Safety in installations for electroheating and electromagnetic processing - Part 12: Particular requirements for infrared electroheating

IEC 60519-12:2016 specifies safety requirements for industrial electroheating equipment and installations in which infrared radiation – usually generated by infrared emitters – is significantly dominating over heat convection or heat conduction as means of energy transfer to the workload. A further limitation of the scope is that the infrared emitters have a maximum spectral emission at longer wavelengths than 780 nm in air or vacuum, and are emitting wideband continuous spectra such as by thermal radiation or high pressure arcs. This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a. the structure has been redrafted according to IEC 60519-1:2015;
b. terms/definitions, normative references and bibliography have been updated and completed;
c. all requirements and content from IEC 60519-12:2013 that have been included in IEC 60519-1:2015 have been removed to avoid any duplication.

Sécurité dans les installations destinées au traitement électrothermique et électromagnétique - Partie 12: Exigences particulières pour chauffage électrique par rayonnement infrarouge

L’IEC 60519-12:2016 spécifie les exigences de sécurité concernant les équipements et installations électrothermiques industriels avec lesquels le rayonnement infrarouge, produit habituellement par des émetteurs de rayonnement infrarouge, prédomine véritablement sur la convection ou la conduction thermique comme moyen de transfert d'énergie à la charge de travail. Une limite supplémentaire du domaine d'application se traduit par le fait que les émetteurs de rayonnement infrarouge ont une émission spectrale maximale à des longueurs d’onde plus grandes que 780 nm dans l'air ou le vide, et émettent des spectres continus à large bande tels que ceux émis par un rayonnement thermique ou des arcs à haute pression. Cette deuxième édition annule et remplace la première édition parue en 2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a. la structure du présent document a été alignée sur celle de l’IEC 60519-1:2015;
b. les termes/définitions, les références normatives ainsi que la bibliographie ont été mis à jour et complétés;
c. toutes les exigences et le contenu de l’IEC 60519-12:2013 repris dans l’IEC 60519-1:2015 ont été supprimés pour éviter les répétitions.

INTRODUCTION
The scope of this standard covers a broad range of types and designs of infrared equipment
which are used for many different purposes. This standard is intended to cover all industrial
infrared equipment types, with some few exceptions provided in Clause 1.
Many other types of electroheating equipment emit infrared radiation of hazardous levels,
therefore IEC 60519-1:2015 provides all general requirements addressing optical radiation
and this document provides specific considerations for infrared equipment and helpful
methods.
With reference to IEC 60519-2:2006 it has been agreed in TC 27 that this standard covers all
kinds of infrared emission hazards of industrial electroheating installations and provisions not
given in IEC 60519-1:2015.
The discussion of infrared radiation assessment has become quite detailed in this standard,
as for the industry there is not any single useful source available for simple, versatile, easy to
use and cost effective measurement methods.
The other principles for covering the risks caused by infrared radiation were:
• the manufacturer usually does not employ an expert in optical radiation measurement or
has access to an optical laboratory with all the necessary equipment needed for elaborate
measurements;
• operating staff with limited experience in radiation measurement is usually responsible for
the task of performing the necessary measurements and will appreciate a simple and easy
to follow guide;
• the scope of IEC 62471:2006 is limited to lamps but is applicable for other light sources.
Therefore, core aspects were adapted from that standard and if possible simplified for this
document.
• figures illustrating the classes defined in IEC 62471:2006 and listed in IEC 60519-1:2015
are included;
• relevant documents of American National Standard Institute/Illuminating Engineering
Society of North America, the ANSI/IESNA RP 27 series, are based on the ICNIRP
recommendations as well. They provide no extra or contradictory material with regard to
this standard and its references.

