The newly laid pipe without fittings and without gas appliances<\/strong> (shut-off valves may also be tested if they can withstand the test pressure and are open during the test, PN 1) is subjected to a test pressure of 1 bar.

Temperature compensation is not required, but is useful. The resolution of the test device is at least 0.1 bar. The test pressure is 1 bar (1000 hPa). During the test, it is recommended to tap the pipe and lightly tap the joints. Leaks must not be visible.<\/strong><\/p>\n<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>
