Heat exchangers - Methods of measuring the parameters necessary for establishing the performance
This European Standard specifies the methods and accuracy of measurement for temperature, pressure, fluid quality and massflow of different fluids and how to determine the pressure drops across a heat exchanger. Measurements are restricted to those necessary for establishing the performance of heat exchangers classified in prEN 247 using the fluids listed in prEN 247. This E.S. applies when reference by the various branch application standards. The specific application European Standards shall be the prime reference documents.
Wärmeaustauscher - Messungen und Meßgenauigkeit bei der Leistungsbestimmung
Die vorliegende Europäische Norm beschreibt Methoden und Messgenauigkeit für Temperatur, Druck, Fluidbeschaffenheit und Qassenstrom unterschiedlicher Fluide und wie der Druckabfall durch einen Wärmeaustauscher zu bestimmen ist. Die Messungen beschränken sich auf die, die für die Leistungsermittlung der in derEN 247 eingeteilten Wärmeaustauscher mit Hilfe der in EN 247 aufgeführten Fluide notwendig sind. Diese E.Norm gilt bei Verweisungen auch für verschiedenesich überschneidene Fachbereiche.
Echangeurs thermiques - Méthodes de mesurage des paramètres nécessaires à l'évaluation des performances
La présente norme européenne fait partie d'une série de normes européennes consacrées aux échangeurs thermiques. POur que le mesurage des performances d'unéchangeur thermique ait un sens, il est nécessaire que ce mesurage soit effectuéau moyen d'appareils, transducteurs et méthodes bien connues. La présente norme s'applique aux différents instruments, transducteurs, et méthodes de mesurage permettant le mesurage des températures, débits, pressions, et de la qualité desfluides des échangeurs thermiques.

Overview
EN 306:1997 - Heat exchangers - Methods of measuring the parameters necessary for establishing the performance - is a CEN European Standard that defines how to measure and report the parameters required to assess heat exchanger performance. The standard specifies measurement methods and the required accuracy for temperature, pressure, fluid quality and massflow, and for determining pressure drops across heat exchangers. Measurements covered are those necessary to establish performance for heat exchangers classified under prEN 247 and using the fluids listed in prEN 247.
Key topics and requirements
- Scope of measurements: Temperature, pressure, fluid quality (e.g., contamination or entrained gases), massflow and pressure-drop measurements essential to performance assessment.
- Measurement methods: Standardized procedures for placing sensors, selecting measurement points and obtaining representative operating values.
- Accuracy and uncertainty: Requirements for measurement accuracy and reporting of measurement uncertainty to ensure repeatable, comparable test results.
- Instrument selection and calibration: Guidance on appropriate instrument types, calibration practices and traceability to ensure reliable data.
- Test conditions and data recording: Rules for defining operating conditions, steady-state versus transient measurements and documentation required for performance verification.
- Limitation and referencing: Measurements are restricted to those needed for prEN 247 classifications; when conflicting or additional requirements exist, the specific application European Standards take precedence.
Applications and who uses EN 306:1997
EN 306 is practical for organizations and professionals involved in the design, testing, certification and procurement of heat exchangers:
- Heat exchanger and boiler manufacturers conducting performance tests and factory acceptance testing.
- Independent test laboratories and certification bodies performing standardized performance verification.
- R&D and quality assurance teams validating thermal performance and pressure-drop characteristics.
- HVAC, process engineering and utility procurement teams specifying verified performance data for system selection.
- Standards committees and regulatory authorities referencing consistent test methods for compliance and harmonized reporting.
