AS/NZS 60335.2.89:2020 PDF Download

For commercial refrigeration appliances and ice makers with an integrated or remote refrigerant unit or motor-compressor, the AS/NZS 60335.2.89:2020 standard outlines safety criteria. The standard includes service counters, blast chillers, blast freezers, and commercial ice makers among the many pieces of equipment it covers. It also includes refrigerated display and storage cabinets, refrigerated trolley cabinets, and service counters.

The standard intends to mitigate frequent risks connected to this equipment, such as those caused by R-744 and flammable refrigerants. Appliances that employ refrigerants with a toxicity classification of B or whose mass of flammable refrigerant exceeds the limits stated are exempt from this rule.

It is significant to note that this standard excludes construction and operation-related aspects that are covered by ISO standards. Additional national requirements established by health authorities, labor protection authorities, water supply authorities, and similar organizations may also apply to equipment used in automobiles, ships, or aircraft.

Additionally, there are specific exclusions from this standard, including equipment using flammable refrigerants in transcritical refrigeration systems, domestic refrigeration equipment, split systems with a refrigerant charge that exceeds a certain threshold, industrial refrigeration equipment, motor-compressors, commercial dispensing and vending equipment, commercial ice-cream equipment, cold temperature rooms, and multiple refrigerated chambers with a remote motor-compressor.
