Water Regulations 英国水标

英国水务法规咨询计划(WRAS)认证,该认证可以让制造商证明其产品符合英国市场的供水(水配件)法规或苏格兰章程。认证要求水配件和材料不会产生废水、误用、过度消耗水资源或造成供水污染(具体BS 6920检测项目包括气味、水质、微生物增长、细菌毒性、重金属等项目),并且符合适当的质量要求和标准。Any water fitting, which when installed, will carry or receive water from the public mains water supply in the UK, must comply with the Water Supply (Water Fittings) Regulations or Scottish Byelaws.  
WRAS Product Approval产品认证: Whole products such as valves, boilers & showers undergo mechanical and water quality testing. This type of approval demonstrates compliance with requirements of the regulations and byelaws, provided the fitting is installed according to any conditions given with the approval. 产品例如:
水冷器、制冰机 等
WRAS Material Approval材料认证: Non-metallic materials & components, such as rubber sheet material & ‘O’ rings, undergo testing only for their effects on water quality.  This type of approval demonstrates that the non-metallic material/component does not itself contaminate the water and therefore satisfies this particular requirement of regulations and byelaws.材料比如:
WRAS product approval involves two levels of testing. We can cover the testing requirements of the non-metallic components in compliance with BS 6920. If found to be compliant with BS 6920 the product would then need to undergo mechanical tests on the complete fitting to gain the second level of approval, which we can advise on.

Regulation 31 Approval
Regarding the Drinking Water Inspectorate (DWI) we can support to carry out analysis in applications for approval under Regulation 31 of the water supply regulations of 2000, including BS EN 12873 leaching tests for non-metallic materials and GCMS analysis.
