28.5. Item index — ISO 80000-10🔗

Every catalogued item of ISO 80000-10, indexed by its printed item number, with the principal quantity symbol, the coherent SI unit, and the PhysLib dimension this work assigns it. Each item number links to the formalized result it participates in. Symbols and unit strings are citation locators; nothing normative is reproduced.
