18.104.22.168 Lifting and tiedown attachments. Apply the static load
specified in 3.20 for lifting attachments and 3.21 for tiedown
attachments to the attachments after the attachments are mounted on the
screening unit or section, as applicable. The direction of the applied
load shall be in the direction in which the load is normally applied.
Weld failure or permanent deformation of the attachment or of any com-
ponent of the screening unit or section shall constitute failure of this
Anchor each section of the
22.214.171.124 Tiedown attachments (d
screening unit independently, as sectionalized for rail transport, to
a flatcar using only the tiedown attachments. Use no blocking. Hump
the flatcar at a speed of 7 miles per hour against five boxcars with
their brakes set. Repeat the test with the opposite end of the section
in the direction of the five cars. Any permanent deformation or break-
age of the tiedown attachments or parts of the section shall constitute
failure of this test.
126.96.36.199 Electromagnetic interference. The preproduction model shall
be tested to determine conformance to 3.17. The supplier shall furnish
to the contracting officer the test report required by MIL-STD-461.
Disapproval of the report shall constitute failure of this test.
188.8.131.52 Production test. Operate each screening unit for a period
Of 1 hour without processing material. Test each brake system in
accordance with TTMA RP3-1-12. Any operational difficulties, breakage,
or permanent deformation shall constitute failure of this test. Operate
brakes, nonconformance to 184.108.40.206 shall constitute failure of this test.
4.7 Inspection comparison. The Government may select screening units
at any time during the contract production period and subject these
screening units to the examination specified in 4.6.1 and the tests
specified in 4.6.2 through 220.127.116.11 to determine that the quality of the
selected screening unit is equal to the quality standards established
during initial production testing. The inspection will be performed by
the Government at a site selected by the Government. Screening units
will be selected at random from those which have been accepted by the
Government and will not include the previously inspected preproduction
model and initial production screening unit(s).
4.7.1 Inspection failure. Failure of any screening unit when
inspected as specified in 4.7 maybe considered cause for refusal
