输送气体燃料用埋设的、高耐冲击的聚氯乙烯(PVC-HI)管道.第3部分:最大操作压力为1巴(100 kPa)的管件和鞍座

[中文适用范围]： ISO 6993 的这一部分给出了由高抗冲聚氯乙烯 (PVC-HI) 制成的全端耐负载配件和鞍座的要求，用于通过具有工作温度的埋地管道供应气体燃料温度范围为 0 °C 至 +30 °C（含），最大工作压力为 1 bar (100 kPa)1)。 它仅适用于由高抗冲 PVC 材料 PVC-A、PVC-CPE 和 PVC-EPR 制造的配件和鞍座。 它适用于带有弹性密封元件和溶剂胶类型的接头。 配件和鞍座适用于那些不含有浓度足以损害配件/鞍座材料性能的潜在破坏性成分的气体。 [外文原描述]： ISO 6993-3:2006 gives the requirements for full-end load-resistant fittings and saddles 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 fittings and saddles manufactured from the high-impact PVC materials PVC-A, PVC-CPE and PVC-EPR. It is applicable to joints with elastomeric sealing elements and of the solvent cement type. The fittings and saddles are suitable for those gases not containing potentially damaging components in such concentrations as to impair the properties of the fitting/saddle material.
