1.1 本规程提供了使用密封剂的信息，通过将密封剂适当应用于建筑施工中常见的接缝、空隙和贯穿件（通常称为空气传播声音侧翼路径），来降低内墙、天花板和地板的声音传输特性。 1.2 对本标准具有管辖权的委员会不知道其他组织发布的任何可比标准。 1.3 以国际单位制表示的数值应视为标准。SI单位后括号中给出的值仅供参考，不被视为标准值。 1.4 本标准并不旨在解决接缝、空隙和贯穿火灾的防火或安全要求- 额定墙壁、天花板和地板组件。防火组件可能需要额外的要求，以满足适用的建筑规范规定。 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。 ====意义和用途====== 4.1 建筑结构中的墙壁、天花板和地板，如果接缝、空隙或贯穿件密封不当，将无法实现所需的声音传输损失。接头、空隙和贯穿件的适当密封将通过减少空气传播的声音侧面路径来增加声音传输损失。

1.1 This practice provides information for the use of sealants to reduce sound transmission characteristics of interior walls, ceilings, and floors by proper application of sealants to joints, voids, and penetrations normally found in building construction, which are commonly referred to as airborne sound flanking paths. 1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 1.4 This standard does not purport to address fire stopping or safing requirements for joints, voids, and penetrations through fire-rated wall, ceiling, and floor assemblies. Additional requirements may be necessary for fire-rated assemblies to meet the applicable building code provisions. 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. ====== Significance And Use ====== 4.1 Walls, ceilings, and floors in building construction with improperly sealed joints, voids, or penetrations will not achieve the desired sound transmission loss. Proper sealing of joints, voids, and penetrations will increase sound transmission loss by reducing airborne sound flanking paths.
