Radio data system (RDS) - Receiver products and characteristics - Methods of measurement
IEC 62634:2011 describes how to measure minimum RDS receiver performance requirements which concern three RDS receiver product categories. 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 customer- and manufacturer-specific, and are therefore not covered in this standard. It 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.

La CEI 62634:2011 décrit les exigences minimales de performance des récepteurs RDS, qui concernent trois catégories de produits de récepteurs RDS. Il convient de noter qu'il existe sur le marché des récepteurs RDS qui dépassent largement les exigences minimales de performances indiquées ici pour les récepteurs RDS. Les méthodes et algorithmes utilisés pour le suivi automatique des stations au moyen des listes AF sont spécifiques aux clients et aux fabricants; par conséquent, cet aspect est volontairement exclu de la présente norme. Cette publication annule et remplace la CEI 60315-9, publiée en 1996, et constitue une révision technique. Les modifications principales par rapport à la CEI 60315-9 sont les suivantes: - utilisation de méthodes de mesure conformes à l'état de l'art avec des produits RDS actuels; - indication d'objectifs de performances réalistes; - complémentarité à la norme sur le système RDS, CEI 62106 (2009), traitement des conditions de réception RDS difficiles 'signal faible', 'canal adjacent' et 'signal fort' pour confirmer les exigences de sensibilité et de sélectivité pour trois catégories différentes de produits RDS.
Radijski podatkovni sistem (RDS) - Izdelki za sprejemnike in karakteristike - Merilne metode (IEC 62634:2011)
Ta mednarodni standard opisuje, kako meriti minimalne zahteve delovanja sprejemnikov RDS,
ki se nanašajo na tri proizvodne kategorije sprejemnikov RDS. Treba pa je
opozoriti, da so na trgu tudi izdelki za sprejemnike RDS, ki precej prekašajo
navedene minimalne delovne zahteve sprejemnika RDS.
Metode in algoritmi za doseganje avtomatske programske storitve – po seznamih
AF – pa so zelo specifični za stranko in proizvajalca, zato niso zajeti v tem standardu.

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.
