标准范围

ISO 22621-5:2010规定了聚酰胺（PA）管道系统的适用性要求，该管道系统拟在最大工作压力（MOP）不超过20巴（2兆帕）的情况下埋设并用于供应气体燃料。它规定了电熔合和对接熔合接头的定义。它还规定了试件接头的制备方法，以及在这些接头上进行的试验，以评估系统在正常和极端条件下的适用性。此外，它还规定了所指测试方法的测试参数。与ISO 22621的其他部分一起，它适用于PA配件及其接头，以及带有PA部件的接头。

ISO 22621-5:2010 specifies the requirements of fitness for purpose of the polyamide (PA) piping system, intended to be buried and used for the supply of gaseous fuels at maximum operating pressures (MOP) up to and including 20 bar (2 MPa).It specifies the definitions of electrofusion and butt fusion joints.It also specifies the method of preparation of test piece joints and the tests to be carried out on these joints for assessing the fitness for purpose of the system under normal and extreme conditions.In addition, it specifies the test parameters for the test methods to which it refers.In conjunction with the other parts of ISO 22621, it is applicable to PA fittings, their joints and to joints with components of PA.
