This European Standard was approved by CENELEC on 2006-03-01. 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, 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, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 32A/235/FDIS, future edition 6 of IEC 60282-1, prepared by SC 32A, High-voltage
fuses, of IEC TC 32, Fuses, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60282-1 on 2006-03-01.
This European Standard supersedes EN 60282-1:2002.
The main changes introduced by this EN 60282-1:2006 are as follows:
- definition and dedicated test requirements for so-called "organic fuses";
- definition and requirements for maximum application temperature in order to cover applications in
which the fuses are used in surrounding temperatures above 40 °C;
- clarification and improvements for testing fuses that exhibit a cross-over current;
- information about fuses operated in parallel.
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) 2006-12-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-03-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 60282-1:2005 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60694 NOTE  Harmonized as EN 60694:1996 (not modified).
IEC 60890 NOTE  Harmonized as CLC/TR 60890:1987 (not modified).
IEC 62271-100 NOTE  Harmonized as EN 62271-100:2001 + A1:2002 (not modified).
