What is the timeline used for approving new ISO 639 language codes?
After a request for a new, deleted, or changed code is submitted to the appropriate registration authority (Infoterm for 639-1 and Library of Congress for 639-2), the appropriate registration authority determines whether or not the request meets the relevant criteria. The registration authority then informs the requester of the process generally within two weeks of the submission. If the request meets the criteria, the registration authority determines an appropriate code and consults the ISO 639/JAC. If the first vote is not unanimous, a second round of voting is conducted. The original requester will be informed of the JAC decision in six weeks to two months from submission of the original request. Results of the JAC decisions will be publicized in a change notice available on the Web. In general, changes to the ISO 639-3 code set that do not affect the Part 2 code set are processed according to an annual review calendar. However, a change that affect both ISO 639-2 and ISO 639-3 is
