EN 12830 Standard Requirements for Refrigerators and Freezers

Measurement Accuracy

• Temperature: ±1°C across the entire operating range.
• Humidity: ±3% humidity across the entire operating range.

Measurement Frequency

• Specifies the measurement frequency for temperature and humidity.
• Selected to cover hazardous conditions yet flexible enough to meet application requirements without unnecessary measurements.

These requirements ensure not only accuracy but also the appropriate frequency of measurements to meet the needs of the application without unnecessary burden on the system.

Data Management

• Data Storage: Data resulting from measurements must be stored for an appropriate period.
• Data Retrieval: The standard allows for the retrieval of stored data, crucial for verification, analysis, and utilization of measurements.
• Controlled Access: The standard may specify measures for controlled access to data to protect against unauthorized access.
• Reports and Documents: Preparation of reports and documents related to measurements, data, and operating conditions is required for transparency and reliability.
• Malfunction Detection: Detecting malfunctions is crucial for immediate response to potential issues, protecting refrigeration equipment, and maintaining suitable conditions. Needs for anomaly detection may include:
• Alarms and Notifications: Installation of alarm mechanisms and notifications in case of irregularities or exceeding temperature and humidity limits.
• Automatic Recording of Malfunctions and Events: A system for the automatic recording of events to be available for future analysis.
• Data Analysis: Applying data analysis methods to identify proposed patterns and anomalies in measurements.
• Functionality Tests: Procedures for checking and testing functionality to ensure the proper operation of measurement systems.
