Scope: This Part of GB/T 25749 specifies the test bench method for measuring the mass separation efficiency of an air cleaning system with a conduit outlet under given operating conditions. The method is suitable for systems that purify air of aerosols (smoke, dust, soot, fine mist), vapors or gases. Measuring the mass separation efficiency of the air purification system used according to the intended purpose can be used for: a) evaluation of the performance of the air purification system; b) evaluation of the improvement of the air purification system; c) comparison between air purification systems; d) separation according to mass Classify the air purification system by efficiency; e) Determine the technical level of the air purification system for the same intended use according to the mass separation efficiency.