SAFETY IN INSTALLATIONS FOR ELECTROHEATING
AND ELECTROMAGNETIC PROCESSING –

Part 12: Particular requirements for infrared electroheating

1 Scope and object
1.1 Scope
This clause of Part 1 is replaced by the following.
Replacement:
This part of IEC 60519 specifies safety requirements for industrial electroheating equipment
and installations in which infrared radiation – usually generated by infrared emitters – is
significantly dominating over heat convection or heat conduction as means of energy transfer
to the workload. A further limitation of the scope is that the infrared emitters have a maximum
spectral emission at longer wavelengths than 780 nm in air or vacuum, and are emitting
wideband continuous spectra such as by thermal radiation or high pressure arcs.
IEC 60519-1:2015 defines infrared as radiation within the frequency range between 400 THz
and 300 GHz. This corresponds to a wavelength range between 780 nm and 10 µm in
vacuum. Industrial infrared heating commonly uses thermal infrared sources with rated
temperatures between 500 °C and 3 000 °C; the emitted radiation from these sources
dominates in the wavelength range between 780 nm and 10 µm.
Since substantial emission of thermal emitters can extend either to wavelengths below
780 nm or above 3 000 nm, the safety aspects of emitted visible light and emission at
wavelengths longer than 3 000 nm are also considered in this document.
This standard is not applicable to:
• infrared installations with lasers or light-emitting diodes (LEDs) as main sources – they are
covered by IEC 62471:2006 and IEC 60825-1:2014;
• appliances for use by the general public;
• appliances for laboratory use – they are covered by IEC 61010-1:2010;
• electroheating installations where resistance heated bare wires, tubes or bars are used as
heating elements, and infrared radiation is not a dominant side effect of the intended use,
covered by IEC 60519-2:2006;
• infrared heating equipment with a nominal combined electrical power of the infrared
emitters of less than 250 W;
• handheld infrared equipment.
Industrial infrared electroheating equipment under the scope of this standard typically uses
the Joule effect for the conversion of electric energy into infrared radiation by one or several
sources. Radiation is then emitted from one or several elements onto the material to be
treated. Such infrared heating elements are in particular:
• thermal infrared emitters in the form of tubular, plate-like or otherwise shaped ceramics
with a resistive element inside;
• infrared quartz glass tube or halogen lamp emitters with a hot filament as a source;

– 8 – IEC 60519-12:2016 © IEC 2016
• non insulated elements made from molybdenum disilicide, silicon carbide, graphite, iron-
chromium-aluminium alloys, refractory metals or comparable materials;
• wide-spectrum arc lamps.

This clause of Part 1 is applicable with the following addition:
Addition:
9.101 Protective measures against infrared radiation
9.101.1 General aspects
Technical measures to reduce exposure to infrared radiation include:
• The installation of suitable shields to reduce or avoid the emission of visible or infrared
radiation from the equipment. This includes sufficient infrared enclosure (i.e. housing) of
the infrared equipment. Shields and housing can become dangerously hot to the touch, if
no sufficient measures are taken.
• Positioning of the radiation source so that no or only reduced radiation is directed towards
persons.
• Suitable filters reduce the emission of infrared radiation emitted from the infrared
electroheating equipment. Absorbing filters can become dangerously hot surfaces to
touch.
Organisational measures are suitable during commissioning or maintenance work only, they
include:
• Limiting access by physical means. Installation of infrared barriers to hinder access to
areas with high radiation.
• Reducing exposure time of persons.
• Placement of suitable warning signs.
• Instruction of the operating staff in the hazards of infrared radiation and in the use of
suitable protective measures.
• Use of personal protective measures and equipment.

