Overview
EN ISO 6369:2023 (ISO 6369:2023) - titled Ice makers for commercial use - Classification, requirements and test conditions - defines standardized methods to measure energy consumption, water consumption, ice production capacity, and harvested ice characteristics of commercial ice makers with built‑in condensing units. Published by CEN and prepared by ISO/TC 86 in collaboration with CEN/TC 44, this standard is intended for factory‑made ice makers used in commercial settings.
Note: it does not apply to ice makers for household appliances or units with remote condensing units.
Key topics and technical requirements
- Scope & definitions: clear classification of appliance types (self‑contained, modular, split), condenser cooling (air‑cooled, water‑cooled), ice types (cubes, flakes), and production modes (batch vs continuous).
- Measurement methods: standardized procedures for determining:
- Ice production capacity (test set‑up, stabilization and sampling),
- Energy consumption (instrumentation, power supply and recording),
- Water consumption (potable and condenser cooling water measurements),
- Harvested ice characteristics using calorimetry (equipment, calorimeter constant and net cooling effect).
- Test environment & setup: guidance on test room conditions, ambient temperature, water supply, unit location, and set‑up/operation protocols to ensure repeatable results.
- Instrumentation & accuracy: requirements for measurement accuracy, calibration and recording procedures.
- Reporting: information to be declared by manufacturers or test laboratories (performance data and test conditions).
Applications and who uses it
- Manufacturers use EN ISO 6369:2023 to design, rate and declare performance of commercial ice makers.
- Test laboratories and certification bodies adopt the standardized test methods for product verification and compliance testing.
- Purchasing/specifying professionals (foodservice operators, hospitality chains, retailers) rely on standardized performance data to compare models and select energy‑ and water‑efficient equipment.
- R&D and quality teams use the calorimetry and production tests to assess ice quality and optimize designs.
Related standards and context
- Prepared under ISO/TC 86 and CEN/TC 44 (Vienna Agreement), EN ISO 6369:2023 aligns with international refrigeration testing practice. It complements other commercial refrigeration and energy‑efficiency standards and is indexed under ICS 97.130.20 (commercial refrigerating appliances).
