3、s specification is approved for use by all Departments and Agencies of the Department of Defense. 1. SCOPE 1.1 Scope. This specification covers four types of air pollution regulated ship and structure coatings that comply with the National Emission Standards for Hazardous Air Pollutants (NESHAP) for
4、 shipbuilding for state and federal regulations. There are nine classes of coating systems. There are four grades of coating systems based on temperature of application and cure. In addition to tanks, all paint systems qualified to this specification are suitable for use on any ship structures, inte
5、rior or exterior, for corrosion control. Except for trace levels, all types are free of lead, chromium, cadmium, and asbestos (see 3.2.3). All types have levels of hazardous air pollutants (HAPs) that do not exceed applicable NESHAP levels (see 3.2.2.2). Dry Type V, VI, VII, and VIII coating residue
6、s and debris are non-hazardous waste under U.S. Environmental Protection Agency (USEPA) regulations in effect on the date of this specification. Type VII coating will not have any solvent added to either the base resin component or the hardener component. 1.2 Classification. 1.2.1 Types. The types o
7、f coating systems are as follows: Type V - A coating system having a maximum volatile organic compound (VOC) content of 340 grams per liter (2.83 pounds per gallon) of coating. HAPs in the solvent will not exceed VOC levels (see 3.2.2.3). Use of pigments that are hazardous to workers or create hazar
8、dous waste is restricted to trace levels (see 3.2.3.1). May be used in any air quality management district regulating VOC. Dry coating is not a hazardous waste under USEPA regulations. Type VI - A coating system having a maximum VOC of 250 grams per liter (2.08 pounds per gallon) of coating. HAPs in
9、 the solvent will not exceed VOC levels (see 3.2.2.3). Use of pigments that are hazardous to workers or create hazardous waste is restricted (see 3.2.3.1). Dry coating is not a hazardous waste under USEPA regulations. Type VII - A coating system having a maximum VOC of 150 grams per liter (1.25 poun
10、ds per gallon) of coating. HAPs in the solvent will not exceed VOC levels (see 3.2.2.3). Use of pigments that are hazardous to workers or create hazardous waste is restricted to trace levels (see 3.2.3.1). Dry coating is not a hazardous waste under USEPA regulations. Coatings proposed for qualificat
11、ion testing to this type have no solvent added to either the base resin component or the hardener component. Type VIII - Non-metallic functional powder coating system for severe marine service having a maximum VOC of 75 grams of solvent per 4.54 kilograms (0.17 pounds of solvent per 10 pounds) of po
12、wder. Type VIIIa - Functional powder coating system with two coats which may contain zinc for severe marine service with a maximum VOC of 75 grams of solvent per 4.54 kilograms (0.17 pounds of solvent per 10 pounds) of powder.

The classes of coating systems are as follows: Class 5 - A coating system for use in fuel tanks, seawater ballasted fuel tanks, seawater tanks, bilges, and other ship structures, interior and exterior. Class 5 coatings are not for use in tanks t
14、hat may be used for fresh or potable water. Class 6 - Class 6 coatings no longer used. Class 7- A coating system for use in dedicated seawater ballast tanks. Class 6 coatings are not for use in tanks that may be used for freshwater, potable water, fuels, or other hydrocarbons. Class 8 - Class 8 no l
15、oner used. Class 9 - A coating system for use in dedicated potable or freshwater tanks. Class 7 coatings are not for use in tanks that may be used for seawater, fuels, or other hydrocarbons. Class 10 - Class 10 coatings no longer used. Class 11 - A coating system for use in dedicated boiler feedwate
16、r (pure water) tanks. Class 8 coatings may not be used for seawater, potable water, freshwater, fuels, or other hydrocarbons. Class 12 - Class 12 coatings no longer used. Class 13 - A coating system for use in dedicated chemical holding (ship sewage/waste) tanks (CHT tanks). Class 9 coatings may not
17、 be used for seawater, potable water, freshwater, fuels, or other hydrocarbons. Class 14 - Class 14 coatings no longer used Class 15a - A coating system intended as a repair or touch-up coating for use over oily surfaces that are prepared to bare metal surfaces where paint has been removed to the ba
18、re metal substrate. Class 15b - A coating system intended as a repair or touch-up coating for use over wet surfaces that are prepared to bare metal surfaces where the paint has been removed to the bare metal substrate. Class 15c - A coating system intended as a repair or touch-up coating for applica
19、tion and cure under (salt) water. Class 16 - Class 16 coatings are no longer used. High wear resistant coatings are available in MIL-PRF-32171 Class 17 - A coating system intended for use on properly cleaned and prepared bilge surfaces. Class 18 - A single-coat coating system. Class 19- A coating sy
20、stem intended for use on well deck overhead areas of Landing Craft Air Cushion (LCAC) capable ships. 1.2.3 Grades. The grades of coating systems are as follows: Grade A - A coating system which can be applied down to a temperature of 32 F (0 C) and cured down to a temperature of 25 F (-4 C). Grade B
21、 - A coating system which is to be applied and cured at temperatures above 32 F (0 C) up to 49 F (10 C). Grade C - A coating system which is to be applied and cured at or above a temperature above 50 F (11 C). Grade D - Powder coatings cured at a high temperature in accordance with manufacturers ins
