This national standard specifies the inspection on the clean degree of Air Duct Systems in Heating Ventilating and Air-conditioning (HVAC) Systems (hereafter referred to as ventilating system), environmental control of projects, cleaning methods, and the reparation and replacement after cleaning, as well as the inspection on project monitoring and cleaning effect.
This national standard applies the cleaning of such Air Duct System in Heating Ventilating and Air-conditioning (HVAC) Systems as have been contaminative by dust particles and biologic factors and have no special requirement on air filtration.
