4.4.1.3.2 Disposition of sample units. Sample units which have passed all the group B inspection
may be delivered on the contract or purchase order, if the lot is accepted.
4.4.2 Test equipment and inspection facilities. Test equipment and inspections facilities shall be of
sufficient accuracy, reliability, and quantity to permit performance of the required inspection to the
satisfaction of the Government.
4.5 Method of examination and test.
4.5.1 Visual and mechanical examination (see 3.1, 3.3 through 3.4 incl., 3.13 and 3.14). Lines shall
be examined to verify that the material, design, construction, physical dimensions, marking, and
workmanship are in accordance with the applicable requirements.
4.5.2 Attenuation (see 3.5). The attenuation of the lines shall be measured over the specified
frequency range (see 3.1). The test equipment shall be capable of providing a continuous measurement
of attenuation over the required frequency ranges. A means shall be provided for producing a permanent
record of the line attenuation versus frequency. If attenuation is not directly measured; that is, if return
loss is measured and attenuation is calculated from that measurement, the permanent record shall
indicate the worst case attenuation numerically for each frequency band and shall provide the calculation
used to obtain the calculated attenuation. The length of the test sample shall be 100 feet (minimum).
4.5.3 VSW R (see 3.6). The VSW R of the lines shall be measured over the specified frequency range
(see 3.1). The test equipment(s) shall be capable of providing a continuous measurement of VSW R over
the required frequency ranges. A means shall be provided for producing a permanent record of the line
VSW R versus frequency. If VSW R is not directly measured; that is, if return loss is measured and VSW R
is calculated from that measurement, the permanent record shall indicate the worst case VSW R
numerically for each frequency band and shall provide the calculation used to obtain the calculated
VSW R. The length of the test sample shall be 100 feet (minimum).
