1.1 本规范涵盖了桥梁用预成型硅树脂接缝密封件的材料要求。密封件由一个预成型为连续长度的硅橡胶压盖组成。其设计应防止在正常移动过程中密封或粘合点产生任何张力。密封件是通过使用硅树脂粘合剂将其粘合到接头集管上进行安装的，其设计目的是密封接头，防止液体侵入。 1.2 括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.3 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。 1.4 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 This specification covers the material requirements for preformed silicone joint seals for bridges. The seal consists of a silicone rubber gland preformed to a continuous length. Its design shall prevent any tension from occurring in the seal or bonding point during normal movement. The seal is installed by bonding it to the joint header with a silicone-based adhesive and is designed to seal the joint, preventing liquid intrusion. 1.2 The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 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. 1.4 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.
