Radio data system (RDS) - Receiver products and characteristics - Methods of Measurement
IEC 62634:2015 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. This second edition cancels and replaces the first edition published in 2011 and constitutes a technical revision. It includes the following changes: - the 100 kHz test measurement case from Clause 8 of IEC 62634:2011 was deleted as it did not permit to achieve stable and reproducible measurement results; - an error has been corrected. The term "de-emphasis" shall read correctly "pre-emphasis".

L'IEC 62634:2015 décrit les exigences minimales de performance des récepteurs RDS, qui concernent trois catégories de récepteurs RDS et leur mesure. Il convient néanmoins de noter qu'il existe aussi sur le marché des récepteurs RDS qui dépassent largement les exigences minimales de performances indiquées ici pour les récepteurs RDS. Cette deuxième édition annule et remplace la première édition publiée en 2011. Elle constitue une révision technique. Elle inclut les modifications suivantes: - le cas de mesure d'essai à 100 kHz tiré de l'Article 8 de l'IEC 62634:2011 a été supprimé car il ne permettait pas d'obtenir des résultats de mesure stables et reproductibles; - une erreur a été corrigée. À la place du terme "désaccentuation", il faut lire "préaccentuation".
Radijski podatkovni sistem (RDS) - Izdelki za sprejemnike in karakteristike - Merilne metode (IEC 62634:2015)
Ta mednarodni standard opisuje načine za merjenje minimalnih zahtev glede zmogljivosti sprejemnikov RDS, ki zadevajo tri kategorije izdelkov sprejemnikov RDS. Treba pa je poudariti, da so na trgu tudi sprejemniki RDS, ki znatno presegajo navedene minimalne zahteve glede zmogljivosti sprejemnikov RDS. Metode in algoritmi za doseganje samodejnega sledenja programskih storitev prek seznamov AF so odvisne od odjemalca in proizvajalca in zato niso zajete v tem standardu.

AND CHARACTERISTICS – METHODS OF MEASUREMENT
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
