National foreword

This British Standard is the official English language version of EN 12056‑2:2000. It supersedes BS 5572:1994 which is withdrawn.

The UK participation in its preparation was entrusted by Technical Committee B/505, Wastewater engineering, to Subcommittee B/505/21, Roof drainage and sanitary pipework, which has the responsibility to:

— aid enquirers to understand the text;
— present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed;
— monitor related international and European developments and promulgate them in the UK.

The national annexes are an informative element of this British Standard and contain information provided for easier implementation of EN 12056‑2:2000 in the United Kingdom, within the framework envisaged by the scope of the European Standard. Users are reminded that only the normative elements of the adopted European Standard set out the provisions to which it is necessary to conform in order to form part of a trade description when citing this British Standard by number or when compliance with it is claimed.

A list of organizations represented on this subcommittee can be obtained on request to its secretary.
