Air filters for general ventilation - Determination of the gravimetric efficiency and the air flow resistance versus the mass of test dust capturedWhat is ISO 16890 3 Air filters for general ventilation about? ISO 16890 discusses air filters for general ventilation. ISO 16890 3 is the third part of the ISO 16890 multi series and discusses the gravimetric efficiency and the airflow resistance versus the mass of test dust captured. ISO 16890 3 specifies the test equipment and the test methods used for measuring the gravimetric efficiency and resistance to airflow of air filters for general
