To complicate matters, this needs to be converted into a tonnes of CO2 equivalent, the result of which will tell you the required F-gas leak test frequency. To do this, you must divide the mass of F-gas by 1,000 to convert it to tonnes, then multiply this by the gas’ GWP (you can find more information and example calculations here).
Using R32 as an example, if your system contained:
7.4kg - this is equivalent to 5 to <50 tonnes of CO2. Your system would need to be leak tested every year (once every two years if a fixed leak detector is installed)
74.1kg - this is equivalent to 50 to <500 tonnes of CO2. Your system would need to be leak tested every six months (once every year if a fixed leak detector is installed)
If your system contained >500 tonnes of CO2 equivalent, you must have a fixed leak detection system in place. You must also undertake manual testing every six months.
Who Can Carry Out F-Gas Leak Testing?
F-gas leak tests can only be carried out by qualified engineers. These engineers must have a category 1 certificate in working on equipment containing F-gas from the likes of BESA, LCL Awards or City and Guilds.
They must also work for a company that is certified to install, repair, maintain and decommission stationary equipment containing F-gas. This certification can be obtained from Bureau Veritas UK, F-Gas Register or REFCOM. If work is undertaken by anyone not qualified to do so, your temperature control system will not be legal and you may receive a hefty fine.
At Loughborough Air Conditioning, we pride ourselves on going beyond basic requirements. In addition to our F-gas certificate from REFCOM we’re also members of REFCOM Elite - a voluntary scheme that promotes best practice in refrigerant management - and all our engineers are registered under the ACRIB F-Gas Refrigeration SKILLCard scheme.
We’ve been helping businesses across the East Midlands stay F-gas compliant for over 20 years and offer regular F-gas leak testing as part of our planned preventative maintenance packages.
