This part of ISO/IEC 15459 specifies the procedural requirements to maintain identities and outlines the obligations of the Registration Authority. This part of ISO/IEC 15459 excludes those entities where ISO has designated Maintenance Agencies or Registration Authorities to provide identity and/or identifier schemes. It does not apply to: — freight containers, because their unique coding is specified in ISO 6346, Freight containers — Coding, identification and marking; — vehicles, because their unique identification is specified in ISO 3779, Road vehicles — Vehicle identification number (VIN) — Content and structure; — car radios, because their unique identification is specified in ISO 10486, Passenger cars — Car radio identification number (CRIN). The exclusion also applies to: — ISO 2108, Information and documentation — International standard book number (ISBN) and ISO 3297, Information and documentation — International standard serial number (ISSN); NOTE The scope of each of ISO 2108 and ISO 3297 identifies the title rather than the individual copy of a book or periodical. As such, the level of identification achieved is at a level similar to the unique identity as defined in ISO/IEC 15459-6. Individual copies of a title (book or periodical) may be identified using ISO/IEC 15459-4.
