Overview

IEC 62034:2012 is an internationally recognized standard published by the International Electrotechnical Commission (IEC) focusing on automatic test systems (ATS) for battery powered emergency escape lighting. This standard defines the essential performance, safety, and functional requirements for ATS components and complete systems designed to monitor and test emergency lighting installations operating at supply voltages up to 1,000 V.

The second edition of IEC 62034 replaced the 2006 version, providing technical revisions that clarify compliance criteria, enhance the understanding of system requirements, and update normative references. Its purpose is to ensure the reliability and continuous readiness of emergency lighting systems, critical for safe evacuation during emergencies.

Key Topics

INTRODUCTION
Emergency lighting systems are a safety related product; their correct performance can only
be assured by systematic testing and maintenance. Conventional techniques for testing are
reliant upon manual testing procedures, and are highly susceptible to neglect. These
limitations of conventional techniques can be overcome by automating the testing process. It
is essential that automatic testing systems for emergency luminaires schedule tests reliably,
and provide timely notification of failures or degradation of performance.
Automatic test systems (ATS) will still require manual intervention to correct faults when they
are identified, and procedures should be put in place for such intervention. These systems
provide information to assist users to manage risk on their premises.
Automatic test systems for emergency escape lighting assist the operator of the building by
showing the results of tests that will have been made at prescribed intervals, without
disrupting any other electrical services. It is essential that the notification of failures or
reduction in performance be given at the earliest opportunity to enable the emergency escape
system to be restored to full operation.
The automatic test system will provide those responsible for an emergency lighting installation
with information to enable them to ensure that the installed luminaires operate correctly when
required.
The automatic test system may be part of a building management system (BMS) for making
the emergency lighting tests; this standard would only apply to the emergency lighting testing
part of a BMS.
A visual check of system components and indicators should be included in the routine of
safety staff. This check should be made regularly to ensure that the emergency luminaire is
present and intact, with lamps and indicators working and visible i.e. not obscured, covered or
painted.

In all ATS types (see Annex B), any failure of the progress of the test sequence of the ATS
shall be indicated locally on the luminaire and/or on the remote panel as applicable to the
ATS type.
NOTE The monitoring of the timing circuit is essential as the duration of testing periods and the intervals between
them need to be ensured and maintained.
This failure shall be tested by simulating a fault that interrupts the progress of the test
sequence or any other procedure that can be agreed with the system designer/manufacturer
and the test laboratory to demonstrate compliance with this clause, and checking that the
failure is indicated locally on the luminaire and/or on the remote panel as applicable to the
ATS type.
Compliance is checked by testing a sample according to the instructions provided by the
manufacturer.
4.3 Functional requirements
NOTE The tests of 4.3 and 4.4 should be carried out before the tests of Clause 5.
4.3.1 The automatic test system (ATS)
The ATS shall check the functional operation of the emergency lighting luminaires and
associated power supplies, at intervals and for the duration specified in Clause 5, to identify
any faults that would impair their operational duty. Any faults shall be indicated or reported

– 10 – 62034 © IEC:2012
within 24 h after their detection. For types P, ER, PER and PERC, verification for a fully
loaded system may be made by extrapolation of the polling rate measured on the individual
unit.
NOTE Types P, ER, PER and PERC are defined in Annex B.
Compliance is checked by inspection and prescribed test (see Clause 5).
4.3.2 Emergency battery supply
The test system shall check and indicate if the emergency battery supply has failed.
Compliance is checked by disconnecting the battery during the test sequence – a fault shall
be indicated within the test period.
4.3.3 Lamps tested in the emergency mode
The test system shall check that any changeover device, where fitted, has powered the lamp
from the emergency power supply.
NOTE The full load from the battery is equivalent to the maximum discharge load current of the circuit, excluding
the starting period.
Compliance is checked as follows:
• if the charging current to the battery is higher than 15 % of the full load, the charger shall
be disconnected during the test;
• if the charging current is between 5 % and 15 % of the full load, the charger shall be
compensated during the test;
• if the charging current is less than 5 % of the full load, the charger should be ignored
during the test.
4.3.4 Maintained luminaires tested in emergency mode and in normal mains
condition
For maintained luminaire that do not have a changeover device, the test system shall check
that the lamp operates correctly in both the normal mains supply and failed supply conditions.
For maintained luminaries with a changeover device, test shall be carried out according to
4.3.3 with the monitoring of the battery current or output voltage to check the changeover.
Compliance is checked by inspection of the test system when the maintained lamps are
operating.
4.4 System integrity
4.4.1 Protection against system part failures and faults
Any single fault or part-failure that occurs in the ATS, or within one of the system parts, shall
not affect the emergency operation of the ATS, in accordance with the requirements of 4.4.2
to 4.4.7.
Compliance is checked by inspection and the requirements of 4.4.2 to 4.4.7.

