1 Subject Content and Application Scope 1.1 Subject content This standard specifies the gravimetric method for the determination of total suspended particulates. 1.2 Application scope This standard is applicable to the determination of total suspended particulates in air with large or medium flow-rate total suspended particulates sampler (hereinafter referred to as “sampler”). The detection limit of this method is 0.001 mg/m3. This method is not applicable where the total suspended particulates content is overhigh or the resistance for filter membrane is larger than 10kPa in foggy day. 2 Principle Extract quantitative volume of air at constant speed with the sampler equipped with specific cutting characteristic; the suspended particulates with particle size less than 100μm will be intercepted in the filter membrane with constant weight. Calculate the concentration of total suspended particulates according to the sampling volume and the weight difference of filter membrane before and after sampling. Proximate analysis is carried out after the treatment for filter membrane.
