4.4 Testing of the end item. The finished heat sealed sheets shall be tested for strength of seams
(see 4.41). In lieu of the actual end items, sample units for testing shall be prepared by cutting
one linear yard in half in warp direction and by heat sealing the two pieces together warpwise
along their two uncut edges, using the same apparatus, temperature and sealing time as would be
used during the actual production of the sheets. Three such sample units shall be prepared for
each lot. For each sample unit, a different roll of laminated fabric shall be used and the roll
number shall be marked on the sample unit. The lot shall be unacceptable if one or more sample
units fail to meet the requirement for strength of seam.
4.4.1 Testing of seams. The seam strength shall be tested in accordance with ASTM-D 5034
(G-E or G-T) with the following modifications:
The test specimen shall be a rectangle of cloth measuring 4 inches by a minimum of 6
inches, with the welded seam in the middle of the rectangular strip. The short dimension of the
specimen shall be parallel to the welded seam. Five (5), specimens prepared as indicated above
shall be tested from each unit of product and the average shall be reported as the strength of seam
of a sample unit. NOTE: If the seam strength is not measurable because the base fabric itself is
breaking while the heat sealed seams seam remains intact, the seam strength shall be considered
acceptable, provided the base fabric itself meets the break strength in A-A-55308.
