Figure A-1. Label Information

Labels should provide a concise and meaningful verbal description of the function (noun name) of

the item being identified. Labels should also provide a unique alphanumeric code identifying the

system and the component. In some facilities, particularly where duplicate systems or parallel

trains of equipment are used, additional identifying information may be required to ensure that

each label uniquely identifies a single component.

Noun names and alphanumeric codes used on labels should be consistent with those used in

procedures, drawings, and other facility documents. Any abbreviations or acronyms used in noun

names, system designator codes, or component function codes should be standardized, commonly

understood, and identified on the facility approved list. It may be helpful to list systems and

components by name and by designator to make it easier for personnel to locate the correct name

associated with a label code, as illustrated in the following tables.
