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
