JIS Z 2333:2005 (R2014)

This Japanese Industrial Standard specifies the method of test for leaks in which the ammonia gas leaking from the test object such as tank (single wall, double wall, fuel tank), vessel (pressure vessel, vacuum vessel), ammonia storage (a large capacity refrigerating system, fertilizer store house), parts (laminating specification, backing specification, double wall specification), sealed part by different material (glass, metal) and others (complicated piping system, flexible container) is detected by developer. Moreover, this test is available to detect the leak rate up to approximately 1 multiplied by 8-minex Pa *cubic metres/s.
