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.
