Stable section ID: S05-CON-015-SECTION-14 · 5 content blocks
An abbreviation is a shortened form of a word or phrase. An acronym is an abbreviation pronounced as a word. An initialism is formed from initial letters pronounced individually. A symbol is a controlled graphical or alphanumeric representation of a quantity, entity, operation, state, or relationship.
Each controlled abbreviation, acronym, initialism, or symbol shall possess one approved expansion or meaning within its declared scope.
The full term should appear at first use, followed by the approved shortened form in parentheses, unless the shortened form is universally established within the applicable document family.
The same abbreviation or symbol shall not represent multiple concepts within the same scope. Case, punctuation, subscripts, superscripts, and typography shall be preserved where they affect meaning.
Symbols for units and mathematical quantities shall follow applicable recognized standards. Abbreviations shall not be pluralized or modified in a manner that creates uncertainty unless the approved terminology record explicitly permits that form.
