2.3.3. INITIAL SCREENING AND CODIFICATION

Initial requests for codification are input in electronic media, by telecommunication means, e.g. AECMA Specification 2000M, for screening against the databases to reveal, by comparison of the reference numbers (part numbers), any IoS with an existing NSN. After initial screening, the IoS with no matching NSN by reference, in the codification database shall be codified. The resultant "Embryo NIIN" with its technical characteristics will be screened against the full codification database, where no match by characteristics is found, the IoS will be allocated a new NSN.
