The WRAS (Water Regulations Advisory Scheme) play an important role in protecting public health, safeguarding water supplies and promoting the efficient use of water within customers’ premises across the UK. The scope of material certification testing includes plumbing faucets, valve parts, rubber products, plastics, etc. All materials that come into contact with water Materials that may be used to manufacture the equipment must comply with BS6920.
ACS (Attestation De Conformite Sanitaire ) is the material safety approval required for materials and products in contact with drinking water in France. All products that come in contact with drinking water must pass ACS certification before they can be legally sold in France.
KTW (Kunststoffe und Trinkwasser), a German quality standard for rubber and plastic components in contact with drinking water.
NSF (The National Sanitation Foundation ) was established in 1944 as an independent, non-profit, non-governmental organization. NSF is an authoritative organization in the field of public health and safety, which is dedicated to standard setting, product testing and certificationS that help protect food, water and the environment.
