Résumé

In the new revised norm, tests are conducted to determine a filter's fractional particle efficiency. The method provides greater knowledge about a filter's performance characteristics, making it possible to: evaluate filter performance properties in relation to IAQ requirements and process demands; find better agreement between lab test results and filter performance in real operating conditions; obtain a faster, simpler test method that is also easier to understand; use the same instruments and techniques for verifying filter performance in a ventilation plant.
