44 Description
Storage
Temperature: -50ûC to +70ûC
Relative Humidity: 5% to 95% (non-condensing)
Temperature cycling
The installed LMI, RMI, and LMX circuit packs withstand and operate
normally after three temperature cycles according to IEC 69-2-14, Test
Nb. The following conditions apply:
0ûC to 60ûC in 3 minutes for each cycle
Thermal shock
The installed MCR packs withstand and operate normally after 5 cycles of
thermal shock. The following conditions apply:
-50ûC to ambient temperature in 3 minutes and +70ûC to ambient in 3
minutes constitutes one cycle.
Duration at -50ûC and at +70ûC shall be 60 minutes.
Duration at ambient temperature shall be 60 minutes.
Shipping and seismic considerations
Mechanical shock - packaged
The packaged LMI, RMI, and LMX circuit packs are not damaged after
being dropped from a height of 30 inches on one corner, on three edges,
and on all faces, according to NTSA, project 1A.
Mechanical shock - unpackaged (servicing)
The LMI, RMI, and LMX circuit packs retain full functionality after being
dropped, as described in TR-EOP-000063(NEBS) under the following
conditions:
From a 30û tilt onto all faces and corners
Mechanical shock - transportation bounce
The packaged LMI, RMI, and LMX circuit packs retain full functionality
after bounce testing according to IEC 68-2-29, Test Eb under the following
conditions:
Constant acceleration of 1.2 g
Duration of 30 minutes per surface
