ISO 639-1:2002 pdf download.Codes for the representation of names of languages — Part 1: Alpha-2 code.
To ensure continuity and stability, language identifiers shall only be changed for compelling reasons. After a change in identifiers, the previous identifier shall not be reassigned for at least ten years, and only after careful consideration and approval by the Joint Advisory Committee (see annex A).
When adapting this International Standard to languages using other writing systems (e.g. the Cyrilic alphabet), language identifiers shall be formed according to the principles of this part of ISO 639.
A single language identifier is normally provided for a language even though the language is written in more than one script. A separate standard may be developed for the purpose of designating information concerning the script or writing system of a language.
4.2 Registration for new language identifiers
Everyone is free to apply for or propose a language to be coded in ISO 639-1. Each application or proposal shall be accompanied by the following:
a) documentation relevant to the scope of ISO 639-1 (clause 1 of this part of ISO 639);
b) a recommendation and support of an authority (standards organization, governmental body, linguistic institution, or cultural organization).
The selection of a code element for inclusion in the two-letter code is primarily based on the existence of a substantial body of documentation written in specialized languages as well as of a number of terminologies in various subject fields.
All code elements in the two-letter code are also included in the three-letter code and shall meet the selection criteria specified in ISO 639-2. Furthermore, the following selection criteria shall be considered:
— the number of speakers of the language community;
— recognized status of the language in one or more countries;
— the support by one or more official bodies.
