3.4.5.1 Type I heat resistance. When prepared in accordance with 4.5.11.1.1 and tested in accordance with
4.5.11.1.2, films of paint shall show no cracking, blistering, flaking, or peeling. When the knife test (see 4.5.11.1.2)
is done, the paint shall adhere tightly to the metal.
3.4.5.2 Type II heat resistance. The heat resistance test of 4.5.11.1.2 for Type II powder coatings shall be terminated and results reported only for panels heated in sequence up to 372 °C (700 °F). When the knife test (see
4.5.11.1.2) is done, the paint shall adhere tightly to the metal.
3.4.6 Salt spray resistance. When prepared and tested in accordance with 4.5.12, films of the paint examined immediately after removal from the test shall show no more than a trace of rusting and no more than 5 scattered blisters, none of which is larger than 1 mm in diameter. Some dulling or staining unaccompanied by red rusting shall be permitted. On removal of the paint from the panels tested as specified in 4.5.12.2, the surface of the steel shall show no more than a trace of rusting, pitting, or corrosion (ASTM D610, Figure 1, No. 9).
3.4.7 Water resistance. When prepared and tested in accordance with 4.5.13, a film of paint shall show no wrinkling or blistering immediately upon removal of the panel from the water. The paint shall not be significantly affected when examined 2 hours after removal, and after 24 hours air drying, the portion of the paint which was immersed shall show no more than an insignificant whiting or dulling in comparison to the portion that was not immersed.
3.4.8 Hydrocarbon fluid resistance. When prepared and tested in accordance with 4.5.14, a film of paint shall show no wrinkling or blistering immediately after removal from the fluid. After 24 hours air drying, the portion of the panel which was immersed shall be almost indistinguishable with regard to hardness and adhesion from a panel that was prepared by at the same time but not immersed.
3.4.9 Toxins, carcinogens, and reproductive stressors. All paints proposed for qualification shall be referred to the Navy Environmental Health Center (NEHC) for an administrative Health Hazard Assessment (HHA) relative to human health hazards (see 4.5.15).
3.4.10 Recoat. When tested in accordance with 4.5.11.1.4 fully cured Type II powder coatings shall be compatible with Type I liquid coating. When recoated with Type I liquid paint, there shall be no blistering, wrinkling or lifting of either coating.
3.5 Material safety data sheet. The contractor shall provide to the qualifying agency a completed material safety data sheet (MSDS) in accordance with ANSI Z129.1 or FED-STD-313 (see 6.2).
3.6 Directions for mixing and applying. The manufacturer shall provide written directions for mixing and applying the paint on each container to the qualifying agency. These directions shall cover both small (1 L or 4 L [1 quart
{qt} or 1 gallon {gal}]) and field (19 L [5 gal]) procedures, and shall specifically state the differences, if any, between the two. These directions shall be in the format specified in ASTM F718 and shall include, as a minimum,
information on the upper and lower temperature and humidity limits for application, coverage per L (gal), and safety precautions. Type II powders shall be furnished in unit containers consistent with the powder coating
manufacturing process.
3.7 Batch specific VOC certification. Manufacturer shall prepare label instruction in accordance with 29 CFR
1910. Each container shall be affixed with a hazardous chemical warning label in accordance with 29 CFR
1910.1200. To comply with the Environmental Protection Agency (EPA) National Emission Standards for Hazardous Air Pollutants (NESHAP) requirements for shipbuilding and ship repair, the two following statements shall appear on each paint can label:
a. Certification that the paint in the container meets the NESHAP requirements for shipbuilding and ship repair.
b. Statement of the ratio of volatile content to solids expressed as grams of volatile organic hazardous air pollutants (VOHAP) per liter of solids.
3.8 Recovered materials. The offeror/contractor is encouraged to use recovered materials to the maximum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR).
