|  4.4.3.3 Torpedo ready non-operating, ready, or operating. . The tor-
2g acceleration in the directions specified
pedo shall be subject to 15g
in 4.4.3.2 as appropriate for a time period of not less than 0.2 sec.
4.4.3.3.1 Load. - Load applications for aircraft carried torpedoes my
require special consideration. In l uch cases load applications shall con-
form to MIL-A-8591.
4.4.4 Temperature test procedures. - Except for the torpedo operating,
all the temperature tests l hall be made with all access covers removed,
and such that condensation from the test chamber cannot drip Into these
openings. Prior to torpedo checkout, wiping or air-hose drying may be
Performed but no drying by heating or baking shall be done. (For the tor-
pedo operating, access covers shall be replaced)
4.4.4.1 Torpedo non-operating.
4,4.4.1.1 Temperature and humidity cycling. . The total test is made
up of' two 14-day temperature and humidity cycles. The term "chamber tem-
perature" used In this tent is the temperature of the air immediately
surrounding the torpedo. Chamber temperature may be changed (1) by vary-
ing the temperature of a single chamber, or (2) by moving the torpedo
from one constant-temperature chamber to another. The fluctuation from
all specified temperatures shall not exceed
following test
sequence is based on a start at 0800 Monday. Regardless of the day and
time the test is initiated, there shall be no deviation from the test
sequence as prescribed.
4.4.4.1.1.1 At 0800 Monday place the torpedo in a chamber maintained
at -65F . for at least two hours (humidity not controlled).
4.4.4.1.1.2 At 1600 Monday the chamber temperature shall be changed
and 95 percent himidity. The chamber temperature must reach
to
/160F. and 95 percent humidity not later than 1800.
4.4.4.1.1.3 The torpedo shall be held under these conditions until
0800 Tuesday, at which time the temperature decrease shall begin. The rate
of decrease of chamber temperature shall be equal to or greater than 36%.
per hour for at least 2 1/2 hours. Thus, at 1030, the temperature of the
air surrounding the torpedo must be
or lower. The chamber tem-
perature must reach -65F. no later than 1400, and this temperature shall
be hold until 1600.
4.4.4.1.1.4 At 1600 Tuesday the chamber temperature shall be changed
and 95 percent humidity as rapidly as practicable (not later
to
than 1800) and held until 0800 Wednesday.
