IEC approves new A3 standard
LEFT: The new standard will be published 24 June, 2022.
A NEW INTERNATIONAL STANDARD WAS APPROVED LAST WEEK WHICH ALLOWS FLAMMABLE A3 REFRIGERANTS SUCH AS PROPANE (R290) IN DOMESTIC AIR CONDITIONERS, HEAT PUMPS AND DEHUMIDIFIERS.
AFTER 18 MONTHS of revi- sions the standard was finally approved by the International Electrotechnical Commission (IEC).
Officially designated IEC 60335-2-40, the new standard allows higher charge limits for hydro-
carbons such as R290 in residential applications. The revised safety standard allows for using a larger charge of flammable refrigerants (up to 988g of R290 in a standard split air-con system) in new equipment designed according to certain additional safety requirements to ensure the same high level of safety as equipment using
non-flammable refrigerants.
The new standard is expected to be published
24 June. Countries will then need to swiftly adopt the revisions into their national legislation.
Convenor of the IEC working group that shep- herded the standard through its revisions was Asbjørn Vonsild.
“The new Edition of IEC 60335-2-40 will ena- ble R-290 [propane] to be used in many A/C and heat-pump systems which were previously blocked from using this refrigerant by the out- dated version,” he said.
The Environmental Investigation Agency (EIA) welcomed the revisions stating the new standard will potentially represent massive cuts in the emission of climate harming refrig- erant gases.
“Hydrocarbons are cost-effective, efficient cli- mate-friendly refrigerants, but due to their flam- mability they have been restricted to very small charge sizes in cooling equipment,” the EIA said in a statement.
EIA climate campaign leader Clare Perry said the agency had been urging governments and in- dustry to address this issue for many years.
“EIA is delighted to see this critical milestone reached on the pathway to net-zero and clean sustainable cooling,” Perry said.
“This will enable a thousand-fold reduction in direct climate emissions compared with systems using R410A.”
