Regulatory leak testing on refrigerants

Leak testing equipment conveying refrigerants.

Preventing leaks on refrigeration systems

Refrigeration system equipment (compressors, condensers, evaporators, etc.), air conditioning units, chillers, driers, heat pumps, refrigerators, etc. contain refrigerants such as R14, R23, R125, R134a, R152a, R227, R404A, R407C, R410A, R413A, R417A, R507, R508B, Isceon 59, Isceon 89, Forane 23, Forane FX 80, SF6, NH3, etc.

Seal installation issues or ageing will inevitably generate leaks.
Detecting and repairing leaks will ensure you are ISO 50001 compliant

  • by reducing product losses (reducing energy consumption)
  • by slowing the ageing of the facility.

Leak testing

Bureau Veritas conducts leak testing programmes. Our method consists of several steps:

  • Analysis of the facility
  • Verification of measuring equipment
  • Detection and measurement of leaks on all seals using our standardised analysers or Infra-Red cameras specially designed to detect refrigerants. The Orders of 7 May 2007 and 25 July 2016, as well as successive updates relating to certain refrigerants, specify that “the leak testing of refrigeration equipment shall be done by passing a manual detector over all points exhibiting a risk of leakage”
  • Application of a standard blue “Pass” sticker on equipment tested to be leaktight with expiry date
  • Application of a standard red “Fail” sticker on leaking equipment
  • Completion of regulatory work reports (CERFA)
  • Production of mission report
  • Conservation of logs for long-term monitoring of facilities

The Order of 25 July 2016 defines the frequency of these leak tests:
