What is a WRAS Material Approval?


A WRAS approval is an easy way to demonstrate that a material is of a suitable quality and standard and has been tested to demonstrate compliance with BS6920
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.  These require that a water fitting should not cause waste, misuse, undue consumption or contamination of the water supply and must be ‘of an appropriate quality and standard’.


WRAS Material Approval: 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 complies with BS6920.


Where do the regulations apply?
