R290 Charge Limit Increase - What's Next?

Last year, the International Electrotechnical Commission (IEC) 60336-2-89 standard was updated to increase the charge limit for hydrocarbons, including R290, to 500g at the international level. Since then, a CANENA technical harmonization committee has been working to adapt the IEC standard in the US, where the charge limit is still 150g.
