This European Standard was approved by CENELEC on 2012-08-29. 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 CEN-CENELEC Management Centre 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 CEN-CENELEC Management Centre has the same status as the official versions.

Foreword
The text of document 49/995/FDIS, future edition 2 of IEC 61240, prepared by IEC TC 49 "Piezoelectric,
dielectric and electrostatic devices and associated materials for frequency control, selection and
detection" was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as
EN 61240:2012.

The following dates are fixed:
(dop) 2013-05-29
• latest date by which the document has
to be implemented at national level by
publication of an identical national
standard or by endorsement
(dow) 2015-08-29
• latest date by which the national
standards conflicting with the
document have to be withdrawn

This document supersedes EN 61240:1997.
EN 61240:2012 includes the following significant technical changes with respect to EN 61240:1997:
– outline drawings have been changed from three views (top, front and bottom) to that based on ISO
layout in the third-angle projection, in which the view from the right has been added to the top, front and
bottom views;
– reference line and geometrical dimensions of the package for enclosures have been changed for
practical use;
– information on miniaturized leadless ceramic enclosures of piezoelectric devices (SMD) for frequency
control and selection has been included in an annex.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all
