The TMC capacitors will withstand 6 hours of
vibration testing, 2 hours in each of three mutual-
ly perpendicular planes. The frequency will vary
from 10 Hz to 55 Hz and back to 10 Hz over a
one minute period, continuously during each 2
hour test, with a total excursion of 1.5 mm.
During the last 30 minutes of vibration, in each
direction, electrical tests shall be conducted.
