1.1 本规范涵盖膨胀或剥落蛭石松散填充绝缘的组成和物理特性。本规范还包括确定材料可接受性的测试程序。这些测试程序主要处理与建筑物热围护结构相关的温度范围内的材料性能；然而，这种绝缘材料的商用温度范围为-119至850°F（-84至454°C）。有关特殊应用，请参阅制造商的说明。 1. 2. 本规范还涵盖了蛭石的成分和特性，蛭石经过表面处理以产生装置的拒水性。 1.3 当隔热材料、附件和系统的安装或使用可能造成安全或健康问题时，制造商应向用户提供与推荐使用公司产品有关的任何已知问题的适当最新信息，并应建议在安全使用时采取的保护措施。 1.4 以下适用于试验方法 E84 和试验方法 E136 . 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 1.5 以下适用于试验方法 E84 和试验方法 E136 . 防火测试本身就很危险。在进行这些测试时，应采取适当的人员和财产保护措施。 1.6 以英寸-磅为单位的数值应视为标准值。 括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.7 以下安全危险警告仅适用于测试方法部分第节 9 ，本规范: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 有关具体的危险说明，请参阅第节 12 . 1.8 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。

1.1 This specification covers the composition and physical properties of expanded or exfoliated vermiculite loose-fill insulation. The specification also includes the testing procedures by which the acceptability of the material shall be determined. These testing procedures deal primarily with material performance in the temperature range associated with the thermal envelope of buildings; however, the commercially usable temperature range for this insulation is from –119 to 850°F (–84 to 454°C). Refer to manufacturer's instructions for specialized applications. 1.2 The specification also covers the composition and properties of vermiculite that has been surface-treated to produce water repellency for installations. 1.3 When the installation or use of thermal insulation materials, accessories, and systems may pose safety or health problems, the manufacturer shall provide the user with appropriate current information regarding any known problems associated with the recommended use of the company's products, and shall also recommend protective measures to be employed in their safe utilization. 1.4 The following applies to Test Method E84 and Test Method E136 . This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions. 1.5 The following applies to Test Method E84 and Test Method E136 . Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.6 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. 1.7 The following safety hazards caveat pertains only to the test methods portion, Section 9 , of this specification: 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 hazard statements, see Section 12 . 1.8 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.
