22h

22H is an alphanumeric designation used in several fields, where its meaning is determined by context. It does not denote a single concept, but rather a label applied in timekeeping, product naming, inventory, and referencing systems.

In timekeeping and scheduling, forms such as 22h or 22H appear in some European contexts to denote 22:00, with the "h" standing for hours. The capitalization varies with font and system, and in many cases the standard 24-hour format "22:00" is preferred. The 22H form is more common in compact labels on timetables, signage, or digital interfaces.

In manufacturing, consumer electronics, and automotive contexts, 22H may appear as a model number, version suffix, or batch code. It may indicate a revision, generation, or regional variant. Because manufacturers reuse short alphanumeric sequences, the same 22H label can refer to different products in different markets.

In libraries, archives, logistics, and data systems, 22H can serve as a code component within larger identifiers, such as catalog numbers or lot identifiers. In these contexts, the surrounding fields clarify its exact meaning.

Origin and usage: The term's versatility means that to determine what 22H signifies, one must consult the local context, accompanying documentation, or the database where the label appears.
