BS ISO 11155-2:2009 Road vehicles. Air filters for passenger compartments. Test for gaseous filtration

BS ISO 11155-2 specifies a test comprising several methods for measuring the dynamic gas adsorption of air filters in the passenger compartments of road vehicles.

The laboratory test methods in BS ISO 11155-2 are applicable to air filters that improve air quality by reducing concentrations of gaseous, odorous or hazardous components from ambient or re-circulated air, or both, in the vehicle cabin. They provide a means of measuring air pressure loss, as well as gas and vapour removal characteristics.
