Air purification devices for ventilation systems

1 Scope

China's national standard for air cleaning equipment used in ventilation and air conditioning systems. It specifies the terms and definitions, the classification and marking, the general requirements, the test methods, the inspection rules and the marking, packaging, transport and storage, and it applies to the manufacture and inspection of air purification equipment for ventilation and air conditioning. It was written into a particular moment: the severe urban particulate episodes of the 2010s made indoor air quality a mass concern in China, and air cleaning went from a specialist product for cleanrooms and hospitals to something fitted in offices, schools and homes. That expansion brought claims with it - percentages of removal, coverage areas, purification efficiencies - quoted without a stated test method and therefore without meaning. A standard that fixes how efficiency is measured, at what airflow, against what challenge, and how the result is expressed is what makes two products comparable, and it is the only defence a purchaser has against a number chosen by a marketing department.

This standard specifies the terms and definitions, classification and marking of general purpose, requirements, test methods for air purification systems for ventilation systems. Inspection rules and signs, packaging, transportation and storage. This standard applies to the production and inspection of air purification equipment for ventilation and air conditioning systems.
