specified in 4.9.2. The jig shall be designed so that removal of the tank test structure may be
accomplished with a minimum effort.
4.3 First article inspection. When a first article sample is required (see 3.1), samples shall
be inspected as specified in table I. First article samples shall be selected as follows:
Three full size tanks complete with necessary fittings.
Three 12 by 12 in. specimens of composite tank construction.
One specimen of inner layer ply, without barrier, approximately 900 square inches (in2)
in area, including seam.
One specimen of 6 by 6 in. inner layer ply, without barrier.
Three permeability specimens in accordance with 4.8.3.2.
