MIL-PRF-23236 Coating Systems For Ship StructuresThis 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 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.

4. VERIFICATION

4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:

Qualification inspection (see 4.2).

Conformance inspection (see 4.3).

4.2 Qualification inspection. Qualification inspection shall be as follows:

a. Qualification approval for Types VI and VII shall also constitute approval for Type V coating systems of

the same class and grade.

b. Qualification approval for Type VII shall also constitute approval for Types V and VI coatings of the same

class and grade.

Qualification approval for Types VIII and VIIIa is unique and not extended to other types.

4.3 Conformance inspection. Conformance inspection shall consist of the conformance tests specified in

table V.

4.4 Panel preparation. Test plates of the nature and size specified in the applicable test method shall be coated

in accordance with the manufacturer's application instructions. Each individual coating of the coating system shall

be mixed in accordance with the manufacturer's mixing instructions.

4.5 Test procedures. Tests shall be conducted as specified in table V. The temperature at which tests are

conducted shall be in accordance with the applicable FED-STD-141 and ASTM test methods identified in table V.

For reduced temperature materials (Grades A and B), tests shall be conducted at the low end of the temperature

range. Unless otherwise specified herein, test panel dimensions and test conditions, such as temperature, are

nominal.
