The high-pressure test, calibration and cable detection are at present the only test methods for testing of installed pipes. The equipment technology supports the user perfect in performance of the high-pressure test according the new recommendation (e.g. ZTV-TKNETZ 40 released 10/2019) 10/2019).
The low-pressure test is together with the calibration and cable detection a test method for installed often thin-walled protective ducts. The equip-ment technology supports the user perfect in performance of the low-pressure test acc. the recommendation EN 1610:2015, as well as the work-sheet DWA-A-139:2009.
