1 Scope
This standard specifies minimum allowable values of energy efficiency and energy efficiency grades for air cleaners as well as their test and calculation methods.
This standard is applicable to air cleaners with rated voltage not greater than 250 V and certain purifying capacity of particles (clean air delivery rate of particles is 50 m3/h~800 m3/h).
This standard is not applicable to:
——air cleaner adopting ion generating technology only;
——airway-type air cleaning unit and other similar air cleaners;
——air cleaner having purifying capacity of gaseous pollutants and microorganisms;
——air cleaner specially designed for industrial use, medical use and vehicles;
