A013

A013 is a designation used as an alphanumeric identifier across multiple domains. It does not refer to a single concept, but rather functions as a code assigned by different organizations to label an item, part, record, or dataset within a specific system. The exact meaning is contingent on the context in which it appears.

In manufacturing and commerce, A013 commonly appears as a model number or part code within a product catalog. Depending on the company, it may denote an electronic component, a mechanical part, or an accessory. Such codes support inventory control, ordering, and service documentation by providing a compact reference that can be linked to specifications and drawings.

In libraries, archives, and digital repositories, A013 may serve as a call number, accession number, or catalog identifier. It helps locate a particular item within a broader collection and can be unique to a collection or shared across related records.

In software, data management, and standards work, A013 can identify a test case, a dataset variant, a version tag, or a clause in a specification. The exact definition is defined in the relevant metadata or documentation.

Disambiguation requires checking the originating source—for example, a catalog entry, a data dictionary, or a standards document—to determine what A013 refers to in that context.
