5.2.1 Defects. The cover shall be uniform in quality and shall be free from irregularities or defects which
affect performance, reliability, or durability. Commercial defects: cuts, cracks, holes, dirt gels, or other
defects which may impair its utility or appearance; not uniform in color, texture and finish; variation in
film thickness; any foreign material; label missing or not as specified; measurement of item not as
specified; not heat sealed across one end; excess material not trimmed evenly. The cotton cord not of
color CG 483; not one piece; any cut; chafed or damaged; core missing; kinks, broken or loose ends;
unevenly braided resulting in open places, breaks in continuity of braid or soft spots; finish gummy or

5.4 End Item Performance Testing. The end item shall be tested for label adhesion, seam strength,
crease strength, and leakage.
5.4.1 Ink adhesion label test. The ink adhesion shall be determined in accordance with
ASTM-F-1842 except that the test shall be performed on the label of a finished cover. The test area of
the label shall be visually examined for legibility.
5.4.2 Seam and crease strength tests. Strength of the heat sealed seam area and the creased area shall
be determined in accordance with method ASTM D 882. The specimens shall be 1 inch in width and
shall be cut from a finished cover with the seam or crease across the short dimension and equidistant
from the ends. The gage marks need not be applied and the elongation need not be measured. The initial
separation between the grips of the apparatus shall be 2 inches and the specimen shall be placed in grips
with the seam or crease equidistant between the grips. The strength of the seam or crease reported in
pounds to the nearest 0.1 pound, shall be the average of 5 determinations per sample unit. The film
strength shall be determined by the same method used to determine the seam strength except that
specimens shall be cut from the unseamed and uncreased section of the cover with the long dimension
parallel to the long dimension of the cover and all reference to the seam or crease shall not apply. The
strength of the film, reported in pounds to the nearest 0.1 pound, shall be the average of 5.0
determinations per sample unit.
5.4.3 Leakage test. The cover shall be marked 5 inches from the inside of the seam and filled with water
