untitled BRITISH STANDARD BS EN 1155 1997 Incorporating Amendment No 1 and Corrigendum Nos 1, 2 and 3 Building hardware — Electrically powered hold open devices for swing doors — Requirements and test[.]

The European Standard EN 1155:1997, with the incorporation of

amendment A1:2002, has the status of a British Standard

ICS 91.190

This British Standard, having

been prepared under the

direction of the Sector Board for

Building and Civil

Engineering, was published

under the authority of the

Standards Board and comes

EN 1155:1997 (as amended) is a candidate “harmonized” European Standard and fully takes into

account the requirements of the European Commission mandate M/101, Doors, windows, shutters,

gates and related hardware, given under the EU Construction Products Directive (89/106/EEC),

and intended to lead to CE marking The date of applicability of EN 1155:1997 (as amended) as a

“harmonized” European Standard, i.e the date after which this standard may be used for CE

marking purposes, is subject to an announcement in the Official Journal of the European

CE marking At the end of this co-existence period, the national standard(s) will be withdrawn Since BS EN 1155:1997 is the current national standard the changes introduced by amendment

no 1 may be implemented from nine months after publication.

Based on this nominal transition period of twenty-one months, BS EN 1155:1997 (as amended) would be fully effective in September 2004.

NOTE This date is approximate Users of this standard should contact BSI Customer Services for confirmation of withdrawal.

The UK participation in its preparation was entrusted by Technical Committee B/538, Doors,

windows, shutters, hardware and curtain walling, to Subcommittee B/538/4, Building hardware,

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.

1 Scope

This European Standard specifies requirements for separate hold-open devices and also for hold-open mechanisms incorporated in a door closer !intended to be used on fire/smoke compartmentation doors" Electrically powered hold-open devices for swing doors manufactured according to this European Standard can hold a swing door at a fixed position or can allow the door to swing freely In each case interruption of the electrical supply will cause the controlled door to close positively

Electrically powered hold-open devices manufactured in accordance with this European Standard are recommended for use wherever there is a requirement for reliable hold-open and release of self-closing fire/smoke door assemblies

Whilst these devices can incorporate smoke or fire detection elements, the performance of those particular elements is outside the scope of this European Standard

!Door closing devices are covered by EN 1154."
