TM    9-2815-210-34P N O T E When you use a NSN to requisition an item, the item you receive may have a different part number from the part ordered. f.  Description  and  Usable  on  Code  (UOC)  (Column  (6)).  This  column  includes  the  following information: (1) The Federal item name and, when required, a minimum description to identify the item. (2)  Items  that  are  included  in  kits  and  sets  are  listed  below  the  name  of  the  kit  or  set. (3) Spare/repair parts that make up an assembled item are indented and listed immediately following the   assembled   item   line   entry. (4)  Part  numbers  for  bulk  materials  are  referenced  in  this  column  in  the  line  item  entry  for  the  item  to be  manufactured/fabricated. (5)  When  the  item  is  not  used  with  all  serial  numbers  of  the  same  model,  the  effective  serial  numbers are  shown  on  the  last  line(s)  of  the  description  (before  UOC). (6)  The  UOC,  when  applicable  (refer  to  paragraph  5,  Special  Information). (7)  In  the  Special  Tools  List  section,  the  Basis  of  Issue  (BOI)  appears  as  the  last  line(s)  in  the  entry  for each special tool, special TMDE, and other special support equipment. When density of equipment supported exceeds   density   spread   indicated   in   the   Basis   of   Issue,   the   total   authorization   is   increased   proportionately. (8) The statement END OF FIGURE appears just below the last item description in column 5 for a given  figure  in  both  Section  II  and  Section  III. g. QTY (Column (7)). QTY (quantity per figure column) indicates the quantity of the item used in the breakout  shown  on  the  illustration  figure,  which  is  prepared  for  a  functional  group,  subfunctional  group,  or an  assembly.  A  V  appearing  in  this  column  in  lieu  of  a  quantity  indicates  that  the  quantity  is  variable  and the   quantity   may   vary   from   application   to   application. 4.  Explanation  of  Columns  (Section  IV). a. National Stock Number (NSN) Index. (1)  Stock  Number  column.  This column lists the NSN by National Item Identification Number (NIIN) N S N sequence.  The  NIIN  consists  of  the  last  nine  digits  of  the  NSN  (i.e., 5305-01-674-1467). When using this column NIIN to  locate  an  item,  ignore  the  first  4  digits  of  the  NSN.  However,  the  complete  NSN  should  be  used  when ordering items by stock number. (2)   Fig.   column.  This   column   lists   the   number   of   the   figure   where   the   item   is   identified/located. The  figures  are  in  numerical  order  in  Section  II  and  Section  III. (3) Item column. The item number identifies the item associated with the figure listed in the adjacent  FIG.  column.  This  item  is  also  identified  by  the  NSN  listed  on  the  same  line. b. Part Number Index.  Part numbers in this index are listed by part number in ascending alpha- numeric   sequence   (i.e.,   vertical   arrangement   of   letter   and   number   combination   which   places   the   first   letter or  digit  of  each  group  in  order  A  through  Z,  followed  by  the  numbers  0  through  9  and  each  following  letter or digit in like order). (1)  CAGEC  column.  The  Commercial  and  Government  Entity  Code  (CAGEC)  is  a  5-digit  numeric code  used  to  identify  the  manufacturer,  distributor,  or  Government  agency,  etc.,  that  supplies  the  item. (2)  Part  Number  column.  Indicates  the  primary  number  used  by  the  manufacturer  (individual, company,   firm,   corporation,   or   Government   activity),   which   controls   the   design   and   characteristics   of   the item   by   means   of   its   engineering   drawings,   specifications   standards,   and   inspection   requirements   to   identify an  item  or  range  of  items. 4
