4.4 Conformance inspection. The contracting officer shall require that an appropriate sprayed
sample from each production lot (see 4.4.1) be forwarded to ARL, ATTN: RDRL-WMM-C,
Organic Coatings Team, Building 4600, Deer Creek Loop, APG, MD 21005-5066.
Conformance inspection shall consist of testing spectral reflectance characteristics to include
color, STB resistance, and gloss at 60 and 85 degrees. There shall be no failures (see 6.5).
4.4.1 Lot and batch formation. For purposes of conformance inspection, a lot shall consist of all
coatings of the same type, composition and color, from a single uniform batch, produced and
offered for delivery at one time (see 6.4.1). A batch shall consist of all coating material (in U.S.
gallons) manufactured during one continuous operation and forming part of one contract or order
for delivery (see 6.4.1). When required, the manufacturer shall furnish with each lot and/or
batch a certified test report showing that the material has passed the conformance inspection, and
that there has been no formulation or process change from that which resulted in the production
of the qualification inspection sample. The addition of any substance to a batch shall constitute a
new lot.
4.5 Inspection conditions. Unless otherwise specified, all inspections shall be performed in
accordance with ASTM D3924. Also, unless otherwise stated in the test method or paragraph,
room temperature shall be 73 ± 4 °F (23 ± 2 °C) and a 40 - 70 percent relative humidity.
4.6 Test methods.
4.6.1 Testing. Except as otherwise specified herein, the routine testing and referee testing shall
be conducted in accordance with ASTM D3924. A dry film thickness of 2 ± 0.2 mils (50 ± 5
microns) shall be used whenever film thickness is requested in any test, unless otherwise
required by the test. Failure of any test result to fall within the ranges specified in section 3 shall
constitute failure of the applicable test.
4.6.1.1 Test procedures. Tests shall be conducted in accordance with table X. The right is
reserved to make any additional tests deemed necessary to determine that the coating
meets the requirements of this specification.
4.6.1.2 Test panels. Unless otherwise specified, metal panels used for test purposes shall be of the
following types:
