- EN 308 is the European standard that specifies test procedures for air-to-air heat transfer in heat recovery equipment. Rather than setting a pass/fail threshold, it defines how to measure temperature effectiveness and, for enthalpy devices, moisture effectiveness under controlled inlet conditions.
- The test fixes inlet dry-bulb temperatures and, where relevant, humidity on both streams, then calculates effectiveness from the measured outlet states. Balanced and unbalanced airflow cases are both reported so designers can read real-world performance. This is the method referenced by EN 16798 energy calculations.
- Because EN 308 is a test method, the actual performance thresholds come from the building regulations and standards (EPBD, EN 16798) that cite it. Always check the local code for the minimum effectiveness it requires.
- A consistent test method lets you compare a European plate exchanger and a rotary wheel on the same footing, and it underpins Eurovent certification of published performance.

EN 308 specifies how to test air-to-air heat exchangers to determine temperature effectiveness and, for enthalpy devices, moisture effectiveness under controlled inlet conditions. Is EN 308 a performance requirement? No, it is a test method; the thresholds come from EN 16798, EPBD and local codes that reference it.
