Stocked item; use the applicable NSN to request/requisition
items with these source codes. They are authorized to the
category indicated by the code entered in the 3d position
of the SMR code.
**NOTE: Items coded PC are subject to deterioration.
Items with these codes are not to be requested/requisitioned
individually. They are part of a kit which is authorized to
the maintenance category indicated in the 3d position of
the SMR code. The complete kit must be requisitioned
and applied.
Items with these codes are not to be requested/
requisitioned individually. They must be made from
bulk material which is identified by the part number
in the DESCRIPTION AND USABLE ON CODE (UOC)
column and listed in the Bulk Material group of the
repair parts listed in this RPSTL. If the item is
authorized to you by the 3d position code of the SMR
code, but the source code indicates it is made at a
higher level, order the item from the higher level of
maintenance .
