4.6.7 MALF signal test
4.6.7.1 Apply the logical one type-A and type-A1 input signals
(items 3.1 and 3.2 of table. I) to P1-35 and P1-37, respectively, and a
momentary logical zero type -A signal to P1-14. Measure the output at
P1-32 to determine compliance with 3.3.1.6.1. Then apply a momentary
logical zero type-A signal to P1 -33 and, again, measure the output at
P1-32 to determine compliance with 3.3.1.6.1.
4.6.7.2 Apply a logical zero type-A signal momentarily to P1-14.
Measure the output at P1-32 to determine compliance with 3.3.1.6.2.
Then apply type-A and type-Al signals as specified on figure 5 to P1-35
and P1-37, respectively. Measure the output at P1-32 to determine
compliance with 3.3.1.6.2.
4.6.8 Continuity test, With no power or signals applied,
measure the resistance between pins P1-7 and P1-12, P1-11 and P1 -30,
P1-29 and P1-31, and P1-29 and P1-13 to determine compliance with
3.3.1.7.
4.6.9 Environmental tests.
4.6.9.1 Temperature. The test apparatus shall be in accordance
with the applicabl test facilities provisions of MIL-F- 13926 except that
the assembly may be mounted on the inside surface of the test chamber.
Perform this test in accordance with Procedure I of MIL-F-13926, with
conditions C (-40F) and E (+125F), and with the rate of temperature
change during cycling not greater than 8F per minute. At each of the
specified operating temperatures, perform the tests of 4. 6.2 through
4.6.8 to determine compliance with 3.3.2.1 and 3.3.2.2.
4.6.9.2 Vibration. Perform this test utilizing the apparatus
specified in Method 514.1 of MIL-STD-810 and in accordance with Part 1
of Procedure 1 therein, except that the vibratory conditions of 3.3.2.3
shall apply. Following vibration exposure, examine the assembly for
structural failures, loose hardware, wire breakage, and abrasion.
Perform the tests of 4.6.2 through 4.6.8 to determine compliance
with 3.3.2.3
