Overview

IEC 62493:2009 is an international standard developed by the International Electrotechnical Commission (IEC) focusing on the assessment of lighting equipment related to human exposure to electromagnetic fields (EMF). This standard provides a comprehensive evaluation framework for measuring electromagnetic fields generated by lighting equipment, ensuring safety for human health by adhering to specified exposure limits.

The standard covers assessment methods for induced current density within frequencies ranging from 20 kHz to 10 MHz and specific absorption rate (SAR) for frequencies between 100 kHz and 300 MHz around lighting devices. It is important to note that IEC 62493:2009 does not apply to built-in components such as electronic control gear within luminaires.

Key Topics

• Scope and Application: Focuses on EMF exposure assessment near lighting equipment, excluding built-in electronic components.
• Exposure Metrics:
  • Induced current density (20 kHz to 10 MHz)
  • Specific Absorption Rate (SAR) (100 kHz to 300 MHz)
• Measurement Procedures:
  • Standardized operating conditions and measurement distances
  • Use of specified test heads and instrumentation setups
• Limits and Compliance:
  • Based on international safety limits for the general public as defined by ICNIRP (International Commission on Non-Ionizing Radiation Protection) and IEEE exposure standards (IEEE C95.1, IEEE C95.6)
  • Emphasizes compliance with basic exposure restrictions rather than maximum permissible or reference levels
• Measurement Uncertainty and Instrumentation: Ensures reliable and reproducible results with clear guidelines on instrumentation calibration and uncertainty management.
• Test Report Requirements: Detailed documentation of test conditions, results, and compliance evaluation.

Applications

IEC 62493:2009 is critical for manufacturers, testing laboratories, and regulatory bodies working with lighting technologies where EMF exposure is a concern. Common practical applications include:

• Safety certification of lighting equipment such as fluorescent lamps, LED lighting, and other luminaires to comply with human exposure limits.
• Product development and evaluation to identify and mitigate electromagnetic emission risks during the design phase.
• Regulatory compliance for market access where national or regional legislation references IEC 62493 for EMF safety.
• Risk assessment in environments where lighting is installed close to personnel or in public spaces, ensuring EMF levels remain within accepted health standards.
• Quality assurance testing for consistency in production batches of lighting equipment.

Related Standards

IEC 62493:2009 interacts with several other standards and guidelines for EMF exposure and electrical equipment safety:

• ICNIRP Guidelines for Limiting Exposure to Time-Varying Electric and Magnetic Fields – Provides the basis for exposure limits referenced in IEC 62493.
• IEEE Standard C95.1 and C95.6 – Sets basic restrictions related to EMF exposure, complementary to ICNIRP.
• CISPR 15 – Specifies limits and methods related to radio disturbance characteristics of electrical lighting equipment.
• IEC 60598 series – Covers general requirements and tests for luminaires, which may complement the assessment of built-in components not covered by IEC 62493.
• ISO/IEC Directives, Part 2 – Governs the form and preparation of IEC standards including IEC 62493.

INTRODUCTION
This International Standard establishes a suitable evaluation method for determining the
electromagnetic fields in the space around the equipment mentioned in the scope, and
defines standardized operating conditions and measurement distances.
This standard is designed to assess, by measurements and/or calculations, electromagnetic
(EM) fields and their potential effect on the human body by reference to exposure levels of the
)
general public given by ICNIRP:1998 [1] , IEEE C95.1:2005 and IEEE C95.6:2002[2]. The
exposure levels with which to comply are basic restrictions (both ICNIRP- and IEEE-based).
NOTE 1 Maximum permissible exposure levels (IEEE-based) or reference levels (ICNRIP-based) are not used.
Based on the lighting equipment operating properties, the frequency range of the applicable
basic restrictions can be limited as follows:
• induced current density between 20 kHz to 10 MHz;
• specific absorption rate (SAR) between 100 kHz to 300 MHz;
• power density is outside the scope.
NOTE 2 Operating frequencies of lighting equipment are higher than 20 kHz to avoid audible noise and infrared
interference. Frequency contributions above 300 MHz can be neglected.
This standard is not meant to supplant definitions and procedures specified in exposure
standards, but it is aimed at supplementing the procedure already specified for compliance
with exposure.
The exposure limits given in Annex C (informative) are for information only, do not comprise an
exhaustive list and are valid only in certain regions of the world. It is the responsibility of users of
this standard to ensure that they use the current version of the limit values specified by the
applicable national authorities.

