MIL-DTL-11195H
3.6.7 Knife test. When tested as specified in 4.6.20, the enamel shall adhere tightly to and not
flake or crack from the metal surface. The film shall ribbon or curl from the metal on cutting and
the cut shall show beveled edges.
3.6.8 Water resistance. When tested as specified in 4.6.21, a film of the coating shall show no
blistering or wrinkling and no more than a slight whitening or softening immediately upon
removal from the water. Film softening shall not exceed a 2 pencil hardness difference
(see ASTM D3363) from an unexposed film with identical cure history prior to water exposure.
After 2 hours air drying the portion of the panel, that was immersed, shall be almost
indistinguishable with regard to adhesion, hardness, color, and gloss from an unexposed film
with identical cure history prior to water exposure.
3.6.9 Hydrocarbon resistance. When tested as specified in 4.6.22, a film of the coating shall
show no blistering or wrinkling when examined immediately after removal from the hydrocarbon
test fluid. When examined 2 hours after removal, there shall be no excessive softening,
whitening, or dulling. Film softening shall not exceed a 2 pencil hardness difference
(see ASTM D3363) from an unexposed film with identical cure history prior to hydrocarbon
exposure. After 24 hours drying the portion of the panel which was immersed shall be almost
indistinguishable with regard to hardness, adhesion, and general appearance from a panel
prepared at the same time but not immersed.
3.6.10 Adhesion. When tested as specified in 4.6.23, films of the enamel shall show no evidence
of removal by the adhesive tape beyond one-eighth inch on either side of the score line.
3.6.11 Salt spray resistance. When tested as specified in 4.6.24 and examined immediately after
removal from the salt spray test, films of the coating shall have a minimum rating of No. 7, based
on test method ASTM D1654, and the failure evaluation procedure for unscribed specimens,
procedure B. Upon completion of the salt spray fog test, remove the coating film and inspect the
substrate. There shall be no more than a trace of rusting, pitting, or corrosion on the panels.
3.6.12 Weather resistance. When prepared and exposed as specified in 4.6.25, films of the
enamel shall show no cracking, checking, flaking, or loss of adhesion, and no more than a trace
of rusting shall be observed when visually comparing the surface with the photographic
reference standard that illustrates minute surface corrosion, less than 0.03% rust grade No. 9, in
accordance with ASTM D610. On removal of the coating, the surface of the metal shall show no
more than a trace of rusting, pitting, or corrosion on the panels.
3.6.13 User instruction marking. All containers shall include the VOC content and VOHAP
content in g/l or lbs/gal of coating when reduced as specified with the manufacturer's
recommended HAP-free thinner. All containers shall be legibly marked or labeled with
precautionary information as follows:
CAUTION: The Surgeon General requires airline respirators to be used unless air sampling
shows exposure to be below standards. Then, either chemical cartridge respirators or airline
respirators are required. Avoid contact with skin and eyes. Use adequate ventilation. For other
