F-Gas compliance

F-Gas compliance Leakage inspection

  • Leakage inspection

    Systems shall be checked for leakage dependent on CO2 equivalent, the calculation to work this out is as follows:

    CO2e = GWP x charge weight per circuit /1000
    GWP for R22=1700
    GWP for R407c=1774
    GWP for R410a=2088
    GWP for R134a=1430

    Leak Testing
    - Annual (A) on equipment containing 5 tonnes of CO2 equivalent
    - 6 monthly (6M) on equipment containing 50 tonnes of CO2 equivalent
    - Quarterly on equipment containing 500 tonnes of CO2 equivalent


    Hermetically sealed systems, which are labelled as such and contain less than 6kg, are exempt.

    Operators of equipment containing 300kg or more must install an automatic leakage detection system. These must be checked at least once every twelve months to ensure they are functioning properly.

    Checked for leakage means that the system is systematically checked for leakage using direct or indirect methods, focusing on those parts of the system most likely to leak. The cause of any leak will need to be recorded in the log book.

    A detailed definition of what constitutes a leak check will be part of legislation attached to F-Gas.

  • Refrigerant type

  • If other make a note here

  • Amount of refrigerant (kg)/circuit
  • Refrigerant (kg)

  • Leak test carried

  • Leak test result<br>Safe = No leak found At Risk = Leak present, make notes and take pictures

  • Refrigerant leak detection installed

  • Refrigerant leak detection operating correctly
