Reference designation lists
Individual reference designation lists are provided for:
• assemblies that are assigned an alpha-prefixed Nautel nomenclature (e.g., NAPC147D)
• cable harnesses that are assigned a numbered Nautel part (e.g., 202-8005-01)
• optional kits that are assigned a numbered Nautel part.
To obtain the full reference designation for a specific part the Nautel configuration control number
must be located in the family tree (see
Figure 3.1 on page 3-6 ) to include the reference designation of
all higher level assemblies. The reference designation lists, which are titled and presented in
alphanumeric order, are divided into columns to aid in locating specific information.
Column content
The following paragraphs provide an explanation of the purpose and contents of each column in the
part number indexes.
Ref des column
The 'ref des' column contains the reference designation for a specific part. These designations are
assigned in accordance with the requirements of American National Standard Specification ANSI
Y32.16.
Description column
This column contains the name and descriptive information for each part. The key word is presented
first, followed by the adjective identifiers. When the description is See
Family Tree for Assembly
Nomenclature , the associated part is subject to its own part index table or is contained in an optional
kit's list. Look up the reference designation list title (nomenclature) and the reference designation of
the associated part in the family tree (
Figure 3.1 on page 3-6 ) to determine where to locate its part
information.
Nautel # column
This column contains the Nautel number assigned to each part. This number is Nautel's drawing
number for Nautel manufactured parts, Nautel's configuration control number for assemblies that are
under configuration control management, or Nautel's inventory management number for purchased
parts. When a Nautel configuration control number (e.g. NAPC*) is referenced in this column, the
associated ref des item is subject to its own part index table.
