    40、oduction seam sealing system evaluation. Prior to seam sealingany patient wrap end-items, the basic polyethylene material shall be evaluatedto assure proper seam sealing machine settings, tape alignment, appearance, andsealability. An individual evaluation shall be conducted per seam sealingmachine

    41、at the beginning of each day that patient wrap end-items are be to seamsealed. The following constitutes this evaluation:(1) Seam sealing procedure - Prepare a rectangular specimen of poly-ethylene material at minimum size 8 x 24 inch (any direction). Single needlesew, using either 301 lock-stitch o

    42、r 401 chainstitch using size E thread at 8-12stitches per inch, down the middle of the 8 inch material width for the entire24 inch length. Operate seam sealing machine according to tape manufacturersrecommended settings and apply middle of seam sealing tape over sewn seam on thedull green side of ma

    43、terial. Observe polyethylene material under taped sectionand along tape sides by through lighting. There shall be no sign of melting,burning, delamination, puckering, or any visible degradation of any kind to thematerial. Further, the tape shall be crystal clear and be free from any edgepuckering th

    44、roughout the entire length of the specimen.(2) Tape alignment - At random, fold a section of seam sealed materialacross the width of tape such that a crease mark is visible when unfolded.Observe that the tape edges remain clear with no sign of delamination at thispoint. Note that any unclear tape ar

    45、eas signify either delamination or pointsin which the heat nozzle of the sealing machine are in misalignment with thetape.(3) Hydrostatic resistance - To determine proper seal, a randomlyselected taped section shall withstand a hydrostatic resistance of 50 cm for 3minutes with no sign of moisture pe

    46、netration through the seam when tested inaccordance with TM 5514. As an alternate, a commercially available hydrostaticmachine with a 4-1/2 inch head may be utilized. The taped specimen shall main-tain a hydrostatic pressure of 0.75 psi for 3 minutes with no sign of moisturepenetration. In either ca

    47、se, the taped material side shall be against thehydrostatic head. In case of dispute at the time of testing, T145514 shall beused.(4) ReDortin - If previous taped material observation, tape alignment,and hydrostatic resistance results meet requirements, then record sealingmachine settings (temperatu

    48、re, pressure, and speed) and date onto taped materialspecimen with indelible ink, and continue with daily producion utilizing thesesettings. Repeat all tests and reporting procedure for each day of production.Retain all taped specimens until acceptance of end-items has been finalized. . .6.-Provided
