Well equipped and modern laboratory

Kiwa has a well equipped and modern test laboratory. For decades our laboratory has tested drinking water products, in view of product certification, according to evaluation guidelines, quality requirements and (inter)national standards. We are able to test a wide scope of products used in (drinking) water installations. But of course the Kiwa test laboratory is also able to test products in other markets.

The Dutch Council of Accreditation (RvA) has accredited our laboratory according to ISO 17025.
