General Information
Overview
EN IEC 61557-17:2021 (also published as IEC 61557-17:2021) sets minimum performance and construction requirements for non‑contact AC voltage indicators used in low‑voltage distribution systems (up to 1 000 V AC and 1 500 V DC). The standard’s primary aim is to reduce the risk of electric shock caused by incorrect interpretation of an indicator’s output. It is intended for products used by electrically skilled persons and explicitly states that non‑contact indicators are not designed for testing the absence of operating voltage.
Key topics and technical requirements
- Scope and user: Devices covered are non‑contact AC voltage indicators for use by trained personnel; misuse risk is addressed in requirements and testing.
- Performance requirements: Defines minimum sensitivity, repeatability and operating uncertainty (B and B [%]) to quantify triggering behaviour and uncertainty of indication.
- Trigger‑point and indication tests: Procedures to determine and verify the voltage level at which indicators respond (trigger point), plus optical visibility tests for the indicator output.
- Safety requirements: Mechanical strength tests, safety evaluation (in line with IEC 61557‑1), and specific safety tests to reduce shock risk to operators and bystanders.
- Battery test facility: Requirements for built‑in battery test or indication to avoid false negatives from depleted batteries.
- Electromagnetic compatibility (EMC): Immunity and emission requirements (referenced to IEC 61326‑1) to ensure reliable operation in real electrical environments.
- Marking and operating instructions: Mandatory labelling and user guidance to prevent misuse and explain limitations (for example, not suitable for absence-of-voltage testing).
- Type testing and conformity: Test sequence includes mechanical, indication, visibility, safety and EMC tests as part of type approval.
Applications and users
- Used by electricians, maintenance technicians, installation engineers and inspection teams for quick detection of live AC conductors in low‑voltage environments.
- Typical use cases: preliminary live voltage checks, troubleshooting, identifying live phases and verifying presence of AC voltage where non‑contact detection is appropriate.
- Important: For confirming absence of hazardous voltage, a 2‑pole low‑voltage detector compliant with IEC 61243‑3 should be used instead.

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.
