Materials used in contact with drinking water,
whether within buildings or in the water supply
system require testing and approval to show that
they will not adversely affect water quality.
BS 6920 specifies the requirements for the
suitability of non metallic materials for use in
contact with cold or hot water, with regard to their
effect on water quality. Such products include water
fittings, rubber and plastic components, materials
used in coating and protection, and materials for
jointing, lubrication and sealing.
The Water Quality Centre offers a comprehensive
service for testing materials to BS 6920 to meet
WRAS and DWI Regulation 31 requirements.
A materials testing service for
manufacturers and suppliers of non-metallic
materials used in contact with drinking
water within buildings. Essential for UK
manufacturers as well as international
companies wishing to sell in the UK.
