ISO 13628-5:20 09规定了石油和天然气行业脐带缆及相关辅助设备的设计、材料选择、制造、设计验证、测试、安装和操作的要求并给出了建议。辅助设备不包括顶部硬件。上部硬件是指在上部悬挂终端上方未永久连接到脐带缆的任何硬件。 ISO 13628-5:20 09适用于包含组件的脐带缆，例如单独或组合的电缆、光纤、热塑性软管和金属管；以及用于静态或动态服务的脐带缆，具有表面-表面、表面-海底和海底-海底路线。 ISO 13628-5:20 09不适用于相关组件连接器，除非它们影响脐带缆或其辅助设备的性能。ISO 13628-5:20 09仅适用于具有以下尺寸的管材:壁厚，t？6毫米，内径，内径？50.8毫米（2英寸）。大于这些尺寸的管状产品可被视为管道/管线管，并且期望它们根据公认的管道/管线管标准进行设计和制造。 ISO 13628-5:20 09不适用于额定低于7 MPa（1 015 psi）的管道或软管，也不适用于高于标准额定电压=3.6/6（7,2）kV rms的电缆额定电压，其中U0、U和Um如IEC 60502-1和IEC 60502-2中所定义。

ISO 13628-5:2009 specifies requirements and gives recommendations for the design, material selection, manufacture, design verification, testing, installation and operation of umbilicals and associated ancillary equipment for the petroleum and natural gas industries. Ancillary equipment does not include top side hardware. Topside hardware refers to any hardware that is not permanently attached to the umbilical, above the topside hang-off termination. ISO 13628-5:2009 applies to umbilicals containing components, such as electrical cables, optical fibres, thermoplastic hoses and metallic tubes, either alone or in combination; and to umbilicals for static or dynamic service, with surface-surface, surface-subsea and subsea-subsea routings. ISO 13628-5:2009 does not apply to the associated component connectors, unless they affect the performance of the umbilical or that of its ancillary equipment. ISO 13628-5:2009 applies only to tubes with the following dimensions: wall thickness, t？6 mm, internal diameter, ID？50,8 mm (2 in). Tubular products greater than these dimensions can be regarded as pipe/linepipe and it is expected that they be designed and manufactured according to a recognised pipeline/linepipe standard. ISO 13628-5:2009 does not apply to a tube or hose rated lower than 7 MPa (1 015 psi), or to electric cable voltage ratings above standard rated voltages _{= 3,6/6(7,2) kV rms, where U0, U and Um are as defined in IEC 60502-1 and IEC 60502-2.}