62034 © IEC:2012 – 11 –
4.4.2 Intercommunications failure
Any failure of intercommunication between the parts of ATS system, as defined in 3.3 and 3.4,
shall not inhibit the emergency operation of the luminaires connected to the ATS, or initiate an
unwanted test. Furthermore, in the case P, ER, PER and PERC ATS types (see Annex B),
any failure of intercommunication between ATS parts shall be indicated as a fault on the
remote panel within 24 h of the failure occurring.
For this test, the communication shall be interrupted by the appropriate means (according to
the manufacturer’s instructions). The following checks are then made:
– no unwanted test is initiated;
– the emergency operation of the luminaires operates if the normal supply is switched off;
– the failure of the interconnection between ATS parts is indicated as a fault on the remote
panel within 24 h.
NOTE Subclauses 22.3.18 and 22.3.21 of IEC 60598-2-22 are to be considered.
4.4.3 System interconnection
The operation of luminaires in the emergency mode shall not be affected by any faults in the
wiring of the interconnections of the ATS, including a short circuit, contacts to earth or an
interruption in the wiring of the ATS supply or communications wiring. No unwanted test shall
be initiated. The test shall only operate at correct times; other tests would put the system’s
emergency duty at risk.
Compliance is checked by simulation of these wiring faults to the ATS.
NOTE Short circuit connections between supply and communications wiring are not included in the test if they are
separated by double insulation.
4.4.4 Component failures
The failure of any single part within the ATS shall not inhibit the emergency operation of more
than one of the luminaires connected to the ATS, or initiate an unwanted test.
For component failures that mimic a control signal or inhibit an emergency operation, the
requirements of IEC 61347-1 apply.
NOTE For the ATS systems and devices, it may be appropriate to seek the advice of the control gear
manufacturers with respect to selection of the internal parts that are most likely to cause a failure against the
requirements of this test.
4.4.5 System parts compatibility
The individual parts, control gear and other electronic devices selected to form an ATS shall
be proven to be compatible with each other.
It shall be the responsibility of the system designer to ensure ATS component and procedure
compatibility. The manufacturer of ATS components/system shall provide details of
compatible system components.
– 12 – 62034 © IEC:2012
The manufacturer shall declare:
– the limits of the installation in the instruction sheet, length of the cabling, quantity of
luminaires;
– in the technical folder: the justification of compatibility between any part within the ATS.
NOTE Conformity of individual parts against the requirements of relevant IEC or regional standards cannot be
relied on to completely ensure compatibility in this instance. EMC, voltage transfer, switching phenomena, etc.
should be considered.
4.4.6 Electromagnetic immunity of the ATS
Electromagnetic phenomena shall not inhibit operation of the ATS or initiate an unwanted test.
Compliance is checked by the tests of IEC 61547 applying the requirements and compliance
criteria for emergency lighting luminaires. The IEC 61547 test report shall be provided either
by the manufacturer or a third part test house.
In addition, the supply voltage dips and interruptions tests shall be conducted in accordance
with IEC 61547. During testing, operation of the ATS shall not be affected, and no unwanted
tests shall be initiated.
4.4.7 Software failure
The correct operation of ATS software shall be proven.
It shall be the responsibility of the system designer to conduct sufficient investigations and
operational trials to ensure the correct operation of software and failure protection. Detailed
software design documentation, for example functional descriptions of the main programme
flow, flowcharts for the software operation, fault mode analysis, how the software and
hardware interact etc., shall be provided by the designer/manufacturer in order that the test
laboratory can ensure the reliability of the software.
Any software failure shall not inhibit the emergency operation of more than one of the
luminaires connected to the system, and shall not initiate an unwanted test.
NOTE For product certification (e.g. third party testing), the designer/manufacturer should have available detailed
software design documentation, including functional descriptions of the main program flow, including flow charts
fault mode analysis, etc. and how the software and hardware interact in order that the test laboratory can ensure
the reliability of the software.
Compliance is checked by inspection.
4.5 Test of emergency lamp(s)
The ATS shall check and indicate if the emergency lamp(s) do not operate in emergency
mode. In the case of P, ER, PER and PERC ATS types (see Annex B), the indication shall be
on the remote panel and possibly on the luminaries.
Compliance is checked by:
a) removal of the emergency incandescent lamp during test; and
b) the fault abnormal conditions of IEC 60598-1 for fluorescent, discharge lamps or any other
appropriate emergency lamp technology, e.g. LED.
A fault indication shall be given locally on the luminaire and/or on the remote panel as
applicable for a) and b) above.

