National foreword

This Draft for Development has been prepared by Subcommittee B/525/9 and is the
English language version of ENV 1999-1-2:1998 Eurocode 9: Design of aluminium
structures Part 1-2: General rules - structural fire design, as published by the
European Committee for Standardization.

ENV 1999-1-2:1998 results from a programme of work sponsored by the European
Commission to make available a common set of rules for the structural and
geotechnical design of building and civil engineering works.

This publication is not to be regarded as a British Standard.

An ENV is made available for provisional application, but does not have the status
of a European Standard. The aim is to use the experience gained to modify the ENV
so that it can be adopted as a European Standard.

Fire safety in the UK is covered by national regulations in the form of Building
Regulations, and in particular Approved Document B (1992 edition) of those
regulations. There are no current British Standards that give a method of calculating
fire resistance of structural members of Aluminium or its alloys.

The values for certain parameters in the ENV Eurocodes may be set by individual
CEN members so as to meet the requirements of national regulations. These
parameters are designated by × in the ENV.

The BSI technical committee responsible do not propose any changes to the boxed
values for this code.

The ENV allows (clause 2.4.1) structural analysis by several methods. For verifying
standard fire resistance requirements, a member analysis is usually considered
sufficient.

Users of this documents are invited to comment on its technical content, ease of use
and any ambiguities and anomalies. These comments will be taken into account
when preparing the UK national response to CEN on the question of whether the
ENV can be converted to an EN.

Comments should be sent in writing to the secretary of Subcommittee B/525/9, BSI,
389 Chiswick High Road, London W4 4Al, quoting the document reference, the
relevant clause and, where possible, a proposed revision, within 2 years of the issue
of this document.

Summary of pages

This document comprises a front cover, an inside front cover, pages i and ii, the
ENV title page, pages 2 to 56, an inside back cover and a back cover.

The BSI copyright notice displayed in this document indicates when the document
was last issued.
