WRAS Approval Services

NSF offers third-party testing of fittings to meet the requirements of the Water Supply (Water Fittings) Regulations 1999, the Water Supply (Water Fittings) (Scotland) Byelaws 2014 and the Water Supply (Water Fittings) Regulations (Northern Ireland) 2009.

After our testing is complete, we send the test reports to the WRAS agency, which will provide the approval. This approval requires that a water fitting does not cause waste, misuse, undue consumption or contamination to the water supply and that it is of an appropriate quality and standard. Non-metallic materials that contact water are also required to comply with BS 6920.

To make a formal application for testing, please fill out the contact form below. Once we receive this form, we assess the application and advise you of the test requirements, samples required, any additional information required and the costs. We then test your samples and, subject to satisfactory test results, forward the test report to WRAS for approval.
