# §761.320. Applicability.


This subpart describes self-implementing comparison testing requirements for chemical extraction and chemical analysis methods used as an alternative to the methods required in [§ 761.272](/cfr/40/761.272.md) or [§ 761.292](/cfr/40/761.292.md). Any person conducting comparison testing under this subpart must comply with the requirements of [§ 761.80(i)](/cfr/40/761.80.md?p=i), including notification. Use alternative methods only after successful completion of these comparison testing requirements and after documentation of the results of the testing.
