Unless otherwise specified (see 6.2), box closure shall be as specified in the
applicable box specification or appendix thereto except that box closure for
ASTM D 5118 shall be in accordance with ASTM D 1974. When the gross weight is
greater than 20 pounds, unit and intermediate containers shall conform to the

cushioned, as required, to prevent damage to the item as specified in MIL-STD-

result. Cushioning materials which have not been chemically refined for
noncorrosiveness shall only be used when contained in a sealed waterproof
barrier in accordance with PPP-B-l055. Cushioning materials used within the
unit pack shall conform to any of, or combination of, the following
