9、pplicable.1.9 Stack temperatures limitation for Test MethodAis approximately 400C (752F) and for Test Method B is 815C (1500F).1.10 A known limitation of these test methods concerns the use of collected residue data. Since some collected residues can beformed in the sample train by chemical reaction
10、 in addition to condensation, these data should not be used without priorcharacterization (see 4.4.1).1.10.1 A second limitation concerns the use of the test methods for sampling gas streams containing fluoride, or ammonia orcalcium compounds in the presence of sulfur dioxide and other reactive spec
