#charge limit

… Standards bodies are already starting to revisit charge limits for hydrocarbons. For example, last year, the International Electrotechnical Commission published a long-awaited update of its global 60335-2-89:2019 standard for self-contained commercial refrigeration cabinets, raising the charge limit for A3 (flammable) refrigerants to 500 g from 150 g.

… The safety standards governing the use of A3 (flammable) and A2L (mildly flammable) refrigerants are an important consideration when making refrigeration equipment decisions. In 2019, the International Electrotechnical Commission (IEC) ruled to increase the charge limits of A3s and A2Ls from 150g to 500g and 1,200g, respectively, for commercial refrigerators and freezers.

… Just recently the International Electrotechnical Commission (IEC) increased the charge limit for A3 (flammable) refrigerants from 150g to 500g and increased the charge limit for A2 and A2L (low flammable) refrigerants from 150g to 1,200g in self-contained commercial refrigeration cabinets.

In the wake of the International Electrotechnical Commission’s recent approval of an increase in the charge limit for hydrocarbons to 500 g from 150 g, equipment manufacturers are assessing their product portfolio in anticipation of regional adoption of the higher hydrocarbon charge sizes. Some are already prepared, while others will be making updates.

In May, the International Electrotechnical Commission (IEC) approved an increase of the charge limit of hydrocarbons in self-contained commercial display cases to 500 g (17.6 oz) from 150 g (5.3 oz) under its IEC 60335-2-89 standard. After the new charge limit is adopted by regional standard bodies, will the move boost the prospects for hydrocarbons in commercial cases throughout the world?
