Overview

EN 60315-4:1998/A1:2026 is an international standard from CLC, prepared in alignment with IEC guidelines, that details test methods for evaluating the performance of radio receivers designed for frequency-modulated (FM) sound broadcasting emissions. This standard is critically relevant to manufacturers and testing bodies in the audio, broadcast, and multimedia sectors. The amendment ensures the ongoing relevance and accuracy of testing methods in a landscape influenced by technological advances and regulatory changes.

The main focus is to provide standardized procedures for assessing how FM radio receivers handle selectivity and rejection of adjacent channel signals, using precise measurement techniques. Applying this standard supports international market access and helps guarantee a high quality of service for end users.

Key Topics

EN 60315-4:1998/A1:2026 covers vital aspects in measuring and qualifying FM sound broadcasting receivers, including:

  • Selectivity Measurement: Defines test setups for evaluating a receiver's ability to distinguish between the desired (wanted) signal and nearby (unwanted) interfering signals. This involves tests using both sinusoidal signal and coloured noise modulation.
  • Signal-to-Interference Ratio (S/I Ratio): Measurement procedures are established to determine the ratio of audio output signals with and without interference, at specific frequency offsets from the wanted signal.
  • Adjacent and Alternate Channel Rejection: Procedures for measuring how effectively the receiver rejects signals on frequencies immediately adjacent to, or spaced further apart from, the desired frequency.
  • Standard Test Conditions: Specifies the configuration of test equipment, such as combining networks or artificial antennas, and outlines standard modulating signals and test setups to ensure consistent and repeatable results.
  • Data Presentation: Guidance on plotting results, showing how the S/I ratio and wanted signal level vary with frequency separation between desired and interfering signals, and how to document and interpret the findings.

Applications

This standard and its amendment are widely adopted in several practical contexts:

  • Receiver Manufacturing: Used by radio and audio electronics manufacturers to design and certify FM receivers, ensuring compliance with international requirements on selectivity and interference rejection.
  • Quality Assurance and Laboratory Testing: Applied by test laboratories and certification bodies to assess the conformity of new radio receivers before market introduction or regulatory approval.
  • Broadcast Engineering: Assists broadcasters, network planners, and frequency managers in understanding the receiver performance required to meet quality of service objectives, particularly in dense signal environments.
  • Regulatory Compliance: Provides a harmonized framework for demonstrating that FM receiver products meet technical standards mandated in various jurisdictions, supporting cross-border trade and consumer protection.

Related Standards

The following standards are closely aligned with EN 60315-4:1998/A1:2026 and may be referenced for comprehensive test coverage or specialized measurement techniques:

  • IEC 60315-1 - General methods of measurement on radio receivers
  • ITU-R BS.468-4 - Standard for measuring audio-frequency interference using specific weighting networks
  • EN 55020 / CISPR 20 - Sound and television broadcast receivers and associated equipment - Immunity characteristics
  • EN 60065 / IEC 60065 - Audio, video and similar electronic apparatus - Safety requirements

Adopting EN 60315-4:1998/A1:2026 ensures FM radio receivers meet internationally recognized levels of performance, selectivity, and robustness, aiding in device reliability, regulatory conformity, and user satisfaction. This standard remains a cornerstone for those involved in FM receiver production, testing, and certification.

9 sound broadcasting emissions
13 FOREWORD
14 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
15 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
16 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
17 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
18 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
19 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
20 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
21 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
22 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
23 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
24 consensus of opinion on the relevant subjects since each technical committee has representation from all
25 interested IEC National Committees.
26 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
27 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
28 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
29 misinterpretation by any end user.
30 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
31 transparently to the maximum extent possible in their national and regional publications. Any divergence between
32 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
33 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
34 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
35 services carried out by independent certification bodies.
36 6) All users should ensure that they have the latest edition of this publication.
37 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
38 members of its technical committees and IEC National Committees for any personal injury, property damage or
39 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
40 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
41 Publications.
42 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
43 indispensable for the correct application of this publication.
44 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
45 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
46 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
47 may be required to implement this document. However, implementers are cautioned that this may not represent
48 the latest information, which may be obtained from the patent database available at https://patents.iec.ch [and/or]
49 www.iso.org/patents. IEC shall not be held responsible for identifying any or all such patent rights.
50 Amendment 1 to IEC 60315-4:1997 has been prepared by subcommittee TA1: Terminals for
51 audio, video and data services and content, of IEC technical committee TC100: Audio, video
52 and multimedia systems and equipment.
