3. REQUIREMENTS
3.1 Materials.
3.1.1 Boxes. Material for all boxes shall conform to ASTM D4727/D4727M, type CF, class WR. Boxes of type I, type III (except for box sizes requiring a variety DW, material grade V13c on figure 4), and type IV packs shall be a variety SW, material grade V3c. Type II packs shall
be a variety SW, material grade W5c.
3.1.2 Cushioning. Cushioning material for type I, III, and IV packs shall meet the first article requirements of MIL-PRF-26514 except that use of the color coding requirement shall be optional and the material shall conform to type I, class 2, grade C. Cushioning for type II, style D packs shall conform to type III, class 2, grade A, B, or C.
3.1.2.1 Convolutions. All convolutions for cushioning shall have dimensions and tolerances as specified on figure 6. Each convoluted cushioning component shall have peaks with a uniform height of K.
3.1.2.2 Laminations. Deep or long body cushions (such as the star shaped die-cut bodies) shall be made from a whole piece or shall be built up to the specified dimension by means of laminations. All lamination pads used in a cushioning system shall be composed of material having the same cushioning characteristics. The minimum nominal thickness of lamination pads shall be 2 inches (50 mm). Thicker lamination pads may be used to minimize the number of laminations. Convoluted cushioning shall be made from a whole piece or shall be built up to the specified thickness by lamination of a nominal 2 inches (50 mm) or thicker pad, provided that
the convoluted section shall be integral with a minimum 1 inch (25 mm) thick base section (see figure 6). Type II convoluted cushioning shall be cut from a single piece of foam and shall have a minimum base thickness of 1/2 inch (13 mm).
3.1.2.3 Bonding of laminations. As a minimum, laminations shall be spot bonded with a maximum of 50% coverage (see 3.2.5), using adhesive specified in 3.1.5 to sufficiently to maintain true alignment and integrity of the built-up cushioning configuration. The built-up body of type I packs may be assembled without bonding the laminations together. On type III, style G, apply adhesive to only the top half of the end and side pieces. On type IV, style B only, bond the top cushion to the container lid.
3.1.2.4 Anti-static property. The cushioning for type II packs shall be uniformly impregnated with an electrostatic agent. For style D the static dissipative material shall conform to all
