Form and Style for ASTM Standards - ASTM International

method but too lengthy for inclusion in the main
text. Annexes shall precede appendixes.
Examples of such information are as follows:
A24.3.1 Glossary of terms used in the
method,
A24.3.2 List of symbols,
A24.3.3 Detailed description of apparatus,
A24.3.4 Instructions for calibrating and
standardizing apparatus,
A24.3.5 Directions for cleaning apparatus,
and
A24.3.6 Operating instructions and adjustments
of specific makes of apparatus.
A24.4 Appendixes— An appendix to an
ASTM standard is informative only and is not a
mandatory part of the standard. Information on
the following general subjects has been included
in such appendixes:
A24.4.1 Notes on significance and interpretation
of the test method, usually to amplify the
statement in the text,
A24.4.2 Development of equations used in
the calculations,
A24.4.3 Charts or supplementary information
for computations,
A24.4.4 Suggested data forms for recording
test results, and
A24.4.5 Commentary on rationale used in
the development of the test method.
A25. References
A25.1 Include only references to publications
supporting or providing needed supplementary
information. Historical and acknowledgment
references are not desirable. If there are five or
more references, list them in an unnumbered
section at the end of the standard in the order in
which they appear in the text. If there are fewer
than five literature references, use footnotes (see
Section G21).
A26. Footnotes
A26.1 General— Footnotes referenced in
the text are intended only for reference and shall
never include any information or instructions
necessary for the proper application of the
method. Table footnotes are a part of the table.
FORM OF ASTM TEST METHODS
A-13
Use consecutive superior numerals for reference
to footnotes except in connection with tables, in
which case use italic capital letters.
A26.2 Committee Jurisdiction and History—
Footnote 1 shall include in the first paragraph
the committee having jurisdiction and,
where the committee so requests, the subcommittee.
The second paragraph shall include history
information as follows: (1) approval date of latest
revision, (2) month and year of publication, (3)
designation and year of original issue, (4) designation
and year of previous issue, and (5) information
as to any other standards that may have
been replaced by the standard, year of redesignation,
etc.
A26.3 Literature References— Use footnotes
for references if there are fewer than five.
For five or more see Section A25, observing the
limitations noted therein. Also see Section G21.
A26.4 Sources of Apparatus— Where apparatus
may be special or not readily available from
more than one source, the source may be referenced.
(However, see Section F4 for detailed
rules.)
A26.5 Research Reports— Reference in a
footnote the availability of Research Reports (see
Section A29).
A27. Notes
A27.1 Notes in the text shall not include
mandatory requirements. Notes are intended to
set explanatory material apart from the text itself,
either for emphasis or for offering informative
suggestions not properly part of the standard.
Clarification of the description of required apparatus
or procedure and modifications required or
permitted in certain cases belong in the text itself.
If inclusion of the contents yields a different
result, then that information is considered mandatory
for the performance of the standard and shall
be located in the text. Notes may be preferable for
detailed description of auxiliary procedures (for
example, correction of barometric pressure in a
test method not primarily concerned with pressure).
Table notes are a part of the table and are
mandatory provisions.
A27.2 Notes appearing in a given standard
shall be numbered in sequence separately in the
main text, separately in sequence in the annex,
