1.1 本规程规定了热涂接缝和裂缝密封剂和填料的熔化或加热程序，或两者兼而有之，为制备密封剂和填料实验室评估中使用的试样做准备。有关取样要求、试样数量、熔化和加热的温度和时间以及测试所需的试样数量，请参阅具体的标准材料规范。 1.2 本规程适用于硅酸盐水泥和沥青中使用的热涂接缝和裂缝密封剂和填料- 混凝土路面。 1.3 以国际单位制或英寸-磅单位表示的值应单独视为标准值。每个系统中所述的值可能不是完全等效的；因此，每个系统都应独立使用。将两个系统的值结合起来可能会导致不符合标准。 1.4 警告-- 美国环保署和许多州机构已将汞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，并对材料具有腐蚀性。处理汞和含汞产品时应小心。详情请参阅适用的产品材料安全数据表（MSDS）和美国环保署的网站--http://www.epa.gov/mercury/faq.htm--获取更多信息。用户应该知道，州法律可能禁止向您的州销售汞和/或含汞产品。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。 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，并确定监管限制的适用性。 有关具体注意事项，请参阅第节 7. . 1.6 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 制造商、用户和测试机构应使用此做法。本规程的使用为热涂密封剂和填料的熔化或加热建立了统一的程序。其目的不是建立与每种接缝密封剂和填料相关的测试程序或测试条件。

1.1 This practice establishes the procedure for melting or heating, or both, of hot-applied joint and crack sealants and fillers in preparation for the making of test specimens used in the laboratory evaluations of the sealants and fillers. Refer to the specific standard material specification for sampling requirements, test sample quantity, temperatures and times for melting and heating, and the number of specimens required for testing. 1.2 This practice is applicable to the hot-applied joint and crack sealants and fillers used in both portland cement and asphaltic-concrete pavements. 1.3 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. 1.4 Warning— Mercury has been designated by the 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 and/or mercury-containing products into your state may be prohibited by state law. 1.5 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. For specific precautions, see Section 7 . 1.6 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 It is intended that this practice be used by manufacturers, users, and testing agencies. The use of this practice establishes a uniform procedure for the melting or heating of hot-applied sealants and fillers. It is not intended to establish test procedures or conditions of test which are associated with each of the joint sealants and fillers.
