Scope:

This part of IEC 60079 specifies the requirements for the design, construction, testing and marking of Ex Equipment and Ex Components with type of protection liquid immersion o intended for use in explosive gas atmospheres. 

Ex Equipment and Ex Components of type of protection liquid immersion o are either: 
 

  • Level of Protection ob (EPL Mb or Gb) 
  • Level of Protection oc (EPL Gc) 


For Level of Protection ob, this standard applies where the rated voltage does not exceed 11 kV r.m.s. a.c. or d.c. 

For Level of Protection oc, this standard applies where the rated voltage does not exceed 15 kV r.m.s. a.c. or d.c. 

NOTE Requirements for higher voltages are under consideration. 

This Standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. 

Project need:

To maintain alignment with international requirements (new amendment of adoption). This proposed new amendment is being developed at the request of CSA’s Integrated Committee on Hazardous Location Products (ICHL). It will provide the industry with the latest available international requirements
