ISO 22041:2019 PDF

Overview

ISO 22041:2019 - Refrigerated storage cabinets and counters for professional use - Performance and energy consumption - defines how to verify performance and measure energy consumption of refrigerated cabinets and counters intended for professional food storage. It sets out test conditions, measurement methods, classification by temperature and duty, marking and the manufacturer-declared characteristics. The standard applies to equipment used in commercial kitchens, hospitals, canteens, bakeries, gelateria, bars and institutional catering, but excludes display cabinets, certain processing appliances, appliances with remote condensers or water-cooled condensers, chest freezers, built-in/roll-in/pass-through cabinets, and ice-cream freezers.

Key topics

• Scope and exclusions: clear list of appliances and situations not covered (e.g., direct-sale display cabinets, open-top saladettes, appliances with remote condensing units).
• Test conditions and methods: standardized procedures for temperature tests and electrical energy consumption tests to ensure repeatable, comparable results.
• Temperature classification: use of M-packages and climate classes to classify chilled and frozen storage performance.
• Duty categories: definitions for semi-professional (light), normal and heavy duty cabinets with associated test climates.
• Defrosting and condensate handling: requirements and classification of defrost methods (automatic, semi-automatic, manual) and condensate drainage capacity and accessibility.
• Physical and marking requirements: net volume, load limit/label marking, shelf and drawer definitions, and the list of characteristics manufacturers must declare (including E24h energy consumption).
• Terminology: standardized definitions (vertical vs counter cabinets, static air cabinets, combined/multi-use cabinets), ensuring consistent interpretation across stakeholders.

Applications

ISO 22041:2019 is practical for:

• Manufacturers - design verification, performance development, product documentation and declared energy figures.
• Test laboratories - reproducible test setups and reporting for certification or R&D.
• Specifiers & procurement - writing technical specifications and comparing products on the basis of verified temperature performance and energy use.
• Energy managers & facility operators - selecting energy-efficient refrigerated furniture for commercial kitchens, hospitals and catering facilities.
• Regulatory bodies & certification schemes - harmonized test methods for labeling and compliance activities.

Related standards

• Developed under ISO/TC 86 (Refrigeration and air-conditioning). The document contains no normative references but aligns with general ISO/IEC editorial rules and terminology resources (IEC Electropedia, ISO OBP) for consistent vocabulary.