5 Test duration and interval
5.1 Functional test
A functional test shall be performed at least once a month. For batteries, repeated tests may
entail a loss of capacity. For this reason the test duration shall be sufficient to check the
illumination of the lamp, but shall not be longer than 10 % of rated duration. For batteries that
exhibit loss of capacity from repeated short duration discharges, the total of these test
durations shall not exceed 10 % of rated duration in a month. The rated duration is defined in
IEC 60598-2-22.
NOTE 1 Attention is drawn to national regulations that may dictate the testing frequency and types of testing
required.
NOTE 2 This test gives the earliest warning of luminaire failure that is consistent with luminaire component life.
Manual logging of fault conditions, when required, should be actioned within one month or in line with national
regulations. Attention is drawn to national regulations that may require other test conditions.
NOTE 3 Proven compatibility of lamps, lamp-control gear, and the automatic test regime is the responsibility of
the system provider.
If a mains supply failure occurs before a functional test and within such a time that the battery
could not be re-charged sufficiently to run a successful functional test, then the test should be
postponed until the battery is recharged sufficiently to perform the test after the restoration of
the mains supply up to a period of 24 h. The compatibility of the final ATS parts shall ensure
their reliable operation. In the case of P, ER, PER and PERC ATS types (see Annex B) in the
event that a functional test is postponed, indication of the pending test shall be given on the
remote panel. Where applicable, the test function and test postponement functions are to be
demonstrated. If a mains supply failure occurs whilst a functional test is in progress, the test
shall be postponed and the system shall enter emergency operation. Following restoration of
the mains supply, a postponed functional test shall re-commence automatically as soon as
conditions permit. If the duration of the functional test is less than 1 % of the rated duration,
then the postponed function is not required.
The conformity of timing requirements including the periodicity and details of the tests
(hierarchy, managements of the test delays) is checked by inspection of the manufacturer’s
declaration and the technical file provided by the manufacturer.
NOTE 4 It is known that non-standardized low-power operation of fluorescent lamps can be damaging to some
types/makes of fluorescent lamp.
5.2 Duration test
For full rated duration, a test shall be performed according to the manufacturer’s instructions
at the commissioning of the ATS, and repeated automatically at least annually.
NOTE 1 The test should check that the emergency lamp(s) are illuminated for their duration of emergency
operation for the application or equivalent battery discharge rate.
NOTE 2 Attention is drawn to national regulations that may dictate the testing frequency and types of testing
required.
Random automatically-initiated rated duration tests shall be carried out within 52 weeks after
commissioning.
NOTE 3 For the use of random initiated ATS, careful consideration may be required for some applications.
The test duration shall not be able to be changed by unauthorized persons.
A duration test shall only be started when the battery supply is fully charged. If a mains supply
failure occurs whilst a duration test is in progress, the test shall be postponed and the system
shall enter emergency operation. Following restoration of the mains supply, a postponed
duration test shall re-commence automatically when the battery supply is fully re-charged.

– 14 – 62034 © IEC:2012
The design of the system should ensure this, for example by allowing a fixed delay time for
the battery supply to re-charge or by monitoring the real-time charge state of the battery). In
the case of P, ER, PER and PERC ATS types (see Annex B) in the event that a duration test
is postponed, indication of the pending test shall be given on the remote panel.
NOTE 4 In some locations, the duration test should be done always at the same settled time. In this case, the
postponed test should be launched when the battery is fully charged and at the same time as the “programmed test
+ n×24 h, where n is an integer number taking in account the time when the battery is fully charged”.
Compliance is checked, where applicable, by confirming that the test function and test
postponement functions have functioned correctly.
Conformity of timing requirements, details of operation, declaration and verification through
detailed examination of software shall be provided by manufacturers.
6 Protection of a building during the periods of test and subsequent recharge
of the emergency lighting system
6.1 General
This clause applies to all ATS types where appropriate time and dates are used to programme
the testing sequences. Manufacturer's declaration and appropriate document evidence shall
be provided.
ATS shall be designed to minimize the effects of a mains supply failure on the availability of
the emergency lighting when batteries are only partially charged as a result of a duration test
and subsequent battery recharge.
If there is a possibility that a building could be occupied during the duration test, only the
procedures in 6.3 shall be used.
6.2 Accuracy and protection of timing periods
6.2.1 General
The accuracy and the function of an ATS timer shall conform to the requirements of 6.2.2 and
6.2.3.
6.2.2 Timing accuracy
The ATS timer consists of two timing requirements – timing of test interval and timing of test
function. The accuracy of the timing of the test interval shall be tested to ensure that it has an
accuracy of ±75 s per week. The accuracy of the timing of the test function shall be tested to
ensure that it has the same accuracy as the timing of the test interval.
Compliance shall be checked by the periodicity of two successive functional tests. This
periodicity shall be stated in the instruction sheet of the manufacturer.
6.2.3 Protection of timing function
The timing function shall be retained through periods of mains supply failure or interruption for
up to 7 days, unless:
a) the ATS automatically restores separated timings of alternate luminaires;
b) the ATS is designed to provide automatic restoring for testing alternative luminaires or
automatic initiation of test function.

