Summary of 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

10、 the dilution tunnel for determination ofparticulate matter concentrations. Each sample train 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 The samples are withdrawn at aconsistently proportional rate from sampling points located atthe centroid of a sampling tunnel.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 maintaine

11、d at a temperature less than 32C (90F). Themass of the sampled particulate matter is determined 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
