National foreword

This British Standard reproduces verbatim ISO 4065:1996 and implements it as the UK national standard.

The UK participation in its preparation was entrusted to Technical Committee PRI/61, Plastics piping systems and components, which has the responsibility to:

— aid enquirers to understand the text;
— present to the responsible international/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 committee can be obtained on request to its secretary.

Cross-references

The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or using the “Find” facility of the BSI Standards Electronic Catalogue.

This British Standard partially supersedes BS 5556:1978: in particular, Table 4 of ISO 4065:1996 corresponds to but is not identical with Table 4 of BS 5556:1978. Hence for existing standards which refer specifically to BS 5556, that reference still applies until changed by amendment, revision or agreement to make reference to BS ISO 4065 or ISO 4065. For fresh applications, BS 5556 should be regarded as obsolescent for the purposes covered by BS ISO 4065, which should be referred to accordingly.

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.

This British Standard, having been prepared under the direction of the Sector Board for Materials and Chemicals, was published under the authority of the Standards Board and comes into effect on 15 May 1997
