1.1 本规范涵盖喷涂矿物纤维隔热和吸声隔热材料的组成和物理性能。 1.2 这些矿物纤维应通过气动输送至喷嘴，在喷嘴中与水混合。这些矿物纤维应具有与纤维预混合或与水一起添加在喷嘴处的粘合剂。 1.3 喷涂矿物纤维隔热层旨在在环境条件下用于建筑施工。 1.4 本规范仅为材料规范，不包括制造商提供的应用方法。 1.5 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。 1.6 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和健康实践，并确定监管限制的适用性。

1.1 This specification covers the composition and the physical properties of spray-applied mineral fiber thermal and sound absorbing insulation. 1.2 These mineral fibers shall be pneumatically conveyed to a spray nozzle where they are mixed with water. These mineral fibers shall have a binder either pre-mixed with the fibers or added at the spray nozzle with the water. 1.3 The spray-applied mineral fiber insulation is intended for use in building constructions at ambient conditions. 1.4 This is a material specification only and is not intended to cover methods of application that are supplied by the manufacturer. 1.5 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. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
