PERFORMANCE SPECIFICATION

COATING SYSTEMS FOR SHIP STRUCTURES

This specification is approved for use by the Naval Sea Systems Command (NAVSEA) and is available 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 shipbuilding for state and

Federal regulations. There are five types, twelve classes, and 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 structure, interior or exterior, for corrosion control. Except for trace levels, all types are free of lead, chromium, cadmium, and asbestos (see 3.2.3.1). All types have levels of hazardous air pollutants (HAP) that do not exceed applicable NESHAP levels (see 3.2.2.3). Dry type V, VI, VII, and VIII coating residues and debris are non-hazardous waste under U.S. Environmental Protection Agency (USEPA) regulations in effect on the date of this specification. Type VII coatings 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 of coating systems are as follows (see 6.2):

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 hazardous 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 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 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 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 qualification testing to this type have no solvent added to either the base resin component or the hardener component.

10 pounds) of powder.

1.2.2 Classes. 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 that may be used for fresh or potable water.

Class 6 - Class 6 coatings are no longer used.

Class 7 - A coating system for use in dedicated seawater ballast tanks. Class 7 coatings are not for use in tanks that may be used for freshwater, potable water, fuels, or other hydrocarbons.

Class 8 - Class 8 coatings are no longer used.

Class 9 - A coating system for use in dedicated potable or freshwater tanks. Class 9 coatings are not for use in tanks that may be used for seawater, fuels, or other hydrocarbons.

Class 10 - Class 10 coatings are no longer used.

Class 11 - A coating system for use in dedicated boiler feedwater (pure water) tanks. Class 11 coatings may not be used for seawater, potable water, freshwater, fuels, or other hydrocarbons.

Class 12 - Class 12 coatings are no longer used.

Class 13 - A coating system for use in dedicated collection, holding, and transfer (CHT) tanks. Class 13 coatings may not be used for seawater, potable water, freshwater, fuels, or other hydrocarbons.
