PERFORMANCE SPECIFICATION
COATING SYSTEMS FOR SHIP STRUCTURES
This 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 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, interior 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 residues and debris are
no
n-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 of 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
pigm
ents that are hazardous to workers or create hazardous waste is restricted to trace levels (see 3.2.3.1). May be
use
d 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
regu
lations.
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
un
der USEPA regulations. Coatings proposed for qualification 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 powder.
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.
