b14

B14 is a designation used in a variety of contexts, with no single, universal meaning. The interpretation of B14 depends on the domain in which it appears.

In transportation and urban infrastructure, B14 commonly designates a bus line or route number. Different cities and transit agencies assign B14 independently, so the exact service, route map, and operator vary widely.

In science, engineering, and manufacturing, B14 may appear as a model or part number. It can denote a specific device, component, or product line within a manufacturer's catalog. In radiochemistry or nuclear science, B-14 can refer to an isotope designation (boron-14) used in research and theoretical calculations; such isotopes are typically short-lived and studied in specialized contexts.

In historical nutrition literature, B14 has occasionally appeared as a proposed vitamin label beyond the standard B1–B12 series. However, B vitamins beyond B12 are not recognized in contemporary nutritional science, and B14 is not part of official nomenclature.

Because of its cross-domain use, the meaning of B14 must be inferred from accompanying information such as the field, organization, or product context. See also disambiguation pages for B-series designations and line numbers.
