1.1 本规范规定了从高于环境温度到1000°F（538°C）的高温环境下，柔性可拆卸和可重复使用的保温毯的材料和制造的最低要求。 1.2 本规范分别涉及工业应用、室外商业应用和室内商业应用。工业应用和室外商业应用的毯子绝缘必须具有耐候性和耐液体化学品性。室内商业应用的毯子保温层最高使用温度限制在500°F（260°C），不需要耐候或耐化学品，通常用于HVAC、管道和其他分配蒸汽或水的轻型室内管道系统，或两者兼用。 1.3 以英寸-磅单位表示的数值应视为标准值。括号中给出的数值是国际单位制的数学转换，仅供参考，不被视为标准。 1.4 本标准并不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，并确定监管限制的适用性。 1.5 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》中确立的国际公认标准化原则制定的。

1.1 This specification addresses the minimum requirements for materials and fabrication of flexible removable and reusable blanket insulation for hot service, from above ambient temperatures to 1000°F (538°C). 1.2 This specification separately addresses industrial applications, outdoor commercial applications, and indoor commercial applications. Blanket insulation for industrial applications and outdoor commercial applications must be weather resistant and resistant to liquid chemicals. Blanket insulation for indoor commercial applications is limited to 500°F (260°C) maximum use temperature, is not required to be either weather resistant or resistant to chemicals, and is typically used for HVAC, plumbing, and other light grade indoor piping systems that distribute steam or water, or both. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. 1.5 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.
