(d) At 1600 Tuesday the chamber temperature shall be changed to +160
degrees F and 95 +3 -0 percent humidity as rapidly as practicable (not
later than 1800) and held until 0800 Wednesday.
(e) On Wednesday, Thursday, and Friday the operations performed on
Tuesday shall be repeated.
(f) The chamber temperature shall be raised to +160 degrees F and
95 percent humidity on Friday evening and shall be so maintained until
0800 Monday.
(g) At 0800 Monday the sequence of operations described above for
Tuesday of the first week shall be followed and shall be repeated daily
until Friday of the second week.
(h) On Friday, the chamber temperature shall be reduced to -65 de-
grees F and this temperature shall be maintained until 0800 Monday of the
third week. The cycle will be complete on 0800 Monday.
4.5.4.8.1 The above sequence of temperature and humidity conditions
will constitute one cycle. Two such cycles shall be applied. The second
cycle shall be completed at 0800 Monday of the fifth week. At that time,
the test specimen shall be allowed to return to room temperature. Without
drying, wiping, or baking, the test specimen shall meet the requirements
of 4.5.3.2 (Insulation resistance) and 4.5.3.3 (Continuity).
4.5.4.9 Tropical environment. For this test, the cable connector shall
be mated to Torpedo Control Cable Mk 7 Mod O. The coupled unit shall be
mounted in the test chamber wall or suitably protected so as to prevent
exposing the in-line connector face and the tube side of the cable con-
nector.
(a) The test specimen shall be placed in a mold chamber in which a
temperature of 86 degrees F 5 degrees F and a relative humidity of 90
percent 5 percent is maintained. The test specimen, while so housed,
shall be sprayed with a suspension of mixed spores. The test specimen
shall be maintained in this condition for a period of 28 days. At the
end of this period, the test specimen shall be allowed to return to room
temperature, and it shall be examined for evidence of being nutrient to
fungi. If the test specimen shows susceptibility to fungi, colored
photographs shall be taken.
(b) At least five groups of fungi shall be used in the test specimen
inoculation. Five such groups are listed in MIL-T-18404 and one type of
fungus from each group shall be used. In preparing the spore suspension,
distilled water (having a ph value between 5.8 and 7.2 at 77 degrees F)
shall be prepared by sterilization in convenient containers (approximately
