ISO 14531-1:2002规定了气体燃料供应用交联聚乙烯（PE-X）管道的物理性能和机械性能要求。此外，它还规定了尺寸要求，并规定了一些一般材料特性（包括耐化学性），以及以管道形式生产的PE-X的分类方案。 当与ISO 14531的其他部分一起使用时，ISO 14531-1:2002可作为设计、制造和安装PE-X管道系统（PE-X管道、PE-X熔合配件和机械配件）的基础，以供应D类和E类碳氢燃料。

ISO 14531-1:2002 specifies the physical properties and mechanical-performance requirements for crosslinked polyethylene (PE-X) pipes intended for use in the supply of gaseous fuels. In addition, it lays down dimensional requirements and specifies some general material properties (including chemical resistance) together with a classification scheme for PE-X produced in the form of pipe. ISO 14531-1:2002, when used in conjunction with the other parts of ISO 14531, is applicable as the basis for the design, manufacture and installation of PE-X piping systems (PE-X pipes, PE-X fusion fittings and mechanical fittings) for the supply of category D and category E hydrocarbon-based fuels.
