HC charge limit may stop at 300 g in U.S.

…The International Electrotechnical Commission (IEC) is expected to start its final vote on whether to increase the charge limit to 500 g for A3 (flammable) refrigerants in mid-March and conclude in mid-May, according to Marek Zgliczynski, Embraco’s director of research and development, who chairs the IEC SC61C subcommittee. If passed, the standard would be published in August. Then countries and regions could use it as a reference to enact binding standards. However, in the U.S., it is widely rumored that the standards bodies that would approve a charge limit increase for hydrocarbons – ASHRAE and UL – may want to limit the increase to 300 g, not 500 g.
