1/ Number of samples shall be in multiples of 2. The acquiring
activity shall specify the number of samples and the inspection
sequence each unit shall be subjected to for lots in excess of 300
units (see 6.2g).
4.5 Inspection conditions. Unless otherwise specified, all inspections shall
be performed under the following conditions:
a. Room temperature. Room ambient of 77 ± 18° F indicated.
b. Test temperature. All parts of the test item shall be stabilized at the
specified temperature ± 5° F indicated prior to conducting any tests. Unless
otherwise specified, temperature stabilization will have been attained when
the indicated temperature of the surface of the largest mass of the test item
does not change more than ± 5° F per hour.
4.6 Methods of inspection.
4.6.1 Actuator inspection. The actuator shall be inspected as follows.
18.104.22.168 First article and quality conformance inspections.
a. Each actuator shall be thoroughly examined to determine conformance to
all of the requirements specified herein.
b. Each actuator shall be inspected to ensure that it has been properly
assembled and that the workmanship is as specified (see 3.3.17).
c. The actuator shall be examined to ascertain that the packaging conforms
to contract requirements (see section 5 and 6.2. lc).
4.6.2 Functional tests. The actuator shall be subjected to the following
checks. All checks shall be performed with the actuator mounted as intended
by the applicable drawing.
22.214.171.124 Operational check. The actuator shall be subjected to 50 cycles of
operation. Each cycle shall consist of cocking and then energizing the
actuator with 28 VDC.
126.96.36.199 Plunger force. The actuator plunger thrust force shall meet the
requirement of 3.3.11 when measured after the release of the actuator plunger.
