FED-STD-228A
SECTION 2
FORM AND NUMBERING SYSTEM
1.
SCOPE
1.1 Scope. This section contains a brief description of the from and the system of numbering within
individual methods, and also the manner in which new methods are added and old methods revised.
2.
FORM
2.1
Revision of existing methods. When a technical change or modification is issued, it will be
identified by adding a decimal point to the basic method number or by increasing the decimal by one digit;
e.g., 3111, if modified or changed, would be 3111.1; and 2011.1, if modified or changed, would be
2011.2.
2.1.1 Revision precedence. When a revision is issued on a Standard 228 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.
2.1.2 Numbering system used. When a technical change or modification is issued, it will be identified by
adding a decimal point to the basic number or by incrementing the decimal.
2.2 New methods. A method number will be assigned so that the new method is located close to
methods of similar or related tests.
2.3 Use of ASTM test methods. American Society for Testing and Materials (ASTM) methods listed in
section 7 of this standard have been accepted as substitutes for the applicable cancelled Federal test
methods and should be used whenever the Fed. Test Method Std. 228 method number is referenced.
When superseded 228 methods are to be cited in the future, the accepted ASTM method should be cited
directly.
3. INDEXES AND METHOD FORMAT
3.1 The indexes.
3.1.1 Alphabetical index (section 3). In the alphabetical index, each current method is listed
alphabetically by its primary purpose as indicated in the title.
3.1.2 Numerical index (section 4). The numerical index lists all current methods in numerical order.
3.1.3 Subject index (section 5). The subject index lists all current methods by subject.
3.1.4 Numerical index of cancelled references (section 6). An index of cancelled, deleted, or superseded
test methods is listed with cross-reference to the superseding Fed. Test Method Std. 228 or accepted
ASTM test methods where applicable.
3.1.5 Numerical index of accepted ASTM test methods (section 7). The ASTM test methods accepted
are listed with cross-reference to cancelled Fed. Test Method Std. 228 test methods.
