MIL-C-81084A(OS)
6.5 Definitions.
6.5.1 Humidity. The humidity is the relative humidity of the environment to which the test set is exposed,
expressed as a percent.
6.5.2 Vibration. Vibration is a sinusoidal motion defined by amplitude and frequency. The amplitude
may refer to displacement or to acceleration. The displacement is given in inches from a position of rest to
peak. The acceleration is given in multiple of gravitational acceleration. The frequency is given in cycles per
second (Hz).
6.5.3 Level C. Minimum protection designated as Level C, will be used for protection of material under
known favorable conditions. In general the following criteria determine the requirements for this level of
protection.
a.
Use or consumption of the item at the first destination
b.
Shock, vibration, and static loading during the limited transportation cycle
c.
Favorable warehouse environmental for a maximum of 18 months
d.
Effects of environmental exposure during shipment and intransit delays
e.
Stacking and supporting superimposed loads during shipment and temporary storage.
When level C is specified, it must reference applicable Public Laws (Code of Federal Regulations) or a specific
Federal or Military Specification, Standard, or Instruction.
6.5.4 Industrial packaging. Industrial packaging will be acceptable for any level of protection whenever
the technical design details of the package meet all conditions of the level of protection specified. Industrial
packaging must provide the same level of protection against physical and environmental damage as the
military package. It will be marked to the level it meets. Bulk type practices such as are used in inter- and
intraplant shipments or shipments to jobbers are not acceptable, unless they are the usual trade practices for
selected commodities.
