1.1 本规程涵盖了沥青涂层加速和室外风化试验板的制备程序。它被认为适合于制备0.25至2.54 mm[0.010至0.100范围内的膜厚度 英寸]。 1.2 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值结合起来可能会导致不符合标准。 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制定适当的安全、健康和环境实践，并确定监管限制的适用性。 ( 警告- 汞已被美国环保局和许多国家机构指定为可导致中枢神经系统、肾脏和肝脏损伤的危险物质。汞或其蒸气可能对健康有害，对材料具有腐蚀性。处理汞和含汞产品时应注意。有关详细信息，请参阅适用的产品材料安全数据表（MSDS）和美国环保局的网站，http://www.epa.gov/mercury/faq.htm，以获取更多信息。 用户应意识到，在您所在的州销售汞或含汞产品，或两者兼有，可能会受到州法律的禁止。） 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 这种制备试板的做法大大增加了在后续测试中获得可重复结果的可能性。

1.1 This practice covers a procedure for the preparation of accelerated and outdoor weathering test panels of bituminous coatings. It is considered suitable for the preparation of film thicknesses in the range from 0.25 to 2.54 mm [0.010 to 0.100 in.]. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 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 limitations prior to use. ( Warning— Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA's website, http://www.epa.gov/mercury/faq.htm, for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law.) 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. ====== Significance And Use ====== 4.1 This practice for preparation of test panels greatly increases the likelihood of achieving reproducible results in subsequent testing.
