Summary o

16、f Test Method4.1 The total flue-gas exhaust from a solid fuel burningappliance is collected along with ambient dilution air with acollection hood. Duplicate sampling trains are used to extractgas samples from the dilution tunnel for determination ofparticulate matter concentrations. Each sample trai

17、n has twoglass fiber filters in series. The samples are withdrawn at aconsistently proportional rate from sampling points located atthe centroid of a sampling tunnel. During sampling, the filtersare maintained at a temperature less than 32 C (90 F). Themass of the sampled particulate matter is deter

18、mined gravi-metrically after the removal of uncombined water. The totalparticulate matter mass collected on the filters and in the probeand front filter housing are multiplied by the ratio of thedilution tunnel flow to sample flow to determine the totalparticulate emissions during a test.4.2 The sam

19、pling system for this test method consists ofduplicate dual-filter dry sampling trains. Both of the particulatesampling trains are operated simultaneously at a sample flowrate not to exceed 0.007 m3/min (0.25 cfm min). The totalparticulate results obtained from the two sampling trains areaveraged to

20、 determine the particulate emissions and are com-pared as a quality control check on the data validity.4.3 The particulate concentration results for each samplingtrain is adjusted by the particulate concentration result from asingle room air sample blank collected and processed the sameas the diluti

21、on tunnel particulate sampling trains described in4.2, except that only one filter is used in the sampling train. Ametering system as described in 6.1.1.4 shall be used todetermine the volume of room air collected. The sample flowrate shall not exceed 0.007 m3/min (0.25 cfm).4.4 Appliances tested by
