4 . 4 . 1 Quality conformance inspection equipment. The following items of
test equipment are required to perform the quality conformance inspection tests:
Capability
Equipment
Measure 0.00 to 0.50 ohm, accuracy
a . Ohmmeter, current
plus or minus 0.01 ohm; maximum cur-
limited
rent limited to 10 milliamperes,
b . Megohmmeter
Measure 0.5 to 50 megohms with 500
plus or minus 50 volts DC potential;
full scale accuracy of 10 percent.
Leak detector
Detect gas leakage equivalent to one ten-
c.
thousandth of a cubic centimeter per
second.
Vacuum or gas type photocell with ampli-
d . Light meter
fier having joint frequency response of
not less than 200 cps; measure light in-
tensities of 2 x
candlepower with
accuracy of plus or minus 10 percent.
e . Electronic counter
Measure time interval between two events
in units as short as 500 microseconds.
f . Oscillograph
Record output from light meter specified
in "d" above; have a paper speed of 40
inches per second or faster; provide a
timing signal, in milliseconds, on paper.
Two identical and independent 60-cps
Power supplies
g.
power supplies capable of supplying
sufficient current to cause a voltage drop
of 2.0 plus or minus 0.2 volts across
a load of 0.22 plus or minus 0.01 ohm.
4.4.2 Preproduction and periodic production test eq uipment. The follow-
ing items of test equipment are required to perform the preproduction and pe-
riodic production tests. These items are in addition to selected items of quality
conformance inspection equipment and pieces of equipment recommended by
applicable specifications or standards referenced within test procedure para-
graphs.
