globally. It complements ABB’s existing ATEX and
other approvals.
Benefits of IECEx System for end users
A significant advantage of IECEx is that vendor
certificates are available for inspection on the
IECEx website. End users can therefore confirm the
validity of IECEx certificates at any time - which is
not possible with ATEX, for example. This increases
end user confidence that the motor vendor will be
committed to maintaining the necessary quality
systems.
Under the quality based IECEx certification ap-
proach the interpretation of the standard is shared
throughout the 30 participating countries and in-
dividual interpretations by Notified Bodies are not
allowed. Another advantage of IECEx is that the
Certificate of Conformity also covers EPL (equip-
ment protection level) “c”, see table on next page.
Which ABB motors and generators are IECEx
certified?
All motors listed in this catalogue are IECEx certi-
fied, except motor types M3HP and M3AA in frame
sizes 71 to 80.
Compliance on basis of recently updated stan-
dards
In complying with the ATEX 95 directives, ABB fol-
lows the requirements of recently updated IEC and
EN standards. Otherwise ABB follows the require-
ments of the IEC standards shown in the relevant
certificates.
Main standards for explosive atmospheres:
IEC/EN 60079-0 Equipment - General requirements
IEC/EN 60079-1 Equipment protection by flameproof
enclosures “d”
IEC/EN 60079-7 Equipment protection by increased
safety “e”
EC/EN 60079-15
*
Equipment protection by type of
protection “n”
IEC/EN 60079-31 Equipment dust ignition protection by
enclosure “t”
IEC/EN 60079-14 Electrical installations design, selection
and erection
IEC/EN 60079-17 Electrical installations inspections and
maintenance
IEC/EN 60079-19 Equipment repair, overhaul and
reclamation
IEC 60050-426 Equipment for explosive atmospheres
IEC/EN 60079-10 Classification of hazardous areas (gas
areas)
IEC 60079-10-1 Classification of areas - Explosive gas
atmospheres
IEC 60079-10-2 Classification of areas - Combustible dust
atmospheres
* Moved to IEC/EN 60079-7 in 2015 revision.
verification that the equipment in question is in
compliance with the relevant IEC standards. Once
formally issued by the ExCB, both the ExTR and
QAR are registered on the IECEx Internet site. This
provides verification that an ExTR and QAR exist
for the product and manufacturer.
How do I know if a motor is IECEx certified?
IECEx certified motors show the certification
number on their rating plate, for example: “IECEx
LCI 05.0008”. In this case “LCI” indicates that the
IECEx certificate was issued by LCIE, an IECEx ap-
proved Certification Body in France.
In addition, IECEx certificates are issued in elec-
tronic form and are publicly available on the IECEx
website. They can therefore be viewed and printed
by anyone with access to the Internet. See “Certifi-
cates & Licences” at www.iecex.com.
IECEx certification is particularly useful in certain
markets. In Australia, New Zealand, and Singapore,
for example, IECEx certificates are accepted, but
not all IEC certificates are accepted. Certain other
countries, including Russia, China and Korea, are
prepared to accept ExTRs as a basis for their own
national certificates. There are also many countries
that are willing to accept products covered by cur-
rent IECEx certificates, even though the countries
in question are not members of the IECEx Manage-
ment Framework.
IECEx Conformity Mark License
The IECEx Conformity Mark System was intro-
duced in 2008. IECEx Conformity Mark Licenses are
issued by approved Certification Bodies in IECEx
participating countries.
The IECEx Conformity Mark shows that a product
has been granted an IECEx Certificate of Confor-
mity. IECEx Certification confirms that the product
has the appropriate protection for use in explosive
atmospheres and that it has been manufactured
under systems subject to ongoing surveillance
by Certification Bodies. It is recognized in all the
countries participating in the IECEx System, and it
also means that the product can be supplied to the
market without the need for additional tests.
ABB has been granted IECEx Certification for a
wide range of low and high voltage motors, and
these can therefore display the IECEx Conformity
Mark. The hazardous area protection types pro-
vided by these motors include
– Flameproof Ex d, Ex de
– Non-sparking Ex nA
– Increased safety Ex ec
– Dust protection Ex t
The IECEx Conformity Mark License will consider-
ably enhance ABB’s ability to market its products
