6.4 Definitions. Definitions of preservation, packaging, and packing
terms, including materials, processes, methods, and equipment will be found in
MIL-STD-2073-1C.
6.4.1 Levels of protection. To help determine the extent of preservation
required to protect an item against specific hazards of storage,
transportation, and handling, the Department of Defense (DOD) has established
two levels of protection whose main objectives are to provide uniform,
efficient, and economical protection to supplies and equipment. The levels of
protection are based upon the performance expected of the package. The
performance criteria are summarized as follows.
6.4.1.1 Level A. This package provides maximum protection. It is needed
to protect material under the most severe worldwide shipment, handling, and
storage conditions. Preservation and packing will be designed to protect
material against direct exposure to extremes of climate, terrain, and
operational and transportation environments, without protection other than
that provided by the pack. The conditions to be considered include, but are
not limited to, the following:
(a)
Multiple handling during transportation and in transit storage
from point of origin to final user.
(b)
Shock, vibration, and static loading during shipment
(c)
Loading on shipdeck, transfer at sea, helicopter delivery, and
offshore or over-the-beach discharge to final user.
(d)
Environmental exposure during shipment or during in transit
operations where port and warehouse facilities are limited or
nonexistent.
(e)
Outdoor storage in all climatic conditions for a minimum of 1
year.
(f)
Static loads imposed by stacking.
For packing (exterior containers), it has been determined and agreed upon by
the joint DOD packaging administrators that fiberboard and paperboard are not
an acceptable material for use under level A packing for O-CONUS shipments.
6.4.1.2 Commercial. Although not specifically defined by any Government
regulation or instruction, commercial packaging (preservation and packing) is
understood to be those practices by manufacturers and suppliers to protect and
identify material and items packaged for retail and wholesale distribution
purposes. ASTM D 3951 provides guidance in the application of commercial
packaging. It has been determined by joint DOD instructions that commercial
(also in some areas addressed as industrial packaging) should only be used or
specified when such packaging is known to satisfy the DOD needs. Such use
should be determined before a contract for supplies is awarded or within the
life cycle of the contract when substantial savings to the Government may
result. Commercial (industrial) packaging should not be specified where
multiple shipments and handling, long-term storage, or when such packaging is
known to be insufficient to meet DoD needs are anticipated or desired.
6.4.2 Multiple-trip container. The design features of a multiple trip
container are, subject to simple replacement of components, the container can
be employed for more than one round trip from initial supply source to the
consumer and return. A typical example is a demountable wooden box or crate
equipped with fasteners permitting ready assembly, disassembly, and
reassembly.
6.5 Asbestos. It is the intent of the Government to eliminate the use of
asbestos except in those cases that a suitable alternative material cannot be
used to obtain the desired results. In those cases in which components or