– 12 – IEC 60519-12:2016 © IEC 2016
• Use of suitable clothing and gloves for the protection of the skin.
• Use of suitable glasses and filters for the protection of the eyes. Filters shall reduce the
dangerous level of emission, without impairing the needed visual information.
NOTE Measures to reduce exposure include avoidance of exposure through the use of another heating method
(see ISO 12100:2010). As most other heating methods generate infrared radiation that reach similar infrared
intensity as infrared electroheating itself, avoidance is usually not possible through this measure.
9.101.2 Access points in the infrared enclosure
As part of the routine maintenance or setting of an installation, it can be necessary to
measure the intensity or intensity distribution inside the infrared equipment, or to inspect the
workload visually, or to inspect the inside of the equipment visually. If there is a need for
access to the inside of the equipment or to the infrared radiation inside of the equipment,
access points in the infrared enclosure shall be included during the design stage. The
construction of access points shall not create emission of radiation above the level specified
in the design targets.
To reduce emission through access points, the following measures shall be considered:
• they can be sealed by a door, which shall be able to open only with a tool, or
• they can have a window that shall include an infrared filter reducing the emission from that
access point to a safe level.
9.101.3 Design of shields
Wherever possible, the infrared radiation shall be enclosed to prevent inadvertent access to
levels of radiation above the design target level. The design of enclosure and shields depends
on how these components are to be used including whether they will be removable or fixed
and if they will require maintenance.
The equipment and the materials used for the attenuation of radiation shall withstand all
effects of the environmental and operating conditions expected at intended use as well as
during fault conditions. These factors include the climate, chemical and biological factors, the
atmosphere near and inside the equipment (dust, vapours, and flammability), effects from
periodic cleaning, and mechanical factors like vibration.
When applicable, the following requirements for the infrared enclosure and shields shall be
fulfilled:
• the infrared emitter(s) shall be positioned so that the enclosure cannot be damaged by
normal operation or any single fault condition which would lead to a change in the
emission characteristics. If necessary, further mechanical protection shall be provided in
order to achieve this;
• the emitter(s) shall be securely mounted. Normal operation or single fault conditions shall
not cause them to dislodge;
• if the opening of a shield, a barrier or part of the enclosure gives an automatic "stop"
command, the closing of the respective shield, barrier or enclosure shall not reactivate the
emission without a further operation;
• the design of the enclosure and the mount(s) shall facilitate infrared emitter replacement
without significant exposure to the operator;
• any further mechanical protection shall not increase the radiation emission hazard or other
hazards by virtue of its presence or location;
• all detectors and indicators, the power source, all shields, shutters, and interlocks shall
operate in a "fail to safety" mode.
9.101.4 Removing of shields
If the design target levels of radiation exposure will be exceeded when shields are removed

• the emitters shall be automatically switched off, or
• mechanical shutters or other means used to restrict the emissions to the design target
levels shall hinder emission.
If this is not possible, then the shield shall
• have fastenings which require a tool to release them, and
• suitable permanent warnings signs shall be affixed to them.
If shields or parts of them are designed to be removed for maintenance, the arrangement of
fasteners shall ensure correct replacement.

18.101 Considerations and methods for measurements of infrared radiation
The measurement of optical radiation for the purpose of computing photo-biological radiation
values poses significant challenges. Spectral irradiance or radiance measurements using a
monochromator or spectrometer are difficult to make in the infrared due to a lack of simple or
cost effective equipment made for industrial applications.
As no weighting function is defined at wavelengths greater than 1 400 nm, broadband
measurements are suitable in evaluating those infrared hazard conditions that have no
weighting function to consider. If the cumbersome measurement of spectrally resolved data
and application of weight functions is not undertaken, either the maximum value of the weight
function may be used over the complete wavelength range, or the measurement method of
Annex BB. This measurement method does not need spectrally resolved measurements in the
infrared, but still takes weight functions into account.
All hazard values shall be reported
• at a distance of 100 mm from the equipment, if the equipment is freely accessible, or
• if access is restricted, at all exposed and accessible positions.
The measurement equipment shall be oriented, to capture the highest signal.
NOTE Visually black surfaces can be reflective to infrared radiation.
The infrared equipment shall be operated under conditions that generate the maximum
radiation emission from the equipment within normal operating conditions; single fault
conditions being excluded. If different conditions during normal operation for different phases
of the life cycle ensue, all of these need to be tested if possible:
• in case of equipment that is operated with or without workload, both cases shall be
considered;
• in case of equipment that runs cyclic, all phases of a cycle shall be considered;
• in case of equipment with doors opening and closing during processing, open and closed
states shall be considered.
For a simplified measurement method that uses a broad band detector as the sole
measurement device, use Annex BB.
If Annex BB of this standard is used as measurement method, it shall supplement 5.2 and 5.3
of IEC 62471:2006.

(informative)
Procedure for reducing risk from infrared radiation
If the equipment can cause hazardous emission of infrared radiation during some stages of its
life cycle, the procedure given in Table AA.1 can be used for risk assessment and risk
reduction.
Some steps of the procedure for assessing and reducing radiation exposure of persons from
the equipment through technical means depend on the product being a unique installation
made to order or being manufactured repetitively. Repetitively manufactured equipment and
made to order equipment usually differ in their respective design process. Manufacturers and
users usually agree jointly on the design only in the design process for made to order
equipment. Therefore, in this case responsibility for design decisions can be shared between
the manufacturer and user.
If emission occurs by intent only during commissioning or maintenance phase and
organisational means are sufficient to prevent harm, the procedure given in Table AA.1 is not
necessary, but classification and documentation follow this standard.
