MIL-DTL-53039E
Color change shall be less than 2.5 NBS units when compared to an unexposed sample of the same
batch using tristimulus color coordinates. In addition, after accelerated weathering the color
change shall remain within 2.5 NBS units of the value specified in table I (difference from nominal
values or center of color ellipse). The infrared reflectance and allowable ratio shall remain within
those limits originally specified.
3.6.13 Super Tropical Bleach (STB) resistance. When tested as specified in 4.6.26, a film of the coating
shall show no blistering, wrinkling, or film softening when examined immediately after washing with
water. Film softening shall not exceed a 2 pencil hardness difference (see ASTM D3363) from an
unexposed film with identical cure history prior to STB exposure. After drying, there shall be a
maximum color change of 2.5 NBS units when comparing a portion of the untested panel to that of the
tested area using tristimulus color coordinates. The STB composition shall be in accordance with
MIL-DTL-12468.
3.6.14 Chemical agent resistance. A film of the coating tested as specified in 4.6.27 shall desorb
a maximum of 180 micrograms of agent HD, a vesicant agent, and a maximum of 40 micrograms
of agent GD, a toxic nerve agent.
3.6.15 Weather resistance. Films of the coating tested as specified in 4.6.28 shall show no
checking, cracking, or appreciable film deterioration. There shall be no more than light chalking
(see ASTM D4214). The color shall not exceed 2.5 NBS units at 560 MJ/m2 of total UV
irradiance when compared to an unexposed sample of the same batch using tristimulus color
coordinates. The approximate equivalence of two years of total UV irradiance in Arizona is 620
MJ/m2.
3.7 User instruction marking and precaution sheet. All containers shall include the VOC content
and VOHAP content in g/l or lbs/gal of coating, and a printed precaution sheet with the
following information:
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 with adequate ventilation.
For other safety recommendations, refer to the Material Safety Data Sheets (MSDS). Keep
containers closed.
3.8 Toxicity clearance. All new chemicals and materials being added to the Army supply
system shall have a toxicity clearance. A toxicity clearance involves a toxicological evaluation
of materials prior to introduction into the Army supply system. The Army program manager
shall be responsible for identifying technically feasible materials and requesting a toxicity
clearance for use of that material within their program (see 6.4.4).
3.9 MSDS. The manufacturer shall comply with the requirements set forth by the Hazardous
Communication Standard, 29 CFR 1910.1200. A MSDS shall be prepared for the coating in
accordance with FED-STD-313 and forwarded to the qualifying activity (see 6.4.2). The MSDS
for the material covered by this specification shall be included with each shipment, and
submitted to pertinent Government agencies as stated in FED-STD-313.
3.9.1 Safety Data Sheets (SDSs). A Safety Data Sheets (SDSs) shall be phased into the system
by the following deadline of June 1, 2015 and after June 1, 2016 the Material Safety Data Sheets
