4.2 Classification of inspections. Inspection of the material covered
by this specification shall be classified as follows:
a, First article inspection (see 4.3.1)
b. Quality conformance inspection (see 4.3.2)
4.3.1 First article inspection. A first article sample of one Accessory
Set manufactured in accordance with 3.2.1 shall be subjected to the exam-
inations and tests specified in 4.5 and 4.6 at an activity designated by
the procuring agency (see 6.2). Acceptance of the sample shall be based on
no defects. Further production of the accessory setss by the supplier, prior
to approval of the sample, shall be at the supplier risk.
4.3.2 Quality conformance inspection. Each accessory set shall be sub-
jected to the examinations of 4.5 and the tests of 4.6. Only accessory sets
successfully passing this inspection shall be accepted.
4.3.3 Test conditions, Unless otherwise specified, the accessory sets
shall be subjected to quality conformance and first article inspections
under the following conditions:
a. Temperature: Room ambient 14 to 29°C (55 to 85°F)
b. Humidity: 35 to 70 percent, relative.
4,4 Special test equipment. The following items of test equipment are
required to perform the tests of 4.6:
4,4.1 Ohmmeter or bridge, direct current, 0.05 to 1.00 ohm range,
4.4.2 Wheatstone Bridge, direct current, 1.0 ohm to 2 megohm range,
0.1 percent accuracy,
4.4.3 Megohmmeter, 500 50 volts d-c test potential, capable of measuring
5.0 percent accuracy.
500 megohms or more,
etc. for testing purposes.
4.4.4 Necessary wires, plugs,
Each accessory set shall be examined in accordance with
4.5.1 and 4.5.2.
4.5.1 Solder examination. Electrical connections shall be examined prior
to soldering to determine that all connections are mechanically secure. After
soldering, the units shall be examined to determine that there are no cold
solder joints and that all excess flux and all solder spatter has been removed.
