1.1 本规范涵盖膨胀珍珠岩松散填充隔热材料的成分和物理性能。本规范包括确定材料可接受性的测试程序。这些测试程序主要涉及与建筑物热围护结构相关的温度范围内的材料性能；然而，这种隔热材料的商用温度范围是 − 459至1400°F（1至1033 K）。有关特殊应用，请参阅制造商的说明。 1.2 本规范涵盖了经过表面处理的珍珠岩的成分和性能，用于灰尘是一个因素的装置。 1.3 以英寸表示的值- 磅单位应视为标准单位。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.4 以下内容适用于试验方法 E84 和 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，但其本身并未包含在实际火灾条件下对材料、产品和组件进行火灾危险或火灾风险评估所需的所有因素。 1.5 以下内容适用于试验方法 E84 和 E136 -- 火灾测试具有内在的危险性。在进行这些试验时，应为人员和财产提供足够的保护。 1.6 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公司产品的推荐使用相关的任何已知问题的适当当前信息，并应建议在安全使用过程中采取的保护措施。用户应在使用前建立适当的安全和健康实践，并确定监管要求的适用性。 有关其他预防说明，请参阅第节 12 。 1.7 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。 1.8 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。

1.1 This specification covers the composition and physical properties of expanded perlite loose fill insulation. The specification includes the testing procedures by which the acceptability of the material is 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 − 459 to 1400°F (1 to 1033 K). For specialized applications, refer to the manufacturer's instructions. 1.2 The specification covers the composition and properties of perlite that has been surface-treated to produce dust suppression for installations where dust is a factor. 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 The following applies to Test Methods E84 and 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 Methods E84 and E136 — Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.6 When the installation or use of thermal insulation materials, accessories and systems, may pose safety or health problems, the manufacturer shall provide the user 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. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. For additional precautionary statements, see Section 12 . 1.7 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. 1.8 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.
