Overview

IEC 60598-2-5:2015 is an international standard issued by the International Electrotechnical Commission (IEC) that defines particular requirements for floodlights. This standard applies to luminaires designed for floodlighting using electrical light sources operating on supply voltages up to 1,000 V. The third edition, published in 2015, replaces the previous 1998 edition, featuring important technical updates, notably the introduction of requirements for a glass breaking test. This revision ensures enhanced safety and durability standards for floodlights in diverse environments.

Key Topics

• Scope and Application: Specifies requirements for floodlights for both indoor and outdoor environments, ensuring suitability for electrical sources on voltages not exceeding 1,000 V.

• Construction Requirements:

  • Floodlights intended for outdoor use must provide at least IPX3 protection against moisture ingress.
  • Structural components such as lampholder brackets and lamp supports must withstand normal usage throughout the product's life.
  • Secure attachment to supports withstanding wind speeds of up to 150 km/h is mandatory for outdoor floodlights.
  • Fixings must prevent dislodgement due to vibration, with particular attention to safety for floodlights mounted at heights of 3 meters or more.

• Marking and Documentation:

  • Besides general marking requirements, manufacturers must provide detailed information, including operating position, weight, dimensions, and mounting limitations, to ensure safe and correct installation.

• Mechanical and Safety Tests:

  • Compliance includes endurance, thermal, insulation resistance, and mechanical impact tests.
  • The glass breaking test addresses the risk of hazardous glass particle release under stress.
  • Wind load tests with sandbags simulate real-world mechanical stresses to assess fixing integrity.

• Classification and Definitions:

  • The standard harmonizes classification criteria with IEC 60598-1.
  • Defines floodlighting as the lighting of a scene or object to increase illuminance relative to surroundings, typically using projectors or floodlights.

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.
International Standard IEC 60598-2-5 has been prepared by subcommittee 34D: Luminaires, of

c) maximum projected area of the floodlight;.
d) limitation of use indoors and/or outdoor;
e) maximum mounting height if ≤ 5 m, relevant to the selected method for protection against
the falling of glass particles and the number of fixing devices.
5.6 Construction
The provisions of Section 4 of IEC 60598-1 apply together with the requirements of 5.6.1
to 5.6.8.
5.6.1 Floodlights for use outdoors shall have protection against the ingress of moisture at
least equivalent to IPX3.
5.6.2 Lampholder brackets and lamp supports where used shall withstand normal usage
throughout the life of the floodlight. They shall accept and retain lamps which are within the
dimensional tolerances stated in the appropriate IEC publication where applicable, and locate
the lamp or lamps in the designed relationship to the optical control devices in the floodlight.
5.6.3 When provision is made for alternative sizes of lamps or light centre positions, the
adjusting means shall be positive and firmly retained in the selected position.
5.6.4 Refractors, reflectors or any other light controlling components shall be so marked or
constructed that they can be fitted or replaced only in the correct relationship to the light
source.
5.6.5 The means for attaching the floodlight to its support shall be appropriate to the weight of
the floodlight.
For floodlights for use above ground level outdoors, the connection shall withstand wind
speeds of 150 km/h on the projected surface of the floodlight assembly without undue
deflection.
Fixings which carry the weight of the floodlight and internal accessories shall be provided with
appropriate means to prevent the dislodgement of any part of the floodlight by vibration, either
in service or during maintenance.
Parts of floodlights for mounting heights of 3 m or higher which are fixed other than with at
least two devices, for example, screws or equivalent means of sufficient strength, shall have
such extra protection as to prevent those parts falling and endangering persons, animals and
surroundings, if a fixing device fails under normal conditions. The points of attachment which
allow the floodlight to rotate and which are tested below are excluded from the requirements of
this paragraph.
Compliance shall be checked by inspection and, for floodlights for use above ground level
outdoors, by the additional following test.
The floodlight is mounted with its largest projected area as viewed in elevation lying in the
horizontal plane, and with the means of attachment secured in accordance with the
manufacturer's recommendations.

