ISO 13628-5:2009规定了石油和天然气行业脐带及相关配套设备的设计，材料选择，制造，设计验证，测试，安装和运行的要求。辅助设备不包括顶部硬件。顶部硬件是指在上侧挂断终端之上没有永久连接到脐带的任何硬件。 ISO 13628-5:2009适用于单独或组合使用的包含电缆，光纤，热塑性软管和金属管等组件的脐带;以及用于静态或动态服务的脐带，具有表面，表面 - 海底和海底海底路线。 ISO 13628-5:2009不适用于相关的组件连接器，除非它们影响脐带或其辅助设备的性能。 ISO 13628-5:2009仅适用于具有以下尺寸的管壁:壁厚，t 6 mm，内径，IDï50,8 mm（2 in）。大于这些尺寸的管状产品可以被认为是管道/管道，并且可以根据公认的管道/管线标准来设计和制造。 ISO 13628-5:2009不适用于等级低于的管或软管

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.
