Overview

EN IEC 60598-2-22:2022 - "Luminaires - Part 2-22: Particular requirements - Luminaires for emergency lighting" - specifies safety and performance requirements for emergency luminaires intended for use with electrical lamps powered from emergency supplies up to 1 000 V. The standard provides general requirements for emergency lighting equipment, clarifies terminology (the term lamp includes light sources), and is intended to be used together with EN IEC 60598-1 (general luminaire requirements). It does not cover effects of non-emergency voltage reductions on luminaires that incorporate high-pressure discharge lamps.

Key topics and technical requirements

This part of IEC 60598 addresses the full lifecycle of emergency luminaires through tests, documentation and construction requirements. Key topics include:

• Scope and definitions - application limits, meanings of terms used for emergency lighting.
• General test requirements - test methods to verify compliance with safety and performance clauses.
• Classification and marking - required product identification, safety markings and labelling for safe use and maintenance.
• Construction and wiring - mechanical design, internal/external wiring, terminals and earthing provisions.
• Protection against electric shock - design measures to protect users and maintenance personnel.
• Creepage/clearance and insulation - electrical separation and dielectric strength requirements.
• Endurance and thermal tests - thermal behaviour and durability under normal and emergency operation.
• Resistance to dust, moisture and ingress - environmental robustness including IP aspects (resistance to dust and moisture).
• Insulation resistance, electric strength and fire resistance - dielectric strength, tracking and heat/fire resilience.
• Photometric requirements and data - requirements for photometric data and distribution relevant to emergency performance.
• Changeover operation and battery/backup interfaces - behaviour when switching to emergency power and compatibility with batteries, controlgear and charge/discharge systems.

Practical applications and users

EN IEC 60598-2-22:2022 is essential for:

• Luminaire manufacturers designing and certifying emergency lighting products.
• Lighting designers and specifiers ensuring emergency luminaires meet safety and photometric requirements.
• Test laboratories and conformity assessors performing endurance, thermal and electrical tests.
• Installers and facility managers selecting compliant luminaires for buildings, escape routes and public spaces.
• Regulators and procurement teams seeking harmonized standards to demonstrate conformity with the Low Voltage Directive (2014/35/EU) and related safety objectives.

Related standards

This part references and works with other standards, for example:

• EN IEC 60598-1 (general requirements for luminaires)
• IEC lamp controlgear parts (e.g., IEC 61347-2-7, IEC 61347-2-13)
• Battery and cell safety standards (e.g., IEC 62133-2, IEC 61951 series)
• IEC 62034 (automatic test systems for emergency escape lighting)

EN IEC 60598-2-22:2022 helps manufacturers and stakeholders ensure safe, reliable and legally aligned emergency lighting solutions.

A-deviations
A-deviation: National deviation due to regulations, the alteration of which is for the time being outside
the competence of the CEN-CENELEC national member.
This European Standard falls under Directive 2006/95/EC.
NOTE (from CEN-CENELEC IR Part 2:2011, 2.17) Where standards fall under EU Directives, it is the view of the
Commission of the European Communities (OJ No C 59; 1982-03-09) that the effect of the decision of the Court
of Justice in case 815/79 Cremonini/Vrankovich (European Court Reports 1980, p. 3583) is that compliance with
A- deviations is no longer mandatory and that the free movement of products complying with such a standard
should not be restricted except under the safeguard procedure provided for in the relevant Directive or
Regulation.
A-deviations in an EFTA-country are valid instead of the relevant provisions of the European Standard
in that country until they have been removed.

Annex ZZ
(informative)
Relationship between this European standard and the safety objectives
of Directive 2014/35/EU [2014 OJ L96] aimed to be covered
This European Standard has been prepared under a Commission’s standardization request relating to
harmonized standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means
of conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the
Council of 26 February 2014 on the harmonization of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
[2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding safety objectives of
that Directive, and associated EFTA regulations.

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
