Method
Published by U.S. General Services Administration (federal specifications) (GSA)
The CFR incorporates Method by reference, which makes the edition it names part of the regulation. The CFR requires the edition it names, which may not be the newest. To enforce any other edition, the agency must publish the change in the Federal Register.
