JJ MATERIAL.

The following Classification Index of Naval Stores and Material designates those classes under which the great majority of naval material falls.

For filing purposes in many activities by combining JJ (Material) with the class number, a file symbol can be obtained which will suffice for correspondence of a general nature. Further individual classification of materia] can be obtained by referring to the Index of Naval Specifications, the latest issue of which is available in the Supply Department of the nearest navy yard or naval station. These specification numbers preceded by the JJ (Material) symbol will give the complete file number for any particular commodity.

Specific symbols for certain commodities will be found in the JA to JZ group. These numbers for general correspondence should be used as they appear in the classification. For example: Helium--JC7; Iron and Steel JJ46-1.

Test reports on material and apparatus should be filed under the material groups, "Ships--S," "Shore--N," and "Aircraft--F," unless they are common to all, such as hose, metals, fuels, etc.
