Testing and certification

Inspection companies such as DNV, Lloyd’s Register EMEA, Bureau Veritas, Det Norske Veritas, BwB quality testing service, RINA, ABS and TÜV approve fittings at our company just about every day.

Our QM system is also audited at regular intervals to get the best out of all the products for you. Both water and air tests are carried out on our test stands in order to ensure that valves and fittings perfectly perform their function as desired. We carry out water tests with up to 1,200 bar and air tests with up to 50 bar, with both processes always dependent on the nominal diameters. On our test stands, we can put pipes and fittings with nominal diameters between DN 6 and DN 700 through their paces.Our extensive range covers all relevant sizes. We test fittings with large nominal diameters on our own test stand manufactured in-house.
