For long-term storage of frozen foods (up to 2–3 months), domestic freezers run at −18 °C (0 °F); in the UK this is a 3‐star rated deep freeze. A freezing compartment of a refrigerator (for short-term storage of frozen foods) is between −11 °C (12 °F), 2‐star rated, for storage up to 4 weeks; and −4 °C (25 °F), 1‐star rated, for storage up to a week. See also date marking.
A 3‐star rated deep freeze with a snowflake symbol is one that is suitable for freezing foods, as opposed to storing ready-frozen food; it has a higher cooling capacity than a simple deep freeze storage cabinet.
