Method 202 is an isokinetic sampling method used to measure Condensable Particulate Matter (CPM) from stationary source emissions
Methods 5, 17, and 201A are relevant to performing Method 202. To meet the requirements of the filterable PM test method used in conjunction with Method 202, you must maintain isokinetic sampling conditions. In addition, you must sample at the required number of sampling points, which are specified in Method 5 of appendix A-3 to part 60, Method 17 of appendix A-6 to part 60, or Method 201A of appendix M to this part.
The CPM is collected in dry impingers after filterable PM has been collected on
a filter maintained as specified in either Method 5 of appendix A-3 to part 60, Method 17 of
appendix A-6 to part 60, or Method 201A of appendix M to this part. The organic and aqueous
fractions of the impingers and an out-of-stack CPM filter are then taken to dryness and weighed.
The total of the impinger fractions and the CPM filter represents the CPM.
