ISO 6993-1:2006规定了由高抗冲聚氯乙烯（PVC-HI）制成的管道的要求，这些管道拟用于通过工作温度范围为0摄氏度至+30摄氏度（含+30摄氏度）且最大工作压力为1巴（100千帕）的埋地管道供应气体燃料。 仅适用于由高抗冲PVC材料PVC-A、PVC-CPE和PVC-EPR制成的管道。管道适用于不含潜在有害成分的气体，其浓度会损害管道材料的性能。

ISO 6993-1:2006 specifies the requirements for pipes made of high-impact poly(vinyl chloride) (PVC-HI) intended to be used for the supply of gaseous fuels through buried pipelines having an operating temperature range of 0 degrees Celsius up to and including +30 degrees Celsius and a maximum operating pressure of 1 bar (100 kPa). It is applicable only to pipes manufactured from the high-impact PVC materials PVC-A, PVC-CPE and PVC-EPR. The pipes are suitable for those gases not containing potentially damaging components in such concentrations as to impair the properties of the pipe material.
