Ventilation for buildings. Correction of air flow rate according to ambient conditions Ingestion-build-54484 BS EN 1926 specifies aWhat is PD CEN TS 17153 Ventilation for buildings about? PD CEN TS 17153 discusses ventilation for buildings. PD CEN TS 17153 gives guidelines to correct the measured airflow rate when measuring conditions are different from standard conditions. It applies to a power law formula giving the airflow rate as a function of a pressure difference with an airflow rate coefficient, C, varying with temperature and pressure. PD CEN TS 17153 applies to: Passive
