DVGW W 270
Plastic and rubber based gasket materials to be applied in contact with drinking water should comply to the requirements for microbiological growth according to the DVGW standard W270.
DVGW standard W 270 describes a method for the assessment of enhancement of microbial growth on non-metallic materials in contact with drinking water. The test is carried out on gasket sheets of the material. European standard EN 16421 Method 2 refers to this method.
Who is this for?
A valid Test Certificate proving the compliance of gasket sheet with DVGW W270 is necessary for manufacturers, traders and suppliers of plastic or rubber materials, parts and products, equipment and machinery.
