Webinar on possible updates to flammable charge limits
“Cool & Safe: Climate-friendly cooling is just one step away” is a free one-hour webinar on September 30 about the proposed update to the international standard for the use of flammable refrigerants in room air conditioners. It is organised by Environmental Action Germany and independent consulting firm HEAT, in cooperation with German development agency GIZ […]

Flammable charge limits on the move again
Charge sizes for flammable refrigerants in HVAC&R equipment are changing with a proposal to raise international limits for room air conditioners, and the adoption of a new standard in Australia for refrigeration appliances. An International Electrotechnical Commission (IEC) working group has released a proposal to update safety standard IEC 60335-2-40. This would allow larger amounts […]

Road to raising flammable charge limits
Life Front has released a new report with recommendations on how to safely raise the charge limits for flammable refrigerants in refrigeration, air conditioning, and heat pump (RACHP) applications. The EU-funded project aims to remove implementation barriers posed by legacy charge-limit standards. The report comes after the International Electrotechnical Commission (IEC) paved the way for […]

IEC reverses vote on flammable charge limit
The path to higher charge limits for flammable refrigerants looks to be open again, after the International Electrotechnical Commission (IEC) revised last month’s surprise no vote. At this stage it is not clear why or how the vote was reversed, although as the original count only failed by 0.7 per cent, it’s possible that a […]

IEC rejects rise in flammable charge limit
The International Electrotechnical Commission (IEC) committee responsible for IEC Standard 60335-2-89 has narrowly voted down a draft international standard that would have raised the allowable charge of flammable refrigerants in certain appliances. The vote comes after a five-year effort to raise the charge limit of flammable refrigerants such as propane and isobutane in some commercial […]

Charge limit increase imminent
The International Electrotechnical Commission (IEC) has taken the next step towards increasing the charge limit of A3 refrigerants in commercial refrigeration equipment. As reported earlier this year, the change would increase the limit on A3 (flammable) refrigerants such as propane in commercial refrigeration equipment from 150g to 500g. This would enable hydrocarbons to be used […]

Interim IEC vote approves increased HC charge limit
The International Electrotechnical Commission (IEC) has voted to increase the charge limits of flammable A3 hydrocarbon refrigerants, such as propane, in commercial refrigeration equipment. This is an interim vote, meaning that the change must still go through other steps before it is enacted as a global standard. If there are no obstacles that could happen […]
