TM 10-8400-203-23 25- Change 9 12 (10)  Outer Shell Replacement.  The outer shell of the base vest or any of the modular components may be replaced if they are extensively worn and appear not to be economically repairable.  The entire outer shell can be obtained from the manufacturer already fabricated.  See Section IV  for NSNs.  Replace the entire outer shell when the outer shell exhibits large holes or tears, is severely worn or soiled, or shows badly torn pockets or pocket flaps, or badly frayed collar.  If the outer shell is to be removed and replaced, it is important that the label containing the size, national stock number, and cleaning instructions be retained and stitched to the new shell. Check the ballistic panel size markings for legibility and remark if necessary.  If the label is unusable, replace it with a new one. 25-6.  TESTING Complete Vest. Dry Weight Test.  The dry weight test may be conducted to ensure that the OTV being returned to supply channels contains the proper size ballistic panel and the OTV size designation is correct.  The following table contains the weights of the OTV and SAPI in pounds.  The tolerance for each is 0.2 lbs.

(Army) Inspect the overall condition of the SAPI.  (Marine Corps) Inspect the overall condition of the SAPI prior to each field evolution and once per day during field use.  Check for rips or tears, surface cracks in the plate itself, or if the plate flexes and crunching sounds can be heard, or loose pieces can be heard inside plate when it is shaken. Each SAPI will be inspected to determine the proper classification in accordance with chapter 1, paragraph 1-7, and identification (item description, size and stock number).  (Marine Corps) If there are surface cracks in the plate itself, or if the plate flexes and crunching sounds can be heard, or loose pieces can be heard inside plate when shaken, the plate should be returned to the manufacturer. b.  (Marine Corps) The SAPI shall have a storage life of a minimum of 15 years when stacked no more than 7 plates high. CAUTION Do not use a stiff brush to clean any part of theSAPI as this will damage the material. c.  Cleaning Instructions. (1)  Remove loose dirt and lint from the outer surface of the SAPI using a cloth or soft bristle brush. (2)  Wet the SAPI in a sink or shower by running warm, not hot water over it.  Do not submerge it in a container of water. (3)  Apply a mild soap or detergent to the soiled areas and scrub with a cloth or soft bristle brush.  Badly soiled areas may be scrubbed with GI Soap.  Scrub only long enough to remove soil. (4)  Heavy grease and oil stains may be pre-spotted with a dry cleaning solvent and detergent mixture and scrubbed with a soft brush. (5)  Rinse the SAPI with warm water until all suds are completely gone.  Avoid immersing the SAPI in water. (6)  Let the SAPI dry by itself, away from heat or open flame. CAUTION Do not machine wash or dry.  Failure to follow these instructions may render your SAPI useless against ballistic threats.  Do not submerge your SAPI in a container of any liquid.
