标准范围
IEC 60794-3-40:2022是一个系列规范，涵盖了通过吹入和/或拉入可进入和不可进入的雨水和卫生下水道进行安装的下水道电缆和导管。使用本文件涵盖的组件构建的系统应符合IEC 60794-3部分规范的要求。下水道电缆和导管结构需要满足下水道运营公司和/或协会关于化学、环境、操作、清洁和一般维护条件的不同要求。附件A和附件B中报告了描述下水道电缆特性和安装方法的优先应用，用于非人可进入的下水道。第5条描述了在雨水和卫生下水道中通过吹、拉或其他方式安装的下水道电缆和导管的特性。可以在此系列规范的基础上编制详细规范。根据这一考虑因素解释验收标准是很重要的。测试的纤维数量代表下水道电缆，并由客户和供应商商定。这第二版取消并取代了2008年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:本文件遵循系列规范的新结构:符号和缩写包含在第3条中，第4条成为4.1光纤、4.2电缆元件和4.3光纤电缆结构的一般要求；附件D已被删除，因为它是IEC TR 62691的一部分；通过交叉引用IEC 60794-1-1、IEC 60793-2、IEC 60794-3和IEC 60794-1-2x系列，本文件得到了简化；更新了拉伸试验的纤维应变余量；特性表5、表6、表7移至附录A（资料性）。
IEC 60794-3-40: 2022 is a family specification that covers sewer cables and conduits for installation by blowing and/or pulling in man accessible and non-man accessible storm and sanitary sewers. Systems built with components covered by this document are subject to the requirements of sectional specification IEC 60794-3. Sewer cable and conduit constructions need to meet the different requirements of the sewer operating companies and/or associations regarding chemical, environmental, operational, cleaning and in general maintenance conditions. Preferential applications, describing sewer cable characteristics versus methods of installation is reported in Annex A and Annex B for non-man accessible sewers. Clause 5 describes characteristics of sewer cables and conduits for installation by blowing, pulling or other means in storm and sanitary sewers. Detail specifications can be prepared on the basis of this family specification. It is important that acceptance criteria are interpreted with respect to this consideration. The number of fibres tested is representative of the sewer cable and is agreed between the customer and the supplier. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- this document follows the new structure for family specifications: symbols and abbreviations were included in Clause 3, and Clause 4 became the General requirements with 4.1 Optical fibres, 4.2 Cable element and 4.3 Optical fibre cable construction;
- Annex D has been removed as it is part of IEC TR 62691;
- this document has been streamlined by cross-referencing IEC 60794-1-1, IEC 60793-2, IEC 60794-3 and the IEC 60794-1-2x series;
- the fibre strain allowance for tensile tests was updated;
- characteristics Table 5, Table 6, Table 7 were moved to the Annex A (informative).
