….‘no material or substance, either alone or in combination with any other material or substance or with the contents of any water fitting of which it forms a part, which causes or is likely to cause contamination of water shall be used in the construction, installation, renewal, repair or replacement of any water fitting which conveys or receives, or may convey or receive, water supplied for domestic or food production purposes.’ …. 

WRAS Material Approval will only be granted to materials which have satisfied the requirements of BS 6920:2000 Parts 1 and 2, together with Part 3 for hot water usage. “Suitability of non-metallic products for use in contact with water intended for human consumption with regard to their effect on the quality of water.” 

WRAS Material Approvals are valid for a maximum of five years. In order to maintain a WRAS Material Approval, products are retested every 5 years. 

The approval details the material/component covered by the scope of the approval, any specific conditions that limit the scope of its use (curing conditions for example) and the maximum water temperature it can be subjected to.
