Whilst this bespoke test description does not fall under our NATA ISO/IEC17025 accreditation, SuperTest uses our established quality framework to ensure quality, impartiality, traceability, comparability, and validity in all our outputs.

ISO 23953-2 Standards Testing for Integrated Refrigerated Cabinets

ISO 23953-2 is the international standard governing the classification, construction, and performance of refrigerated display cabinets used in commercial food retail environments. 

Testing under this standard establishes how a cabinet performs under defined environmental conditions, measuring temperature maintenance, energy consumption, and Energy Efficiency Index (EEI) against standardised criteria.

Testing Framework & Conditions

Testing is rigorously structured to ensure cabinets can safely maintain specific food temperatures under controlled environments.

  • Standard Ambient Conditions: Tests are typically conducted in a controlled environment set at 25 degrees Celsius with 60% relative humidity (Climate Class 3).
  • Temperature Testing: M-packages (simulating food loads) equipped with thermocouples are placed inside the display area. The cabinet must maintain these packages within strict temperature limits based on the unit’s temperature classification.
  • Door Opening Tests: For cabinets with doors or lids, testing sequences mandate regular opening and closing during the test to simulate real-world usage.
  • Electrical & Energy Consumption: The cabinet’s energy use is calculated over a 24-hour period and used to determine its Energy Efficiency Index (EEI) and Star Rating.

Our low velocity parallel airflow chamber

This chamber is specifically designed for the testing of refrigerated display cabinets and conforms to the test room requirements specified in ISO 23953-2 and ISO 22041.

This unique test chamber is designed to provide consistent, stable operating conditions, no matter what equipment is under test.

The colour of the room, the number of lights, temperature control, humidity control, and low-velocity airflow all contribute to our ability to replicate ambient test conditions and airflow, every time.

Test room requirements for ISO 23953-2 are listed as follows; however our chamber can also achieve higher or lower temperatures, airflow rates and humidity levels.

  • 9 metres long × 5 metres wide × 3 metres high
  • Low-velocity, high-volume parallel airflow design
  • Air velocity range: 0.1 to 0.2 m/s
  • DB control temperature range: 16°C to 40°C +/- 1°C tolerance
  • Environmental control tolerance of +/-1°C temperature and +/-3% relative humidity
  • Humidity control range 40–80% RH

ISO 23953 2 sample reportYour test report

Once testing is complete, you  will receive a NATA-accredited ISO23953-2 report confirming the temperatures your cabinet reliably maintains, the food classification it qualifies for, and its measured energy use and Energy Efficiency Index (EEI) over a 24-hour cycle.

The results are independent, traceable, and recognised internationally through ILAC and the APAC MRA, giving you defensible evidence for compliance, energy labelling, tenders, and product claims, rather than self-declaration.
