HAZARDOUS DUTY™

MOTORS

background
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
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
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 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
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
Class IIFlammable 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
Class IICombustible 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 IIIIgnitable 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
Class I; Zone 0, 1 & 2Protection 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
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).

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.
