DVGW W270 Test and Certification

In DVGW W270 tests, biochemical tests, hygienic tests and other related material tests and product certification procedures are performed as formulation evaluation when the product comes into direct contact with drinking water.

Since the follow-up procedure is usually determined by the results of each step-by-step technical evaluation and testing, the advice of an experienced technical expert is an important factor in achieving successful certification for your company.
