This European Standard was approved by CENELEC on 2002-07-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
The text of document 94/156/FDIS, future edition 1 of IEC 62246-1, prepared by IEC TC 94,
All-or-nothing electrical relays, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 62246-1 on 2002-07-01.
This European Standard supersedes EN 119000:1996.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2003-04-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2005-07-01
Annexes designated "normative" are part of the body of the standard.
In this standard, annexes A, B and ZA are normative.
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 62246-1:2002 was approved by CENELEC as a European
Standard without any modification.
