SECTION 2
FORM AND NUMBERING SYSTEM
1.
SCOPE
1.1 Scope. This section contains a brief description of the form and the system of numbering
within the individual methods, and also the manner in which new methods are added and old
methods revised.
2.
FORM
2.1 Revision of existing methods. The binding of this standard permits separation for
convenience in adding new methods and revising existing methods.
2.1.1 Numbering system used. When a technical change or modification is issued, one will
identify it by adding a decimal point to the basic method number or by incrementing the decimal.
2.1.2 Revision precedence. When a revision is issued on a Standard 141 method, it automatically
supersedes the previous method. Use the method of the particular revision in force at the time of
invitation to bid for testing.
2.2 New methods. A placement of new methods in this standard is based on the following
criteria:
a. The character or purpose of the test method indicates the specific section to which it
belongs.
b. A method number is assigned so that the new method is located close to methods of similar
or related type.
2.3 Use of ASTM test methods. American Society for Testing and Materials (ASTM) methods
listed in section 6 of this standard have been accepted as substitutes for the applicable canceled
Federal test methods and should be used whenever the Fed. Test Method Std. 141 method number
is referenced. When superseded 141 methods are to be cited in the future, the accepted ASTM
method should be cited directly.
3. INDEXES AND METHOD FORMAT

alphabetically by its primary purpose as indicated in its title.
