3. REQUIREMENTS
3.1 Qualification. The coating furnished under this specification shall be a product authorized
by the qualifying activity for listing in the Qualified Products Database (QPD) before contract
award (see 4.2 and 6.4). Any change in the formulation or processing of a qualified product shall
necessitate its requalification. The material supplied under contract shall be identical, within
manufacturing tolerances, to the product receiving qualification.
3.2 Materials. The materials used in the coating shall be as specified herein. Materials not
specified shall be selected by the contractor and shall be subject to all provisions of this
specification.
3.3 Color and reflectance. All camouflage colors listed in table I shall impart to the substrate the
required spectral reflectance properties in the visible (400-700 nanometers) and near infrared (700-
900 nanometers) spectrums. Some camouflage colors shall have numerical requirements and some
shall have visual matches for chromaticity as listed in table I. Interior Aircraft Black, 37031,
Aircraft Gray, 36300, Dark Sandstone, 33510 and Tan 33531 shall visually match the appropriate
chips from FED-STD-595. Aircraft Green, 34031 and Green 808, 34102 shall visually match color
chips furnished by U.S. Army Research Laboratory (ARL), ATTN: RDRL-WMM-C, Organic
Coatings Team, Building 4600, Deer Creek Loop, Aberdeen Proving Ground (APG), MD 21005-
5066. All other colors listed in 1.2.2 shall visually match the appropriate chip from FED-STD-595.
The colors listed in table I shall meet the infrared reflectance requirements of table I when tested as
outlined in 4.6.2 and 4.6.13. The color Dark Green, 34082 and Green 383, 34094 shall meet the
spectral reflectance limits specified in table III. The color IRR Foliage Green 504, 34160 shall
meet the spectral reflectance limits specified in table IV. The color Green 808, 34102 shall meet
the spectral reflectance limits in table V. Colors not listed in table I are only visual matches (VM)
to the required color chip, as specified in FED-STD-595.
