标准范围

检查带有一根管道和两个连接端部配件的组件密封性的方法和试验组件规范，根据其自由长度进行弯曲。该弯曲具有根据管道标称直径和压力计算的平均半径。在等于标称压力三倍的内部压力下，试样至少应在1小时内无泄漏。给出了一个合适的测试装置的示意图。

Specification of a method and a test assembly for checking the leakproofness of an assembly with one pipe and two connected end fittings, to which bending is applied according to its free length. This bending has an average radius calculated from the pipe nominal diameter and pressure. The test specimen shall be free from leaks for at least 1 h under internal pressure equal to three times the nominal pressure. A diagram of a suitable test apparatur is given.
