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) 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.
International Standard IEC 62634 has been prepared by technical area 1: Terminals for audio,
video and data services and content, of IEC technical committee 100: Audio, video and
multimedia systems and equipment.
International Standard IEC 62634 cancels and replaces IEC 60315-9, published in 1996, and
constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC 60315-9:
– use of state-of-the-art measuring methods based on today’s RDS products,
– provision of realistic performance targets,
– is complementary to RDS standard IEC 62106 (2009),
– it covers the challenging RDS receiving conditions “weak signal”, “adjacent channel” and
“strong signal” to verify the required RDS sensitivity and selectivity for three different RDS
product categories.

INTRODUCTION
This International Standard gives commonly agreed measuring methods to complement the
RDS standard IEC 62106 (2009) and the RBDS standard (NRSC-4-A) in the USA.
The RDS measuring methods presented here are directed at all manufacturers of RDS
receiver products, and in particular tuner modules with embedded RDS functionality, including
TMC (see ISO 14819 series of standards).

METHODS OF MEASUREMENT



1 Scope
This International Standard describes how to measure minimum RDS receiver performance
requirements which concern three RDS receiver product categories. However, it should be
noted that there are also RDS receiver products on the market that significantly out-perform
the minimum RDS receiver performance requirements quoted.
Methods and algorithms to achieve automatic programme service-following by means of AF
lists are, however, very customer- and manufacturer-specific, and are therefore not covered in
this standard.
