1.1 本规范涵盖了用作隔热或吸声材料或两者兼用的自支撑喷涂纤维素纤维的物理财产。 1.2 本规范涵盖了用于温度不超过82.2°C且温度通常保持在65.6°C以下的气动应用的化学处理纤维素材料。 1.2.1 类型I- 涂有液体粘合剂的材料，适用于暴露或封闭应用。 1.2.2 类型II- 含有干粘合剂的材料，该干粘合剂在安装过程中被水活化，仅用于封闭或覆盖的应用。 1.3 本规范仅为材料规范，不适用于制造商提供的应用方法。 1.4 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.5 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。 1.6 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 The specification covers the physical properties of self-supported spray applied cellulosic fibers intended for use as thermal insulation or an acoustical absorbent material, or both. 1.2 This specification covers chemically treated cellulosic materials intended for pneumatic applications where temperatures do not exceed 82.2°C and where temperatures will routinely remain below 65.6°C. 1.2.1 Type I— Material applied with liquid adhesive and suitable for either exposed or enclosed applications. 1.2.2 Type II— Materials containing a dry adhesive that is activated by water during installation and intended only for enclosed or covered applications. 1.3 This is a material specification only and is not intended to deal with methods of application that are supplied by the manufacturer. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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.
