Regulation 31 testing applies to chemicals and
construction products used by water undertakers,
from the source of the water up to the point of
delivery to the consumerís building. It sets out how
approvals can be given to such construction products
and materials that do not prejudice water quality
and consumer safety.
Typically approval under Regulation 31 will involve the following testing.
The tests needed to show compliance with Regulation 31 are determined, on a
product-to-product basis, by the Drinking Water Inspectorate (DWI) on behalf
of the Secretary of State for the Environment, Food & Rural Affairs.
The DWI will consider the full formulation of a product, together with its method of manufacture or application, and then specifiy what testing, if any, will be needed to meet the requirements of Regulation 31.
Conformance with BS 6920 is essential for products requiring approval under
Regulation 31 and The Water Quality Centre offer a fast and efficient
service to meet your BS 6920 test requirements.
Products which satisfy the requirements of Regulation 31 are published on the DWI website.
