This European Standard was approved by CENELEC on 2011-03-17. 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, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Foreword
The text of document 94/314/FDIS, future edition 2 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 2011-03-17.
This European Standard supersedes EN 62246-1:2002 and EN 62246-2:2008.
This edition includes the following significant technical changes with respect to EN 62246-1:2002 and
EN 62246-2:2008:
– update of references, terms and definitions;
– renumbering of clauses to bring them into a more logical order;
– inclusion of the generic specifications for all types of reed switches, but mercury wetted reed switches
have been removed from the scope due to their potential for environmental impact;
– inclusion of three fundamental conformity assessment procedures for quality assessment;
– improvement of electrical endurance tests covering resistive, inductive, capacitive and filament lamp
contact loads;
– renumbering of all annexes in the order they are referenced in the body of the standard;
– improvement of test procedures;
– inclusion of a new Annex C (informative) for electrical endurance test circuit, an Annex D (informative)
for inrush current loads, an Annex E (informative) for conditional short-circuit current test circuit, an
Annex F (informative) for electrical ratings based on classification, an Annex G (informative) for
example of test arrangement for contact reliability test, an Annex H (informative) for example of test
arrangement for making current capacity test and an Annex I (informative) for example of test
arrangement for breaking current capacity test.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
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) 2011-12-17
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-03-17
Annex ZA has been added by CENELEC.
