1.1 本规范涵盖导管内电缆（CIC），它是一种光滑壁、可卷绕的高密度聚乙烯（HDPE）导管（导管），包含预组装的电线和电缆。导管的外径是受控的，其中包裹的电线或电缆可以由单个或多个配置组成，这些配置包括电线/电力线或电缆、光纤、传统铜通信、同轴电缆或其任何组合。CIC配置在挤出过程中预组装到导管中，并用于商业、工业、运输、政府和公用事业应用的行业特定设计中 1.2 本规范并不试图确定每种可能的预装配导管/电缆配置，而是旨在确定材料和最小组装产品特性，以优化可靠性和使用寿命。 1.3 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。 注1: UL 1990和CSA C22.2 No.327的范围与D3485类似；然而，在范围和要求上存在差异。 注2: 最终用户可以选择将单个或多个电线或电缆配置现场安装到现场安装的导管中。如果聚乙烯导管将现场安装电线或电缆配置，则应选择更合适的规范，以确定导管的材料、尺寸、工艺和性能测试 F2160 、UL 651A、CSA C22.2 No.327或NEMA TC-7。 注3: 每当以不同单位显示两组值时，英制单位为标准单位，而括号中的单位（公制单位）仅供参考。 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。

1.1 This specification covers cable in conduit (CIC), which is a smooth-walled, coilable, high-density polyethylene (HDPE) conduit (duct) that contains preassembled wires and cables. The outside diameter of the conduit is controlled and the wire or cable encased within may be comprised of single or multiple configurations consisting of electrical/power wires or cables, fiber optic, traditional copper communication, coaxial cable, or any combination thereof. CIC configurations are preassembled into the conduit during the extrusion process and in industry-specific designs for use in commercial, industrial, transportation, government, and utility applications 1.2 This specification does not attempt to identify every possible preassembled conduit/cable configuration but is intended to identify material and minimum assembled product properties for optimizing reliability and service life. 1.3 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. Note 1: UL 1990 and CSA C22.2 No.327 have a similar scope to D3485; however, there are differences in scope and requirements. Note 2: End users may elect to field install single or multiple wire or cable configurations into field-installed conduit. In the case where polyethylene conduit is to have the wire or cable configurations field installed, then the more appropriate specifications to select for establishing the conduit’s material, dimensional, workmanship, and property tests would be Specification F2160 , UL 651A, CSA C22.2 No.327 or NEMA TC-7. Note 3: Whenever two sets of values are presented, in different units, the imperial units are the standard, while those in the parentheses (metric units) are provided for informational purposes. 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.
