BRITISH STANDARD BS EN12056-3:2000

The European Standard EN 12056-3:2000 has the status of a British Standard. NO COPYING WITHOUT BSI PERMISSION EXCEPT AS PERMITTED BY COPYRIGHT LAW BS EN12056-3:2000.

National foreword

This British Standard is the official English language version of EN 120563:2000. It supersedes BS 6367:1983 which is withdrawn.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

A list of organizations represented on this subcommittee can be obtained on request to its secretary. The national annexes are an informative element of this standard and contain information provided to support easier implementation of EN 12056-3:2000 in the United Kingdom, within the framework envisaged by the scope of that standard. They, therefore, constitute a revision of those parts of BS 6367:1983 that are not otherwise superseded by BS EN 12056-3:2000. However, users are reminded that only the normative elements of the adopted European Standard set out the provisions to which it is necessary to conform to form part of a trade description when citing this British Standard by number or when compliance with it is claimed.
