Activated Carbon for Odor Removal from Ventilating Systems
Applies to activated carbon material for use in air filters
intended for the removal of odors from air streams in heating,
air-conditioning and ventilating systems. This standard
identifies the physical characteristics and performance
requirements of new or reactivated carbon used in carbon air
filter units as component parts of heating, air conditioning and
ventilating systems.
