EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of DVGW W270 testing. According to DVGW worksheet W270, products and materials are tested for migration of chemicals and growth of microorganisms.
Materials used in the drinking water sector must have a surface that excludes unwanted surface contamination by microorganisms. This is very important from a hygienic-microbiological point of view. In addition to various technical and mechanical requirements, hygienic conditions must also be guaranteed.
Plastic and rubber-based gasket materials to be applied in contact with drinking water must comply with the microbiological growth requirements according to DVGW standard W270.
DVGW standard W270 describes a method for evaluating the enhancement of microbial growth on non-metallic materials in contact with drinking water. The test is carried out on the gasket sheets of the material.
Manufacturers, traders and suppliers of plastic or rubber materials, parts and products, equipment and machinery require a valid Test Certificate proving the seal layer's compatibility with DVGW W270. According to the W270 worksheet, the test is a pure compound test, so it must be done with the material used for its manufacture.
The W270 test consists of placing the rubber material inside an existing water pipe for a period of 3 months. The result is a volumetric assessment of bacteriological growth scraped from the walls of the plates. In this case, too, the requirements vary according to the categories related to the contact surface of the article (A, B, C, D2 and DXNUMX), as in the KTW standard. Such a certificate is valid for a period of five years.
