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. When a first article inspection is required, it shall be performed on
one complete penetrometer assembly. This inspection shall include the examination of 4.4 and
the testing of 4.5.
4.3 Conformance inspection. Conformance inspection shall include the examination of 4.4 and
the testing of 4.5.
4.4 Examination. Each penetrometer shall be examined for compliance with the requirements
specified in 3.2 through 3.8. Any redesign or modification to comply with specified
requirements, or any redesign or modification necessary following failure to meet the specified
requirements, shall receive particular attention for adequacy and suitability. This element of
inspection shall encompass all examinations of performance and dimensional requirements.
Non-compliance with any specified requirement, or the presence of one or more defects
preventing or lessening maximum efficiency shall constitute cause for rejection.
4.5 Testing. Force in 10 PSI increments up to 150 PSI shall be applied to the top of the penetro-
meter. Force may be applied by any of the load machines commonly used in laboratory work or
by using dead weights with the penetrometer resting securely on an unyielding impenetrable
surface. After each increment, a visual check of the indicator shall be made and recorded. The
indicator shall display an accuracy of ± 2.5 PSI up to 50 PSI and ± 3.5 PSI beyond the 50 PSI
range and shall return to 0 PSI with the force removed. Failure to display the aforementioned
accuracy or failure of the indicator to return to 0 PSI, shall constitute failure of this test.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When actual packaging of materiel is to be performed by DOD
personnel, these personnel need to contact the responsible packaging activity to ascertain
requisite packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activity within the Military Department or Defense Agency, or within
the Military Department's System Command. Packaging data retrieval is available from the
managing Military Department's or Defense Agency's automated packaging files, CD-ROM
products, or by contacting the responsible packaging activity.
