Attention IEC-CENELEC parallel voting
The attention of IEC National Committees, members of
CENELEC, is drawn to the fact that this Committee Draft
for Vote (CDV) is submitted for parallel voting.
The CENELEC members are invited to vote through the
CENELEC online voting system.
This document is still under study and subject to change. It should not be used for reference purposes.
Recipients of this document are invited to submit, with their comments, notification of any relevant patent rights
of which they are aware and to provide supporting documentation.
Recipients of this document are invited to submit, with their comments, notification of any relevant “In Some
Countries” clauses to be included should this proposal proceed. Recipients are reminded that the CDV stage is
the final stage for submitting ISC clauses. (SEE AC/22/2007 OR NEW GUIDANCE DOC).

NOTE FROM TC/SC OFFICERS:
download this electronic file, to make a copy and to print out the content for the sole purpose of preparing National
Committee positions. You may not copy or "mirror" the file or printed version of the document, or any part of it,
for any other purpose without permission in writing from IEC.

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.
