It does not include combustible liquids or flammable liquids carried in a tank for use only by machinery and boats carried aboard the processing vessel, or for use only by vessels that are directly supporting the processing vessel's primary operations.

*Certificate of compliance* means the document issued and displayed in accordance with § 105.10.

*Combustible liquid* means any liquid having a flashpoint above 80 °F (as determined from an open cup tester, as used for testing of burning oils). A *Grade D* combustible liquid is one having a flashpoint above 80 °F and below 150 °F. A *Grade E* combustible liquid is one having a flashpoint of 150 °F or above.

*Commercial fish processing vessel* means a self-propelled manned vessel that commercially prepares fish or fish products other than by gutting, decapitating, gilling, skinning, shucking, icing, freezing, or brine chilling.

*Dispensing* means the unloading of any quantity of flammable or combustible liquids in bulk.

*Examination* means a careful and critical assessment of the vessel and its appurtenances carried out by an authorized examiner or an organization designated by the Commandant, U.S. Coast Guard. This includes, where necessary, a visual assessment of the vessel's hull, structures, electrical systems, and machinery, supplemented by other means such as measurement and/or nondestructive testing.

*Flammable liquid* means any liquid that gives off flammable vapors (as determined by flashpoint from an open cup tester, as used for testing of burning oils) at or below 80 °F. Flammable liquids are referred to by grades as follows:

1/2 pounds, as measured in accordance with ASTM D 323.

(3) *Grade C.* Any flammable liquid having a Reid vapor pressure of 8
1/2 pounds or less and a flashpoint of 80 °F or below, as measured in accordance with ASTM D 323.

*Fuel tank* means a tank other than a dispensing tank used to transport flammable or combustible liquid for the purpose of supplying fuel for propulsion of the vessel to which it is attached.

*Limited quantities* means not more than 20 percent of a vessel's deadweight tonnage as applied to bulk liquid cargoes or carried in permanent or temporary tanks.
