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 48B/1584/FDIS, future edition 2 of IEC 60352-2, prepared by SC 48B, Connectors,
of IEC TC 48, Electromechanical components and mechanical structures for electronic equipment, was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60352-2 on
2006-03-01.
This European Standard supersedes EN 60352-2:1994 + A1:1997 + A2:2002.
It includes the following major technical changes with respect to EN 60352-2:1994 and its amendments:
a) the contents of clauses have been re-arranged, for example the old Clauses 5, 6, 7, 8 and 9 are now
included in the new Clause 4, Requirements;
b) Subclause 4.3.1, the material requirements for crimp barrels have been changed from Vickers
hardness into more appropriate tensile strength requirements and the requirements have been
opened to other materials, if it is of suitable characteristics;
c) Subclause 4.3.3, Surface finishes: the tin-lead has been replaced by tin-alloy to comply with RoHS
legislation. Other plating materials, such as nickel, may be used provided their suitability has been
proven;
d) Subclause 5.1.4, Recovering, has been added;
e) Table 2, example of other materials, has been shortened;
f) Subclause 5.2.4.5 and Figure 7, Current loading, cyclic: the length of wire between two specimens
has been changed to a “minimum of 150 mm” to comply with regional requirements;
g) Subclause 5.2.4.6, Crimping at low temperature, has been changed to “under consideration”;
h) Subclause 15.4 of amendment A1 has been deleted for the sake of design freedom, because the
dimensions are not widely used as stated; only a minority of products, in most cases older ones have
these dimensions.
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 60352-2:2006 was approved by CENELEC as a European
Standard without any modification.
