标准摘要
[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) 制成的非端部承重配件的要求,用于通过埋地管道供应气体燃料,工作温度范围为0 °C 至 +30 °C(含),最大工作压力为 200 mbar (20 kPa)1)。 它仅适用于由高强度 PVC 材料 PVC-A、PVC-CPE 和 PVC-EPR 制造的且具有带弹性体密封元件的接头的配件。 该配件适用于那些不含有浓度足以损害配件材料性能的潜在破坏成分的气体。 [外文原描述]: ISO 6993-2:2005 gives the requirements for non-end load-bearing fittings 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 200 mbar (20 kPa).
