Overview

SIST EN IEC 61326-2-3:2021 sets out the electromagnetic compatibility (EMC) requirements for transducers with integrated or remote signal conditioning, focusing on specific test configurations, operational conditions, and performance criteria. Developed by the Slovenian Institute for Standardization (SIST), this standard aligns with the international IEC 61326-2-3:2020 edition and supersedes previous versions. It applies to electrical equipment used for measurement, control, and laboratory purposes, ensuring reliable performance of transducers under electromagnetic disturbances.

The standard primarily covers transducers capable of transforming non-electrical quantities into process-relevant electrical signals, essential for industrial process automation, laboratory analysis, and control systems. It addresses both integrated and remote signal conditioning units and encompasses transducers for electrochemical and biological measurements.

Key Topics

  • Scope of Application

    • Applies to transducers converting non-electrical quantities (e.g., temperature, pressure, force) into electrical signals, using an auxiliary energy source.
    • Covers both integrated (all functional components in one enclosure) and remote (components in separate enclosures) signal conditioning.
    • Includes transducers powered by AC, DC, batteries, or internal sources.
  • EMC Test Configuration

    • Specifies detailed requirements for configuring equipment under test (EUT) to ensure that EMC evaluations are meaningful and repeatable.
    • Covers requirements for monitoring systems, installation practices, and distance from the EUT to reduce interference.
    • Addresses grounding and shielding techniques for test setups.
  • Operational Conditions

    • Details the operating states and environmental conditions under which transducers must be evaluated.
    • Requires testing under varying power supply scenarios (standalone battery operation, external power supply).
    • Mandates simulation of input signals where direct application is not feasible.
  • Performance Criteria

    • Defines functional performance benchmarks for transducers under EMC disturbances (immunity, emission).
    • Establishes acceptance criteria for main measurement functions, communication, and alarm outputs.
    • Requires documentation of allowable deviations and recovery times post-testing.
  • Special Considerations

    • Additional annexes specify requirements for particular types of transducers, such as those measuring force, pressure, or temperature.
    • Offers guidance on simulation techniques for testing when direct application of physical quantities is impractical.

Applications

  • Process Automation: Ensures accurate and reliable signal conversion for process measurement and control systems in industrial settings.
  • Laboratory Equipment: Promotes consistent operation of transducers in high-precision measurement environments, such as analytical laboratories.
  • Field Measurement & Monitoring: Validates the performance of portable or fixed sensors in real-world environments subject to varying EMC conditions.
  • Electrochemical and Biological Measurement: Supports compliance for specialized sensors used in chemical processing, environmental monitoring, and biotechnology.

Organizations adopting this standard benefit from enhanced reliability, reduced downtime due to EMC issues, and easier conformity assessment for regulatory purposes.

Related Standards

  • IEC 61326-1:2020 - General EMC requirements for electrical equipment for measurement, control, and laboratory use; forms the baseline for this part.
  • Other Parts of IEC 61326 Series - Cover particular requirements for other types of measurement and control equipment.
  • Regional Adaptations - EN IEC 61326-2-3:2021 as a direct European adoption; other countries may have equivalent national standards.

Implementing SIST EN IEC 61326-2-3:2021 ensures robust EMC design and assessment for transducers with integrated or remote signal conditioning, facilitating compliance with international and European market requirements in electromagnetically challenging environments.

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.
