ATEX ZONE 2
HAZARDOUS DUTY™
MOTORS
Background
• ATEX = “Atmosphere Explosible”
• European Union (EU) Directive 94/9/EC
• Mandatory (by law) for covered equipment
placed into service July 1, 2003
• Covers equipment with potential ignition
source, or components of equipment, such
as electric motors
Requirements for
certification
• “Notified Body” conformity assessment:
– EC Type examination (inspection of design)
– Production Quality Assurance
– Product Verification
– Internal Production Control
• Must have CE mark to confirm compliance
• ATEX directive based on CENELEC and
IEC standards
Area Classification
• Class I - Flammable gases, vapors & mists
– Zone 0 “Explosive continuously”
– Zone 1 “Explosive under normal conditions”
– Zone 2 “Explosive under abnormal conditions”
• Class II - Combustible dusts
– Zone 20 (same as Zone 0, for dusts vs gases)
– Zone 21 (same as Zone 1, for dusts vs gases)
– Zone 22 (same as Zone 2, for dusts vs gases)
Categories of Use
•
•
•
•
•
•
Categories M1 and M2 refer to mining
Categories 1G and 1D refer to Zone 0
Category 2G - Zone 1/Gas (non-mining)
Category 3G - Zone 2/Gas (non-mining)
Category 2D - Zone 21/Dust (non-mining)
Category 3D - Zone 22/Dust (non-mining)
Equipment Groups
• Group I (applicable to mining equipment)
• Group II (non-mining):
– Group IIA (propane-type gases)
• Gases covered under NFPA Group D
– Group IIB (ethylene gases)
• Gases covered under NFPA Group C
– Group IIC (acetylene and hydrogen)
• Gases covered under NFPA Groups A and B
Class II
Flammable gases,
liquids and mists
• Group IIA - Propane, acetone, ammonia,
benzine, butane, ethanol, gasoline,
hexane, methane, natural gas, naphtha
• Group IIB - Ethylene, ether, ethyl
• Group IIC - Acetylene, hydrogen,
butadiene, ethylene oxide, propylene
oxide, acrolein
Class II
Combustible Dusts*
• Group E - metal (N/A from Marathon)
• Group F - coal, coke, carbon black,
charcoal
• Group G - grain, flour, wood, plastic,
chemical
• Noted as “D” on nameplate marking
* ATEX does not define dust groups, as categorized for gases (eg.
IIA, IIB, IIC)
Class III
Ignitable Fibers & Flyings
• Class III locations
– Division 1: Easily ignitable fibers or materials
producing combustible flyings are handled,
manufactured or used.
– Division 2: Easily ignitable fibers are stored
or handled.
• No material groups defined
• Not available from Marathon Electric
Class I; Zone 0, 1 & 2
Protection Methods
• Zone 0 - not applicable to motors
• Zone 1:
– “Flameproof” (‘d’), IEC50018 compliant
– “Increased Safety” (‘e’), IEC50019 compliant
• Zone 2:
– “Non-Sparking” (‘nA’), IEC50021 compliant

ATEX markings
CE Mark asserts that equipment
meets all essential requirements of
the relevant European Directive. It is
often accompanied by the Notified
Body identification number. “CE”
may have originally stood for
“Conformite Europeenne” (European
Conformity).
0359
Ex Mark is the European Union (EU)
Explosive Atmosphere Symbol, and
is found on any equipment whose
end use or installation may be within
a hazardous location as determined
by the authority having jurisdiction.

Marketing Strategy
• Leverage existing relationships with NAbased OEMs that export equipment
• Emphasize lead-time advantage
• Target competitive weaknesses (not full line,
unknown entity in NA, questionable support,
exchange rate)
• Sell credibility (knowledgeable sales force, 3rd
Party Certification)
• Pull through with existing XP business
• Target Oil & Gas market, forecasted aboveaverage market performance
