1.54" dated June 1973, available through the Government Printing Office
at (202) 512-2249 as document number A74062-00001.)
(T) Organic zinc specialty coating--Any coating derived
from zinc dust incorporated into an organic binder that contains more
than 960 grams of elemental zinc per liter (eight pounds per gallon)
of coating, as applied, and that is used for the expressed purpose
of corrosion protection.
(U) Pleasure craft--Any marine or fresh-water vessel
used by individuals for noncommercial, nonmilitary, and recreational
purposes that is less than 20 meters (65.6 feet) in length. A vessel
rented exclusively to, or chartered for, individuals for such purposes
shall be considered a pleasure craft.
(V) Pretreatment wash primer specialty coating--Any
coating that contains a minimum of 0.5% acid by weight that is applied
only to bare metal surfaces to etch the metal surface for corrosion
resistance and adhesion of subsequent coatings.
(W) Repair and maintenance of thermoplastic coating
of commercial vessels (specialty coating)--Any vinyl, chlorinated
rubber, or bituminous resin coating that is applied over the same
type of existing coating to perform the partial recoating of any in-use
commercial vessel. (This definition does not include coal tar epoxy
coatings, which are considered "general use" coatings.)
(X) Rubber camouflage specialty coating--Any specially
formulated epoxy coating used as a camouflage topcoat for exterior
submarine hulls and sonar domes.
(Y) Sealant for thermal spray aluminum--Any epoxy coating
applied to thermal spray aluminum surfaces at a maximum thickness
of one dry mil.
(Z) Ship--Any marine or fresh-water vessel, including
self-propelled vessels, those propelled by other craft (barges), and
navigational aids (buoys). This definition includes, but is not limited
to, all military and Coast Guard vessels, commercial cargo and passenger
(cruise) ships, ferries, barges, tankers, container ships, patrol
and pilot boats, and dredges. Pleasure craft and offshore oil or gas
drilling platforms are not considered ships.
(AA) Shipbuilding and ship repair operations--Any building,
repair, repainting, converting, or alteration of ships or offshore
oil or gas drilling platforms.
(BB) Special marking specialty coating--Any coating
that is used for safety or identification applications, such as ship
numbers and markings on flight decks.
(CC) Specialty interior coating--Any coating used on
interior surfaces aboard United States military vessels pursuant to
a coating specification that requires the coating to meet specified
fire retardant and low toxicity requirements, in addition to the other
applicable military physical and performance requirements.
(DD) Tack coat specialty coating--Any thin film epoxy
coating applied at a maximum thickness of two dry mils to prepare
an epoxy coating that has dried beyond the time limit specified by
the manufacturer for the application of the next coat.
(EE) Undersea weapons systems specialty coating--Any
coating applied to any component of a weapons system intended to be
launched or fired from under the sea.
(FF) Weld-through preconstruction primer (specialty
coating)--A coating that provides corrosion protection for steel during
inventory, is typically applied at less than one mil dry film thickness,
does not require removal prior to welding, is temperature resistant
(burn back from a weld is less than 1.25 centimeters (0.5 inches)),
and does not normally require removal before applying film-building
coatings, including inorganic zinc high-build coatings. When constructing
new vessels, there may be a need to remove areas of weld-through preconstruction
primer due to surface damage or contamination prior to application
of film-building coatings.
(12) Automobile and light-duty truck manufacturing.
(A) Automobile coating--The assembly-line coating of
passenger cars, or passenger car derivatives, capable of seating 12
or fewer passengers.
(B) Light-duty truck coating--The assembly-line coating

weight or less and designed primarily for the transportation of property,
or derivatives such as pickups, vans, and window vans.

of a pigmented basecoat portion and a transparent clearcoat portion.
The VOC content of a basecoat (BCCA-AG)/clearcoat (cc) system shall
be calculated according to the following formula.

(B) Precoat--Any coating that is applied to bare metal
to deactivate the metal surface for corrosion resistance to a subsequent
water-based primer. This coating is applied to bare metal solely for
the prevention of flash rusting.
(C) Pretreatment--Any coating which contains a minimum
of 0.5% acid by weight that is applied directly to bare metal surfaces
to etch the metal surface for corrosion resistance and adhesion of

(D) Primer or primer surfacers--Any base coat, sealer,
or intermediate coat which is applied prior to colorant or aesthetic
coats.
(E) Sealers--Coatings that are formulated with resins
which, when dried, are not readily soluble in typical solvents. These
coatings act as a shield for surfaces over which they are sprayed
by resisting the penetration of solvents which are in the final topcoat.
(F) Specialty coatings--Coatings or additives which
are necessary due to unusual job performance requirements. These coatings
or additives prevent the occurrence of surface defects and impart
or improve desirable coating properties. These products include, but
are not limited to, uniform finish blenders, elastomeric materials
for coating of flexible plastic parts, coatings for non-metallic parts,
jambing clear coatings, gloss flatteners, and anti-glare/safety coatings.
