1.1 本规范涵盖了采用空气热传输的太阳能系统中使用的橡胶密封件的一般要求。例如管道和阻尼器密封。特定应用可能需要其他要求，这些要求在规定时优先于这些要求。 注1: 收集器的橡胶密封件见规范 第3667页 和 第3771页 . 1.2 设计要求仅适用于使用中密封件热膨胀或收缩过程中橡胶的容许挠度以及模制和挤压密封件的尺寸公差。 1.3 本规范不包括与密封件制造或安装相关的要求。 1.4 以国际单位表示的值应视为标准值。本标准不包括其他计量单位。 1.5 以下安全隐患警告仅适用于测试方法部分，第节 10 本规范的: 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建立适当的安全、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》中确立的国际公认标准化原则制定的。

1.1 This specification covers the general requirements for the rubber seals used in solar energy systems employing air-heat transport. Examples are duct and damper seals. Particular applications may necessitate other requirements that would take precedence over these requirements when specified. Note 1: Rubber seals for the collector are covered in Specifications D3667 and D3771 . 1.2 Design requirement pertains only to permissible deflections of the rubber during thermal expansion or contraction of the seal in use and the tolerances in dimensions of molded and extruded seals. 1.3 This specification does not include requirements pertaining to the fabrication or installation of the seals. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 The following safety hazards caveat pertains only to the test methods portion, Section 10 , of this specification: 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.
