Overview
ISO 22042:2021/Amd 1:2024 is the latest amendment to the international standard for blast chiller and freezer cabinets used in professional settings. This amendment updates the classification, performance requirements, and testing conditions to ensure reliable, energy-efficient, and consistent operation of these refrigeration units. Developed by ISO Technical Committee ISO/TC 86 in collaboration with European counterparts, this standard amendment enhances the protocols used by manufacturers, testers, and users for evaluating blast chillers and freezers.
Key Topics
- Classification and Definitions
The amendment refines key terms such as "test load" to specify the total weight of test food used during performance assessments.
- Performance Testing Conditions
- Blast chillers must cool test food to the final temperature within 120 minutes.
- Blast freezers have a longer allowable cooling time of 270 minutes for the test food.
- Load Consistency Requirements
Test loads for chilling and freezing cycles should not deviate by more than 3% from the full load capacity, ensuring standardization of test conditions.
- Measurement Frequency
Temperature measurements in both the test room and food samples (M-pans) must be recorded at least every 5 minutes, enabling precise tracking of cooling performance.
- Energy Consumption Calculation
Calculations should be based on the full load capacity, providing accurate insights into energy efficiency under realistic usage scenarios.
- Reporting Updates
The amendment modifies the information report formats to enhance clarity and alignment with updated classification and testing data.
Applications
- Professional Kitchens and Catering
Ensures blast chillers and freezers comply with required cooling rates and quality standards, preserving food safety and extending shelf life.
- Equipment Manufacturing and Testing
Provides manufacturers with clear, standardized protocols to design, test, and certify blast chilling and freezing units for consistent international compliance.
- Regulatory and Compliance Assessment
Assists certification bodies and food service establishments in verifying equipment meets energy consumption and performance requirements.
- Energy Efficiency Improvements
Enables the design of more sustainable refrigeration solutions by applying standardized test loads and measurement procedures.
