At present, the WSD has a General Acceptance (GA) system in place to pre-approve plumbing products used in new plumbing projects. BS EN ISO/IEC 17067 sets out the key elements of a product certification scheme, which are good pointers for enhancement of the material approval system. Amongst others, surveillance is an element to maintain the validity of the statement of conformity.
To further enhance the conformity of plumbing products with the GA requirements, the WSD implements a surveillance programme for GA products. For details, please refer to WSD Circular Letter No. 8/2017 in the link below:-
