5.1.2 Environmental conditions. Guidelines for
specifying environmental conditions are specified herein. Separate
requirements shall be specified for shipment, installation and operation. All
equipment shall be suitable for the environmental conditions under which it
will be installed. Environmental conditions under which the equipment is to be
fully operational shall be tailored to the specific application and use of the
equipment, and from the environmental conditions specified herein. The
equipment shall not require alignment or adjustment when fully operational.
Many MIL-STD-810 tests have equivalent IEC standards. The International
Electrotechnical Commission (IEC) standards noted herein are accepted in lieu
of MIL-STD-810 methods. Other IEC standards may be approved on a case-by-case
basis for an individual acquisition. COTS and ruggedized equipment which have
been design qualified against MIL-STD-810 (or equivalent) are acceptable if
the design qualification meets or exceeds the requirements tailored from this
document.
