MATERIAL IDENTIFICATION LEARNING   OBJECTIVE:   Identify   and understand  the  terminology  used  in  aviation supply . If all publications and all types of situations were presented  here,  this  training  manual  (TRAMAN) would be extremely large. Therefore, this chapter TERMINOLOGY USED IN THE SUPPLY  CATALOGING  SYSTEM Before  you  can  find  information,  you  must understand supply terms.

Alphanumeric   sequence.   An   alphanumeric sequence begins at the extreme left-hand position of a number and continues from the left to the right, one position at a time, until all digits have been considered. The order of digit precedence for the part number begins at the left and moves to the right. It begins with A,  and  then  the  other  letters  in  alphabetic  sequence through Z. (The letter O is considered a numeric zero.) After  the  letter  Z,  the  numbers  0  through  9,  in sequence, have precedence. Diagonal lines (/), points (.),  and  dashes  (-)  can  be  used  in  the  second  or succeeding positions of the part number. When used, they  take  precedence  over  letters  and  numbers,  and come before the other part numbers that have letters or numbers. 3-3
