1.1 本规范涵盖了适用于开放或封闭天花板空间的喷涂纤维素纤维稳定隔热材料的成分和物理性能，无论坡度如何，温度范围为-49至194°F（-45至90°C）。 1.2 稳定纤维素纤维隔热材料是通过在松散填充纤维素纤维隔热层中添加粘合剂而制成的。粘合剂要么在制造时添加到隔热层中，必要时在安装时通过加水激活，要么在安装时以其他方式添加到隔热材料中。 1.3 本材料规范不涉及制造商提供的应用方法。 1.4 以英寸-磅单位表示的值应被视为标准值。括号中给出的国际单位制仅供参考。 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。 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。

1.1 This specification covers the composition and physical properties of spray-applied cellulosic fiber stabilized thermal insulation applied to open or closed ceiling spaces, regardless of slope, where temperatures range from –49 to 194°F (–45 to 90°C). 1.2 Stabilized cellulosic fiber thermal insulation is produced by the addition of adhesive(s) to loose-fill cellulosic fiber insulation. The adhesive(s) are either added to the insulation at time of manufacture and, if necessary, activated by the addition of water when installed or the adhesive(s) are otherwise added to the insulation at the time of installation. 1.3 This is a material specification that is not intended to deal with methods of application that are supplied by the manufacturer. 1.4 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only. 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. 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.
