  be used instead of Method 3B in appendix A-2 of 40 CFR part 60 to determine oxygen concentration.
\2\ All compounds quantified by Method 320 of appendix A to this part must be validated according to Section 13.0 of Method 320.
\3\ ASTM D6420-18 (incorporated by reference, see Sec.   63.14) may be used instead of Method 18 of 40 CFR part 60, appendix A-6 to determine total HAP
  emissions, but if you use ASTM D6420-18, you must use it under the conditions specified in Sec.   63.2354(b)(3)(ii).
\4\ ASTM D6348-12e1 (incorporated by reference, see Sec.   63.14) may be used instead of Method 320 of appendix A to this part under the following
  conditions: the test plan preparation and implementation in the Annexes to ASTM D6348-12e1, Sections A1 through A8 are mandatory; the percent (%) R
  must be determined for each target analyte (Equation A5.5); %R must be 70% >= R <= 130%; if the %R value does not meet this criterion for a target
  compound, then the test data is not acceptable for that compound and the test must be repeated for that analyte (i.e., the sampling and/or analytical
  procedure should be adjusted before a retest); and the %R value for each compound must be reported in the test report and all field measurements must
  be corrected with the calculated %R value for that compound by using the following equation: Reported Results = ((Measured Concentration in Stack))/
  (%R) x 100.
