It also gives performance requirements forall components including joints. Joint design and gasket shape are outside the scope of this EuropeanStandard.NOTE 2 In this European Standard, all pressures are relative pressures expressed in bars (100 kPa = 1 bar).【中国标准分类号】: Q82【国际标准分类号】: 23_040_10;23_040_40【页数】: 76P.;A4【正文语种】: 英语
