1.1 本规程提供了使用密封剂的信息，通过在建筑施工中常见的接缝、空隙和贯穿件（通常称为“侧翼路径”）上适当应用密封剂来降低内墙、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类似标准。 1.3 本标准无意解决接缝、空隙和贯穿件的防火或安全要求- 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。 1.4 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、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 建筑施工中的墙壁、天花板和地板，特别是那些轻质结构的墙壁、天花板和地板，以及那些设计用于减少或限制声音传播的墙壁、天花板和地板，如果不小心密封通常出现的接缝、空隙和穿透物，则可能具有不良的声音传播特性。未密封的接缝、空隙和贯穿件将显著增加这些类型结构的声音传输特性。通过密封它们，可以通过消除“侧翼路径”大大减少声音的传播。 ”

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 “flanking paths.” 1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations. 1.3 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. 1.4 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. 1.5 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, especially those that are of lightweight construction, and that are designed to reduce or limit sound transmission, can have undesirable sound transmission characteristics if care is not taken to seal joints, voids, and penetrations that typically occur. Unsealed joints, voids, and penetrations will substantially increase the sound transmission characteristics of these types of construction. By sealing them the transmission of sound can be substantially diminished by eliminating “flanking paths.”