62034 © IEC:2012 – 15 –
Operating instructions shall state that the ATS be re-commissioned following extended
periods of mains supply failure. The extended period of mains supply failure shall be specified
by the manufacturer in the operating instructions, and shall be greater than 7 days.
Compliance is checked by:
– the simulation of a mains failure, and
– the verification of the correct functioning of the timing.
This last compliance is checked by measuring the periodicity of the functional test.
After a charging cycle of 24 h at 0,9 times the rated supply voltage, the time and the date of
the first test which occurred is noted.
Switch off the mains of the ATS during seven days.
Switch on the mains of the ATS.
The time and date of the first functional test which occurred is noted after the restoration of
the mains supply. The periodicity of the test declared by the manufacturer is checked.
In the case of a periodicity less than 1 week + 24 h, the periodicity between the first test
happening after the restoration of the normal supply and the following test is checked. The
tests shall be performed at the time and date initially scheduled before the mains interruption.
6.3 Requirements for premises that may be occupied during test and recharge
periods
6.3.1 General
Systems designed for installation in premises which may be occupied during the duration test
and subsequent battery recharge shall conform to the precautionary measures of either
a) 6.3.2 for systems of self-contained luminaires; or
b) 6.3.3 for centrally supplied systems.
NOTE At the design stage, it should be reinforced that the correct type of automatic test system should be
selected and set up to ensure testing takes place at periods of minimum risk.
6.3.2 Testing of self-contained luminaires
6.3.2.1 General
Self-contained emergency luminaires shall be tested by one of the procedures in 6.3.2.2,
6.3.2.3 or 6.3.2.4 to keep a security level of the emergency lighting in case of supply failure.
6.3.2.2 Testing alternate luminaires
The ATS shall be designed to test and allow full recharge of a luminaire prior to the testing of
the next alternate luminaire. Installation information shall be provided for each ATS by the
ATS provider.
The manufacturer shall provide sufficient information for the setting of the ATS timers to
ensure that the timing interval between adjacent luminaires is sufficiently long to prevent
drifting into the same test period.

– 16 – 62034 © IEC:2012
NOTE 1 In some countries, random testing of self-contained luminaires is acceptable. In this case, this
requirement does not apply.
NOTE 2 All the other requirements of the test including timing and checking operation should be carried out
automatically.
Compliance is checked by confirming that the sequence of testing does not affect alternate
luminaires during the same test period. This is checked by inspection of the documentation of
the manufacturer.
6.3.2.3 Manual initiation of the test function
In case of a non-automatic initiation of the test, manual initiation of the test shall be
acceptable providing that there is a visible fault indication (as described in 7.2), or records of
previous tests which indicate that the discharge test has not been carried out within the
previous 12-month period.
NOTE 1 After the manual initiation, the operation of the test is automatic, including return to normal operation and
fault reporting.
NOTE 2 The purpose of these requirements is to ensure the safety of the premises when carrying out the duration
test.
Compliance is checked by inspection.
6.3.2.4 Automatic initiation of test function
Automatically initiated tests shall perform the tests in accordance with Clause 5. However, the
duration test shall be carried out within 52 weeks after commissioning. This requirement is
applicable only in combination with 6.3.2.2 for premises which may be occupied during the
test and the subsequent recharging period.
Random automatically-initiated rated duration tests shall be carried out within 52 weeks after
commissioning.
NOTE The operating instructions should draw attention to the possibility of adjacent luminaires being te
