Information about this document

This Published Document has been developed to build on the guidance previously given in BS 8558 on the flushing and disinfection of services supplying water for domestic use within buildings and their curtilages, which was regarded as beyond the scope of that British Standard. The intention is to eventually develop this as a British Standard.

A review of this Published Document will be carried out not later than five years after its publication. Informative annexes about the pH impact of various chlorine doses are planned for inclusion in a future revision of this Published Document or when it is converted to a British Standard. Testing is currently being undertaken by Scottish Water.

Any observations or comments will be welcomed. These should be sent to the Secretary of BSI Technical Committee EH/3 at BSI Head Office, at the address on the back cover. On the basis of the replies received, the responsible BSI Committee will judge whether the Published Document can be converted to a British Standard.

Test laboratory accreditation. Users of this British Standard are advised to consider the desirability of selecting test laboratories that are accredited to BS EN ISO/IEC 17025 by a national or international accreditation body.
