1. THE NATO CODIFICATION SYSTEM:

1.6. ELEMENTS OF THE SYSTEM:

1.6.2. ITEM NAMES

To ensure uniformity the System employs rules for naming each IoS using Approved Item Names (AIN). These AINs are defined in National Codification Handbooks (H-6) and ACodP-3. Approved Item Names are published together with their definitions and Item Name Codes (INC) and are used for classification of Items of Supply (see Paragraph 1.6.1) and descriptive identification of IoS and, where applicable, for reference identification of IoS (see Paragraph 1.6.3). The H-6 also defines colloquial names which are cross-referenced to Approved Item Names. When a manufacturer's Item Name cannot be related to an Approved Item Name, it may, exceptionally, be used as a Non-Approved Item Name (NAIN). The naming and nomenclature of an IoS is crucial to future linkage between the NCS and emerging international standards such as ECCMA, UNSPSC, PLib, STEP and PLCS. 

AC/135 has published online a Multilingual NATO IoS Name Directory, known as Allied Codification Publication No 3 (ACodP-3), a comprehensive and internationally agreed dictionary of Approved Item Names required in the preparation of all IoS identifications. A National Codification Bureau having a requirement for an IoS Name not included in ACodP-3 must request its assignment in accordance with prescribed rules. However, H-6 handbooks are still maintained by several nations to serve as guides for IoS identification in their own language. Approved Item Names and related codes in the national H-6 handbooks conform to ACodP-3.

Each Approved Item Name is referenced in the ACodP-3 to one or more NSC codes.
