Generators vs. Pressure Equipment Regulations (PER)

  • The generator engine is excluded from the PER but not the combustion system part thereof.
  • The internal combustion engine and all its mechanical parts is excluded from the PER
  • The complete gas supply and gas fueling system with its safety and control system is regulated by the PER and will require a Certificate of Conformity (CoC).  
  • Stationery gas engines will require a CoC. The source type and applicable safety standards will determine the type of CoC to be used
    • The use of any hydrocarbon gas to fuel an internal combustion engine including a turbine is regulated by the PER and the fueling supply and delivery system is seen as a gas system with all components from safety devices to control sensors and systems.
    • The fuel source would determine which standard will be used. i.e. SANS 10087-6 and SANS 20067 for Liquefied Petroleum Gas;  SANS 20110 and SANS 15500 parts 1-20 for Natural Gas
    • Depending on the fuel source and consumption of the engine would determine what additional standards would be required being either SANS 329, SANS 347, SANS 827  or SANS 087-3.
  • The use of gas generators were before 2009 excluded from requiring a CoC . This has changed and any application of hydrocarbon gas used in internal combustion engine as per the PER requires a CoC.
  • Fuel sources could be from Liquefied Petroleum Gas, Natural Gas, Compressed Natural Gas, Liquefied Natural Gas, Syngas and Biogas. 
  • Applications could be industrial, commercial, automotive, stationary and special hybrids are included.
