FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. In exceptional

circumstances, a technical committee may propose the publication of a technical specification
when
– the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
– the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
IEC 61994-4-1, which is a technical specification, has been prepared by IEC technical
committee 49: Piezoelectric and dielectric devices for frequency control and selection.
This second edition of IEC 61994-4-1 cancels and replaces the first edition published in 2001.
This edition constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
– this second edition takes into account new terms and definitions given in IEC 60758, third
edition, published in 2004.

Full information on the voting for the approval of this technical specification can be found in the

report on voting indicated in the above table.

This publication has been drafted in accordance with the IS0/lEC Directives, Part 2.

IEC 61994 consists of the following parts under the general title, Piezoelectric and dielectric

devices for frequency control and selection – Glossary:

－ Part 1: Piezoelectric and dielectric resonators
－ Part 2: Piezoelectric and dielectric filters

－ Part 3: Piezoelectric oscillators
－ Part 4-1: Piezoelectric materials– Synthetic quartz crystal
－ Part 4-2: Piezoelectric and dielectric materials – Piezoelectric ceramics

－ Part 4-3: Materials for dielectric devices
－ Part 4-4: Materials – Materials for Surface Acoustic Wave (SAW) devices
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• transformed into an international standard;
• reconfirmed;
