MIL-DTL-14072F
Adhesion Test Specimens.
Test specimens shall be prepared from actual production items or parts thereof. If size is
prohibitive, use scrap parts of the same kind and finish (from the same manufacturing lot
if possible) which have been rejected for causes other than phospating, material
composition or heat treatment. Standard test panels may be use when authorized.
4.5.3 Thickness. Except where the method of determining the thickness of
finishes is covered in applicable subsidiary specifications referenced herein, thickness
may be determined by any method acceptable to the Government. Dry paint film
thickness shall be measured at several places on each sample unit where a minimum
plating thickness would be expected due to part shape, recesses, etc.
4.5.4 Hydrogen embrittlement. Plated hardened ferrous parts shall be tested to
insure freedom from an embrittled condition. Sample units of parts shall be tested by
stressing them statically in the same way they would be stressed in service at 90 percent
of the yield strength of the base metal, for 24 hours. If one or more samples crack or
break, the entire inspection lot shall be rejected. Inspection lots rejected for failure to
pass the hydrogen embrittlement test shall not be delivered to the Government.
4.5.5 Surface condition. The finish shall be visually examined for defects listed
in Table IX.
4.5.6 Spectral reflectance. Spectral reflectance of paint films listed in Table II
are to be tested in accordance with the applicable paint specifications. Separate test
specimens may be used.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as
specified in the contract or order (see 6.2). When packaging of materiel is to be
performed by DoD or in-house contractor personnel, these personnel need to contact the
responsible packaging activity to ascertain packaging requirements. Packaging
requirements are maintained by the Inventory Control Point s packaging activities within
the Military Service or Defense Agency, or within the military services s system
commands. 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.