If the uncertainty calculated with the instrumentation actually used for the test (U ) is less or
lab
equal than the uncertainty given in 5.5 (U ) then:
basic
– compliance is deemed if the measurement result does not exceed the applicable limit.
– non-compliance is deemed to occur if the measurement result exceeds the applicable
limit.
If the uncertainty calculated with the instrumentation used for the test (U ) is higher than the
lab
uncertainty given in 5.5 (U ) then:
basic
– compliance is deemed to occur if the measurement result, increased by (U – U ),
lab basic
does not exceed the applicable limit.
– non-compliance is deemed to occur if the measurement result, increased by (U – U ),
lab basic
exceeds the applicable limit.
6 Measurement procedure
6.1 General
The assessment method is based on basic restrictions given in both ICNIRP 1998 and
IEEE C95.1 2005. The measurement procedure used simulates the current density in a
person near lighting equipment. The measurements are carried out under the conditions
specified in Table A.1 of Annex A.
6.2 Operating conditions
6.2.1 Operating conditions for general lighting equipment
Measurements on the lighting equipment shall be carried out in operating conditions as
specified by the manufacturer.
In the case of lighting equipment where it is possible to interchange between lamps of
different rated wattage, it is only necessary to measure the lighting equipment in combination
with the lamp that has the highest nominal lamp voltage.
Prior to measurement, the lamp(s) shall be operated until stabilisation has been reached.
Unless otherwise stated by the manufacturer, the following stabilisation times shall be
observed:
– 15 min. for fluorescent lamps;
– 30 min. for other discharge lamps.
All measurements have to be done with 100 h aged lamps.
6.2.2 Operating conditions for specific lighting equipment
Multiple lamp lighting equipment: When the lighting equipment incorporates more than one
lamp, all lamps shall be operated simultaneously.
Self-contained emergency lighting equipments: If the appliance can be connected and be
operated from the mains it shall be tested in this mode of operation. No tests are required in
the battery-operating mode.
Lighting equipment capable of light regulation shall be measured at both the maximum and
minimum limit of light regulation.

– 14 – 62493 © IEC:2009
Measurements shall be carried out within ± 2 % of the rated supply voltage. In the case of a
voltage range, measurement shall be carried out within ± 2 % of minimum and maximum
nominal supply voltage of that range.
6.3 Measurement distance
Lighting equipment is evaluated in accordance with the measurement distance given in
Table A.1 of Annex A unless otherwise specified by the manufacturer. The external surface of
the test-head is taken as the reference point when determining the measurement distance.
Tolerances of the measurement distances are ± 5 %.
6.4 Measurement set-up
The measurement set-up is given in Figure 3.

Figure 3 – Measurement set-up
If the lighting equipment is provided with an earthing terminal, the lighting equipment shall be
connected by means of an earth conductor contained in the power cable to the lighting
equipment.
During the tests no conductive plane or object or human being should be closer to the lighting
equipment than 0,8 m.
The height of the insulated support is minimum 0,8 m. The conducting sphere is connected to
the protection network via an ordinary wire of length 30 cm ± 3 cm. The protection network is
then connected to the EMI receiver, or spectrum analyser, by a 50 Ω coaxial cable having a
maximum cable loss of 0,2 dB and a d.c. resistance of ≤ 10 Ω.

6.4.1 Measurement set-up for specific lighting equipment
6.4.1.1 Self-ballasted lamps
These lamps shall be inserted directly into a lamp holder, which is mounted on a piece of
insulating material. The measurement test-head is positioned at the measurement distance as
specified in Table A.1 from the end of the lamp.
6.4.1.2 Independent electronic control gear
Independent electronic control gear shall be mounted on a piece of insulating material
together with a suitable lamp of the maximum permitted power. The load cable(s) between the
control gear and the lighting equipment shall be 0,8 m with a relative tolerance of 20 %
unless otherwise specified by the manufacturer. The configuration of control gear, lighting
equipment and cable(s) shall be measured in accordance with Figure B.2e.
6.5 Location of measurement test-head
The measurement locations shall be selected in accordance with the following criteria.
Measurements shall only be performed in a direction consistent with that of the likely
exposure of the general public during normal use.
In the case of lighting equipments incorporating double capped fluorescent lamps greater than
30 cm, the test-head is positioned as shown in Figure B.2a. The measurement procedure is
repeated for both ends of the lamp, and in the case of multiple-lamp lighting equipment each
lamp is measured in-turn.
In the case of lighting equipment for other lamps, the test-head is positioned at the
appropriate measurement distance as specified in Table A.1, central to the point of intended
illumination.
For those lighting equipment where a central point of illumination cannot be determined, or
where the direction of illumination is not in the direction of the general public during normal
use, for example an up light, a measurement point is selected at the appropriate test distance
from the lighting equipment around its perimeter. More than one measurement point maybe
selected to confirm the performance of the lighting equipment.
Figures B.2a to B2.f in Annex B give examples of the location of the measurement point(s) for
typical lighting equipment.
6.6 Calculation of the results
The measurement results are calculated in accordance with Annex E.
