1.1 本规程涵盖了在新的或现有的住房和其他框架建筑的天花板、阁楼、地板和墙壁空腔中安装纤维素和矿物纤维松散填充绝缘材料的程序。 1.2 本规程仅适用于通过气动或浇注应用安装由纤维素材料或矿物纤维组成的干燥松散填充隔热材料。 1.3 本规程涵盖了从安装前检查到安装后程序的安装过程。它不包括绝缘材料的生产。 1.4 本规程无意取代制造商的安装说明，但应与此类说明一起使用。本惯例无意取代地方、州或联邦法规。 1.5 本规程假设安装人员对安装隔热材料所需的适用规范和法规、安全规程、工具、设备和方法具有良好的工作知识。 它还假设安装人员了解影响隔热安装的住宅建筑的基本原理。 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 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。 有关具体的预防说明，请参阅第节 5. . ====意义和用途====== 4.1 本规程认识到，绝缘的有效性、安全性和耐久性不仅取决于绝缘材料的质量，还取决于其正确安装。 4.2 保温层安装不当会降低其热效率，引发火灾风险和其他不安全条件，并促进其安装结构的劣化。安装不当可能导致的特定危险包括以下原因引起的火灾:( 1. )嵌入式照明灯具中的热量积聚；( 2. )电气布线部件的劣化或故障；( 3. )过电流保护装置与接线不匹配导致的热量积聚；或( 4. )木材结构的劣化和因水分积聚而导致的油漆失效。 4.3 本规程提供了有助于确保安全有效地安装绝缘层的一般程序。必须注意的是，现有建筑物的实际情况差异很大，在某些情况下，必须采取大量额外的注意和预防措施，以确保有效和安全的安装。

1.1 This practice covers procedures for the installation of cellulosic and mineral fiber loose-fill insulation in ceilings, attics, and floor and wall cavities of new or existing housing and other framed buildings. 1.2 This practice applies only to the installation of dry loose-fill thermal insulation consisting of cellulosic materials or mineral fiber by pneumatic or pouring application. 1.3 This practice covers the installation process from pre-installation inspection through post-installation procedure. It does not cover the production of the insulation materials. 1.4 This practice is not intended to replace the manufacturer's installation instructions, but shall be used in conjunction with such instructions. This practice is not intended to supersede local, state, or federal codes. 1.5 This practice assumes that the installer possesses a good working knowledge of the applicable codes and regulations, safety practices, tools, equipment, and methods necessary for the installation of thermal insulation materials. It also assumes that the installer understands the fundamentals of residential construction that affect the installation of insulation. 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 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. For specific precautionary statements, see Section 5 . ====== Significance And Use ====== 4.1 This practice recognizes that effectiveness, safety, and durability of insulation depend not only on the quality of the insulating materials, but also on their proper installation. 4.2 Improper installation of insulation can reduce its thermal effectiveness, cause fire risks and other unsafe conditions, and promote deterioration for the structure in which it is installed. Specific hazards that can result from improper installation include fires caused by ( 1 ) heat build-up in recessed lighting fixtures; ( 2 ) deterioration or failure of electrical wiring components; ( 3 ) heat build-up resulting from overcurrent protection devices incorrectly matched to wiring; or ( 4 ) deterioration in wood structures and paint failure due to moisture accumulation. 4.3 This practice provides general procedures that will help ensure the installation of insulation in a safe and effective manner. It must be noted that actual conditions in existing buildings vary greatly, and in some cases substantial additional care and precaution must be taken to ensure effective and safe installation.
