Numerical Markings
ATTACHMENT—   to   a   part,   assembly,   or subassembly,   designed   to   be   used   with   another assembly, unit, or set. It contributes to the effectiveness of the attachment by extending or varying the basic function of the assembly, unit, or set (e.g., hoisting attachment on a truck, milling attachment for a lathe). MAJOR COMPONENT— an item supported by an APL, but used in a larger item, such as an equipment. For  example,  the  meat  slicer  in  the  enlisted  dining facility is an equipment which is supported by an APL, and contains two components, the drive motor and the starter  motor,  both  supported  by  individual  APLs. MAJOR UNIT OR COMPONENT— a  component or segment of an equipment. For example, a radar set may have several major units, among them an amplifier, tuner, antenna pedestal, etc. ALTERNATE  NUMBER—  a type of reference number. Identification to an NSN is made normally by use of a primary reference number. Additional numbers that  can  be  used  to  determine  an  NSN,  such  as manufacturers’   part   numbers,   drawing   and   piece numbers, are referred to as alternate numbers. REFERENCE NUMBER— any number other than the current stock number, or circuit symbol in electronic equipments, used to identify a part. The most important reference  numbers  are  manufacturers’  part  numbers. Superseded stock numbers are also a type of reference number. Reference numbers are used in the Master Cross-Reference   List   (MCRL)   and   Coordinated Shipboard  Allowance  List  (COSAL)  to  determine  the NSN. COMMON ITEM— an item of standard design, application,  and  specification  normally  procurable from  several  manufacturers  or  suppliers,  or  available from only one manufacturer but with wide usage. Also an  item  that  may  have  multiple  applications. PRESENTATION  SILVER—  gifts of silver (a single  item  or  a  group  of  items)  occasionally  received by   U.S.   Navy   ships   from   states,   municipalities, organizations,   individuals,   or   other   sources.   (See NAVSUP  P485.) STOCK MEASUREMENT Accurate measurement of stock is very important. When identifying either material or requirements, you should consult the stock list to be sure you are making the  right  measurements  accurately.  For  most  purposes, a   steel   measuring   tape   is   accurate   enough.   For lightweight  sheet  metal  or  wire,  a  wire  and  thickness gauge is necessary. Stock identification lists contain tables for converting gauge to decimal or fractional parts of an inch. SYMBOLS AND MARKINGS As   an   aid   to   identification   and   as   a   safety precaution, many items are marked by symbols, codes, and serial numbers. SYMBOLS In addition to the NSN, symbols and color codes are used on certain metal products, and compressed gas cylinders.  These  are  used  primarily  by  technicians  to quickly identify these products and by you for storage purposes. In ordering and expending, the NSN should be  used. Metal Products Marking of iron and steel (ferrous) and other metal (nonferrous) products is covered by FEDSTD-1836, which provides for continuous marking. The  term  “continuous  identification  marking” means that the marking appears at set intervals on a piece of stock. It is put on with a heavy ink, similar to paint.  When  a  piece  of  bar  stock  is  cut,  each  piece should  carry  the  proper  identification.  The  markings must  give:  (1)  the  producer’s  name  or  registered trademark,  and  (2)  the  commercial  designation  of  the material. Marking   terms   for   the   various   commercial designations are found in FED-STD- 1836. Some iron and steel products are not included in the continuous  identification  marking  system  outlined  in FED-STD-1836. Required markings for these products are   included   in   the   material   specifications.   For example,  boiler  tubes  are  not  marked  continuously,  but Navy  specifications  covering  boiler  tubes  usually require that tubes of a certain size be marked at each end.   Smaller   tubes   than   those   covered   in   the specifications may be bundled and tagged. NAVSUP P485  and  FED-STD-1836  contain  information  on  how and where these markings must appear on various metal products. Compressed  Gas  Cylinders A common color code for compressed gas cylinders is  published  in  MIL-STD-101  and  NAVSUP  P-485  to provide   a   visual   warning   to   supplement   the 4-6
