則的決定》中確立的國際公認(rèn)標(biāo)準(zhǔn)化原則制定的。
