Test methods

The methods carry an xx, 1xx, 2xx, or 3xx alphanumeric designation. The xx, 1xx, and 3xx numbered methods are directly cited by specific regulations for determining compliance under 40 CFR Parts 60, 61, and 63, and may be used by sources for application as cited by the regulations and the method itself without further EPA approval.

The 2xx series methods are promulgated to facilitate incorporation in applicable State Implementation Plans. The 2xx methods, like the xx, 1xx, and 3xx series methods, include quality control and quality assurance procedures that must be met.

Federal Register proposed test methods have been published in the Federal Register as proposed rules, but have not yet been promulgated.

On each test method page, there is a printable version of the method in PDF.
