3-8. INSPECTION 3-9. TESTING TM  10-8400-203-23 The inspection or quality control element is responsible for determining compliance with repair instructions and requirements for classification. In-process inspections will be performed for quality of workmanship and correct application   of   repair   procedures.   The   completed   item   will   be   inspected   for   serviceable   appearance   and condition to insure against return of a sub-standard product to supply channels. a.  Vinyl  Casing  with  Ballistic  Insert.  Test  for  water  absorption  prior  to  incorporation  of  the  vinyl  casing  with ballistic  insert  into  the  outer  shell.  It  shall  be  tested  for  water  absorption  to  check  for  efficiency  of  heat sealing and for possible damage during processing. Divide units into lots of 25 or less of completed vinyl casings  with  ballistic  insert.  Select  one  of  the  units  from  the  twenty-five  and  weigh  accurately  to  the nearest 1 ounce (28.35 g). Record this weight. The assembly shall then be totally immersed in water 11 -to 7-inches (27.94 to 17.78 cm) deep and temperature of 70 ± 10°F (21.1 ± 5.5°C) for 30 minutes. The test assembly shall not be folded unless material such as netting is interlaid between folds which will permit free entry of water to all surfaces of the specimen. Upon removal at the end of the thirty minute immersion period, hang the assembly on a line or hanger and allow to drain for approximately 10 minutes. Wipe or blot dry any visable drops of water on the outside of the envelope and allow to dry another twenty minutes. At the end of 1/2 hour reweigh the assembly. If the weight is more than 1 percent over that of the original weight, leakage is indicated. If leakage is indicated, the item should be returned for the application of a new vinyl casing and all items in the lot of twenty-five should be tested and treated as outlined above. NOTE In view of the possible rejection of complete vests in the final test for water leakage  of  completed  items  which  do  not  have  new  vinyl  casings,  it  is suggested that these vests be checked 100 percent for water leakage due to the  inability  to  visibly  examine  for  possible  physical  damage  that  could occur  in  the  translucent  casing  material. b.   Complete   Vest. (1)  Dry  weight  tests.  All  vests  (100  percent  inspection)  being  returned  to  supply  channels  should  be compared against the following weights for the applicable size and stock number.
