How to access
This link will lead you to the Online Standards Development (OSD) platform for national mirror
committee’s comments. It replaces the project content, which is usually circulated as a PDF.
For OSD NC Managers
If not already done, your respective National Committee Administrator will create your profile via
Symphony (https://symphony.iec.ch) as an OSD NC Manager to oversee the comment resolution
process for the preparation of your national comments. Once you have been granted access via
Symphony, please use your usual IEC credentials to access the link.
If you do not have access, please contact your National Committee Administrator or our OSD support
team.
For OSD NC Commenters
If not already done, your OSD NC Manager will create your profile via Symphony as an
OSD NC Commenter. Once you have been granted access via Symphony, please use your usual
IEC credentials to access the link. You may then provide your comments directly in the OSD.
As an alternative solution, OSD NC Commenters who wish to continue using the IEC comment form
can use the regular template together with a PDF of the draft document downloadable from the OSD
platform. However, please note that line numbers are no longer available, and it is not possible to add
tables and graphics or use track changes.
For Voters
Once all your national comments have been resolved, it is no longer necessary to upload the
comment form to the IEC Voting System anymore. Instead, please use the following radio buttons in
the IEC Voting System to indicate whether or not your National Committee has submitted comments
in the OSD:
Before the CDV closing date, please cast your vote – In favour, Against, Abstain – to indicate your
national position in the traditional way, using the IEC Voting System.
Comment: ☐ No Comment at this stage ☐ Comments in OSD
Reference materials
We recommend that OSD NC Managers and OSD NC Commenters review the available materials to
better understand the member commenting on the OSD platform. This includes:
• latest videos and presentations on the OSD webpage, and
• step-by-step explanations on Helpscout.

How to download PDF file
This link will lead you to the Online Standards Development (OSD) platform where you may download
the PDF file by following the steps shown below.
How to receive the Word file
Should your national mirror committee wish to receive the Word file for translation purposes only,
please contact our OSD support at osd_support@iec.ch.
Translation integration mechanisms for OSD documents are still being studied for development. The
solution above is a temporary measure.
Contact
Should you require any assistance, please contact the OSD project team at osd_support@iec.ch.

INTERNATIONAL ELECTROTECHNICAL COMMISSION
____________
Piezoelectric sensors - Part 2: Chemical and biochemical sensors –
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 itself does not provide any attestation of conformity. Independent certification bodies
provide conformity assessment services and, in some areas, access to IEC marks of
conformity. IEC is not responsible for any services carried out by independent certification
bodies.
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) IEC draws attention to the possibility that the implementation of this document may involve
the use of (a) patent(s). IEC takes no position concerning the evidence, validity or applicability
of any claimed patent rights in respect thereof. As of the date of publication of this document,
IEC [had/had not] received notice of (a) patent(s), which may be required to implement this
document. However, implementers are cautioned that this may not represent the latest
information, which may be obtained from the patent database available at
https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent
rights.

International Standard IEC 63041‑2 has been prepared by subcommittee 13: Sensor devices
and systems, of IEC technical committee TC 49: Piezoelectric, dielectric and electrostatic
devices and associated materials for frequency control, selection and detection. It is an
International Standard.
This second edition cancels and replaces the first edition published in 2017. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The term “SOURCE” of the definition has been added based on IEC TS 61994-5:2023.
The text of this International Standard is based on the following documents:
