WRAS Approval for the UK Market

NSF offers Water Regulations Advisory Scheme (WRAS) approval which allows manufacturers to demonstrate their products’ compliance with the Water Supply (Water Fittings) Regulations or Scottish Byelaws for the UK market. Approval requires that a water fitting does not incur waste, misuse, undue consumption or contamination in the water supply and that it is of an appropriate quality and standard.

NSF International and WRAS have unique responsibilities in the WRAS approvals process.
