SPECIFICATIONS, STANDARDS AND TECHNICAL DOCUMENTS

1. SCOPE
1.1 Scope. The tenns and abbreviations in this standard are limited
to those co111110nly used on drawings, and in specifications, standards,
and technical documents.
1.2 Aepl1cation. This standard provides a list of abbreviations
authorized for use on drawings, and in specifications, standards, and
other technical documents.
1.2.1 Short words. Abbreviations of words having five or fewer letters
are not included except those established by longstanding practice.
1.2.2 Field of use. Where an abbreviation is intended primarily for a
particular field of application, that field is indicated in parentheses
following the term, eg, fast operate (relay).
1.2.3 Combining form. Where two abbreviations are listed for the same
word, the first applies to the word used alone, while the one designated
(comb fonn) is to be used only in combination with abbreviations of other
words to fonn an abbreviation for a word combination.

3. DEFINITIONS
3.1 Abbreviations. An abbreviation is a shortened fonn or abridgment
of a word, expression or phase used to conserve space and time.
4. GENERAL REQUIREMENTS
4. l Clarity. Abbreviations shall be used only when their meanings are
unquestionably clear to the intended reader. WHEN IN DOUBT, SPELL IT OUT.
Abbreviations that are not in conman use and are to be used frequently
in a document or where there is doubt that the reader will understand their
meanings, should be clarified when first used: by spelling out the word
or complete phrase, followed by the abbreviation in parentheses.
4.2 Word combinations. Portions of an abbreviation for a word combination
shall not be separated for use singly. Single abbreviations may be
combined when necessary if there is no abbreviation listed for the combination.
4.3 Syntax. Unless otherwise indicated herein, the same abbreviation
shall be used for all tenses, the possessive case, participle endings,
the singular or plural, and the noun and modifying fonns of a tenn.
4.4 Capitalization. Abbreviations included in the left-hand column
provide the fonn for use on drawings and documents produced in upper-
case characters. The abbr�viations in the right-hand column provide the
form required for documents produced in lower-case characters; howP.ver,
these abbreviations may be capitalized when required for emphasis.
Abbreviations that are capitalized in the right-hand column are a contin­
uation of prior usage and in general are abbreviations for major systems
or are recognized as having significant application when used in text.
Abbreviations are not listed in the right-hand column for many short words.

viation which appears in the left-hand column shall be used except for the
s1Jbstitution of lover-case letters.

4.5 Punctuation.
4.5.l Punctuation marks which do not aooear in this standard shall not
be used with the abbreviation of a technical term; however, an abbrevia­
tion spelling a whole word should inc1ude a period if the abbreviation
is not obvious to its intended reader. An exception is made for abbrevia­
tions used in computer applications wherein a hyphen(-) may be sub­
stituted for a blank space which appears in an abbreviation. eg. 'seq­
chk' in lieu of 'seq chk'.
4.5.2 Hyphens should be used with adjectival forms of abbreviations and
symbols, eg, a 35-mm film.
4.6 Revised abbreviations. Abbreviations in this standard reflect
recent changes in the state-of-the-art.
4.7 Symbols. The distinction between abbreviations and symbols is
tricky, because it depends upon context, rather than form. For example,
"the current is 5 amps" and "the pressure is 3 psi are allowable uses of II

abbreviations, wh e reas writing "I= 5 amp 11 and "p = 3 psi" are incorrect.
Whenever a mathematical operation or sign is involved, such as the
equality sign(=) or the division sign(/)� abbreviations cannot be used.

me nts are preferred (for example, "the current is 5 A") in lieu of abbrevi­
ations that appear in this standard and shall be used in lieu of abbrev­
iations for terms that do not appear here in:

4.8 Abbreviations used in existing technical documents. Unless otherwise
specified, any changes or revisions to an existing dr�wing, �p�cificati?n,
standard, or technical document prepared under a previous ed1t1on of this
standard, may use the latest abbreviations, although the superseded
abbreviations may appear elsewhere in the document.
