Overview

SIST EN 55016-1-6:2015/prA3 (Frag 4):2026 is an amendment to the internationally recognized series on Electromagnetic Compatibility (EMC) standards. Produced by the Slovenian Institute for Standardization (SIST), this fragment focuses on the calibration of EMC antennas, specifically addressing Normalized Site Attenuation (NSA). NSA is a critical parameter to ensure accurate radio disturbance measurements, supporting compliance with EMC requirements in electrical and electronic equipment.

This standard aligns with EN 55016-1-6:2015/prA3 at the European level and incorporates updates from CISPR 16-1-6, making it essential for laboratories involved in antenna calibration, EMC testing, and site validation processes.

Key Topics

• EMC Antenna Calibration: Details antenna calibration methods relevant to electromagnetic interference (EMI) and immunity measurements, focusing on performance in the 30 MHz to 1 GHz frequency range.
• Normalized Site Attenuation (NSA): Provides updated guidance on NSA calculations, ensuring consistent and repeatable EMC testing environments.
• Correction Factors and Measurement Uncertainty: Clarifies new correction factors for biconical antennas, updates key tables and figures, and addresses uncertainty contributions from various antenna measurement parameters.
• Technical Revisions: Reflects changes recommended by the CISPR working group, particularly in data tables, antenna model diagrams, and the preferred use of 4:1 (200 Ω) baluns due to their lower frequency variation in correction factors.
• Figures and Tables: Adds updated figures for biconical antenna sections and dimensions, supporting more accurate geometric and electrical calibration.

Applications

This standard is vital for:

• EMC Test Laboratories: Enables accurate antenna calibration and validation of open-area test sites (OATS), semi-anechoic chambers, and related environments.
• Compliance Assessment: Facilitates the qualification of sites and measurement systems according to international EMC criteria, a requirement for product certification and market access.
• Equipment Manufacturers: Assists manufacturers in verifying that their EMC test setups meet updated standards, reducing the risk of non-compliance during product assessments.
• Calibration Service Providers: Ensures professionals use internationally harmonized methods for antenna factor correction and site validation, improving confidence and reliability in issued calibration certificates.
• Regulatory Authorities and Inspectors: Provides a reference for verifying that accredited laboratories apply current, standardized procedures in their assessments and reports.

Related Standards

If you are working with antenna calibration, EMC measurements, or compliance testing, consider referencing these related standards:

• EN 55016 Series: Specification for radio disturbance and immunity measuring apparatus and methods - the foundational EMC measurement standard series in Europe.
• CISPR 16-1-6: The international counterpart to EN 55016, focusing on antenna calibration procedures for EMC.
• ISO/IEC 17025: General requirements for the competence of testing and calibration laboratories, often cross-referenced in EMC testing and antenna calibration contexts.
• EN 50147-1: Specific site validation and NSA measurement procedures for OATS and anechoic chambers.
• EN 61000-4-x: Additional standards for testing immunity to electromagnetic disturbances.

By adhering to SIST EN 55016-1-6:2015/prA3 (Frag 4):2026, organizations ensure high confidence in radio disturbance measurements, meeting both European and international EMC testing requirements. This amendment delivers essential updates to antenna calibration routines, supporting accuracy, repeatability, and global conformity in EMC assessments.

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 has 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. IEC
49 shall not be held responsible for identifying any or all such patent rights.
