适用范围：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.
