Overview
IEC 60398:2015 is an international standard published by the International Electrotechnical Commission (IEC) that defines general performance test methods for installations used in electroheating (EH) and electromagnetic processing of materials (EPM). This third edition updates and expands upon previous versions by broadening the scope to include electromagnetic processing equipment, restructuring requirements, and emphasizing energy efficiency assessment. The standard provides foundational test procedures, conditions, and measurement techniques essential to evaluating industrial installations’ operational characteristics and energy performance.
Key Topics
-
Scope Expansion
The 2015 edition incorporates installations for electromagnetic processing of materials alongside electroheating, reflecting technological advances and industry needs.
-
Performance Testing Procedures
The standard defines basic test methods to assess key parameters such as energy consumption, power usage during different operational states (startup, standby, shutdown), equipment capacity, and temperature homogeneity.
-
Energy Efficiency Focus
New clauses and annexes address energy efficiency considerations, including:
- Methods for estimating energy use
- Assessment of energy recoverability from fluids
- Visual display of energy data through diagrams like Sankey charts
- Integration with ISO and IEC energy efficiency frameworks
-
Measurement Techniques
Guidance on precise measurement of electrical data (voltage, current, power), temperature (using thermocouples, thermographic methods), pressure, humidity, and workload parameters is included to ensure consistent and accurate testing.
-
Restructured Requirements
Safety-related tests have been moved to IEC 60519-1, enabling IEC 60398 to concentrate on operational performance and efficiency.
