4. VERIFICATION

4.1 Classification of inspections. The inspection requirements specified herein are

classified as follows:

a. First article inspection (see 4.2)

b. Conformance inspection. (see 4.3)

4.2 First article inspection. First article inspection shall be performed on a specified

number of scanners when a first article inspection is required (see 3.1). This inspection shall

include the examination of paragraph 4.4, and the tests of 4.5.1.2 and 4.5.3, 4.5.5, and 4.5.6

included herein; and the tests of MIL-PRF-49166 herein referred to in paragraphs 4.5.1.4, 4.5.2,

4.5.4, and 4.6 referenced herein.

4.3 Conformance inspection.

4.3.1 Tests. Perform the examination of 4.4 and the tests of 4.5 et al.

4.4 Examination. Each mechanical scanner shall be examined for compliance with the

requirements specified in 3.2 through 3.5. Any redesign or modification of the contractor's

standard product to comply with specified requirements, or any necessary redesign or

modification following failure to meet the specified requirements shall receive particular attention

for adequacy and suitability. This element of inspection shall encompass all visual examinations

and dimensional measurements. Noncompliance with any specified requirements or presence of

one or more defects preventing or lessening maximum efficiency shall constitute cause for

rejection.

4.5 Methods of inspection. Tests shall be performed utilizing the Scan-Interlace, PL-

1403/UA, with the MX9872(V)2/UA with a scan angle of 6.1, � 0.3 degrees at the 30.0, � 0.5 Hz

scan rate. Otherwise, the contractor/supplier may use his own test methods, measuring devices,

tools, fixtures, and other equipment during the conduct of verification testing. This specification

cites no test requirements as long as all the performance requirements per Section 3 are fully

verified as being met.

4.5. 1 Scan angle and frequency.

4.5.1.1 Variable scan frequency. Not applicable.

4.5.1.2 Specific scan frequency (30 Hz). The MX-9872(V)2/UA shall be connected to the

Scan-Interlace, PL-1403/UA, and mounted to a suitable fixture. Power shall be applied and the

output of the tachometer (Scan-Interlace, PL-1403/UA) shall be monitored with a calibrated

frequency counter. The Output of the Scan-Interlace, PL-1403/UA, shall be adjusted to obtain

the specific scan frequency. Failure to meet the requirements of 3.5.1.2 shall constitute failure of

this test.
