Overview
EN 305:1997 (CEN) - Heat exchangers: Definitions of performance and general test procedure - provides European-level guidance on the terminology, theory, calculations and a general test procedure used to determine the performance of heat exchangers. The standard is intended as a general reference that applies when cited by more specific branch application standards. It covers heat exchangers classified according to the heat transfer surface arrangements referenced in prEN 247:1996 (types 4.1 and 4.2).
Key topics and requirements
- Definitions and terminology: Standardized terms for describing heat exchanger performance and measurement results to ensure consistent reporting across manufacturers and test laboratories.
- Performance calculations and theory: General calculation methods and theoretical background used to determine thermal effectiveness, overall heat transfer rates and related performance indicators (presented as general principles rather than prescriptive formulas for specific models).
- General test procedure: A harmonized approach for conducting performance tests on heat exchangers, including measurement objectives, key test parameters and procedural steps applicable across different exchanger designs.
- Scope and applicability: Applies specifically to exchangers with surface arrangements defined in prEN 247:1996 (heat transfer surface types 4.1 and 4.2) and is intended to be used when referenced by industry-specific standards; application-specific standards take precedence for detailed requirements.
- Consistency and traceability: Emphasizes clear reporting of test conditions and results so performance data are comparable and traceable between suppliers, testing bodies and end users.
Applications and users
EN 305:1997 is useful for:
- Heat exchanger manufacturers preparing performance data and technical datasheets.
- Test laboratories and QA teams establishing general test setups and reporting methods for thermal performance.
- Design engineers in HVAC, boiler, chemical process and power industries who need consistent performance definitions for component selection and system modelling.
- Standards writers and certification bodies referencing general performance definitions when developing application-specific standards or conformity assessments.
Practical uses include establishing baseline test methods, ensuring consistent thermal performance reporting, supporting product comparison, and feeding reliable input data into system simulations.
Related standards
- prEN 247:1996 - referenced for heat transfer surface classification (types 4.1 and 4.2).
- Application-specific EN standards for boilers, HVAC equipment and process heat exchangers - these take precedence when they reference EN 305:1997.