– 8 – IEC 60598-2-5:2015 © IEC 2015
For floodlights for use above ground level outdoors, a constant evenly distributed load is
applied for 10 min on the floodlight using sand-bags providing 2,4 kN per square metre of
floodlight projected area. The floodlight is then turned 180° in the vertical plane, about the point
of attachment, and the test is repeated.
During the test there shall be no failure or movement about the point of attachment and after
either part of this test there shall be no permanent set exceeding 1°.
5.6.6 Where means for angular adjustment are provided, there shall be provision for positive
locking after any such adjustments have been effected.
5.6.7 Floodlights for use outdoors shall be resistant to the vibrations which may occur during
normal use.
5.6.8 In order to reduce the risk of injury caused by breaking glass, the following
requirements, in relation to the intended mounting height of the luminaire, are applicable.
When luminaires are installed below 5 m, no additional requirements are requested on glass
covers.
When luminaires are installed above 5 m, glass covers shall be:
a) constituted with a glass that fractures into small pieces,
b) constituted with a glass having a high impact shock resistance, or
c) protected by any means to retain glass fragments in case of breakage (e.g. guard, film
coating).
Compliance is checked:
– for a) by test and inspection according to 5.6.8.1;
– for b) by test and inspection according to 5.6.8.2;
– for c) by inspection.
The luminaire manufacturer shall declare to the testing laboratory the method of protection
used.
5.6.8.1 Protection by the use of glass that fractures into small pieces
Preconditioning of the luminaire and glass cover before testing is not required.
For flat glass, the glass component is supported over the whole area to ensure that particles
will not be scattered upon fragmentation and that movement of the particles is prevented.
Shatter the glass with a centre punch at a point 30 mm from the mid-point of one of the longer
edges of glass towards the centre.
NOTE 1 A centre punch is a tool made of steel with a sharp point.
For formed glass, the glass component part shall be supported on all the surfaces (example of
testing method could be the use of material like sand or a mould). The thickness of the
material used as a support surface shall be more than 30 mm. The face of the glass shall be
completely covered with an adhesive film in order to avoid any movement of the broken
particles. Shatter the glass (from the inside or the outside) with a centre punch in the middle of
the glass cover.
Within 5 min of fracture, count the particles in a 50 mm square, located approximately at the
centre of the area of the coarsest fracture but always within the confines of the glass.

Compliance: A glass is deemed to have passed the test if the number of particles in the 50 mm
square is more than 40; glass splinters and pieces less than the full thickness of the glass
being excluded from the count. For glass of smaller size where a 50 mm × 50 mm area is not
possible, the number of pieces necessary in the count is proportionately reduced. The size of
the particles shall be less than 50 mm for all the dimensions.
In the count of the total number of particles in the 50 mm square, the particles in the centre of
the square plus those at the edge shall be taken into account. In order to count particles at the
edge of the square, it is recommended that all pieces intersected by two adjacent sides be
included and all particles intersected by the two other sides be ignored (see Figure 1). Where
possible, the area of measurement should not be within 30 mm of any edge, hole or machining
of the glass or in a circle of 50 mm around the impact.

NOTE 2 A suitable method of counting the particles is to place a square of 50 mm side, of transparent material
over the glass and mark a spot of ink as each particle within the square counted.
NOTE 3 When the test sample remains as one sheet, the fragmentation lines would normally be used to indicate
fractures and the size and number of particles would thus be evaluated, unless reinforcing or a film were employed.

5.6.8.2 Protection by the use of high impact resistant glass
5.6.8.2.1 Glass covers shall have high mechanical strength.
The luminaire and glass cover shall be preconditioned by the thermal endurance test of 12.3 of
IEC 60598-1.
The test is performed on one sample and on the external face (opposite side of the lamp) of
the glass mounted on the luminaire.
The testing procedure shall be in accordance with the IEC 62262, and the test apparatus used
is the pendulum hammer or vertical hammer according to IEC 60068-2-75.
Compliance: The glass shall not be broken after a shock with impact energy of 5 J (equivalent
to IK08 according to IEC 62262).
5.6.8.2.2 Glass covers shall not break into large pieces.
Glass covers shall be tested according the same testing procedure as 5.6.8.1.
Compliance: A glass is deemed to have passed the test if the number of particles in the 50 mm
square is more than 20, glass splinters and pieces less than the full thickness of the glass
being excluded from the count. For glass of smaller size where a 50 mm × 50 mm area is not
possible, the number of pieces necessary in the count is proportionately reduced. The size of
the particles shall be less than 50 mm for all the dimensions.
