| (L) Automobile and light-duty truck weather strip adhesive--An
adhesive used in an automobile or light-duty truck assembly surface
coating process and applied to weather-stripping materials for the
purpose of bonding the weather-stripping material to the surface of
the vehicle.
(M) Automobile assembly surface coating process--The
assembly-line coating of new passenger cars, or passenger car derivatives,
capable of seating 12 or fewer passengers.
(N) Electrodeposition primer--A process of applying
a protective, corrosion-resistant waterborne primer on exterior and
interior surfaces that provides thorough coverage of recessed areas.
Electrodeposition primer is a dip-coating method that uses an electrical
field to apply or deposit the conductive coating onto the part; the
object being painted acts as an electrode that is oppositely charged
from the particles of paint in the dip tank. Electrodeposition primer
is also referred to as E-Coat, Uni-Prime, and ELPO Primer.
(O) Final repair--The operation(s) performed and coating(s)
applied to completely assembled motor vehicles or to parts that are
not yet on a completely assembled vehicle to correct damage or imperfections
in the coating. The curing of the coatings applied in these operations
is accomplished at a lower temperature than that used for curing primer-surfacer
and topcoat. This lower temperature cure avoids the need to send parts
that are not yet on a completely assembled vehicle through the same
type of curing process used for primer-surfacer and topcoat and is
necessary to protect heat-sensitive components on completely assembled
vehicles.
(P) In-line repair--The operation(s) performed and
coating(s) applied to correct damage or imperfections in the topcoat
on parts that are not yet on a completely assembled vehicle. The curing
of the coatings applied in these operations is accomplished at essentially
the same temperature as that used for curing the previously applied
topcoat. In-line repair is also referred to as high-bake repair or
high-bake reprocess. In-line repair is considered part of the topcoat
operation.
(Q) Light-duty truck assembly surface coating process--The
assembly-line coating of new motor vehicles rated at 8,500 pounds
gross vehicle weight or less and designed primarily for the transportation
of property, or derivatives such as pickups, vans, and window vans.
(R) Primer-surfacer--An intermediate protective coating
applied over the electrodeposition primer and under the topcoat. Primer-surfacer
provides adhesion, protection, and appearance properties to the total
finish. Primer-surfacer is also referred to as guide coat or surfacer.
Primer-surfacer operations may include other coatings (e.g., anti-chip,
lower-body anti-chip, chip-resistant edge primer, spot primer, blackout,
deadener, interior color, basecoat replacement coating, etc.) that
are applied in the same spray booth(s).
(S) Topcoat--The final coating system applied to provide
the final color or a protective finish. The topcoat may be a monocoat
color or basecoat/clearcoat system. In-line repair and two-tone are
part of topcoat. Topcoat operations may include other coatings (e.g.,
blackout, interior color, etc.) that are applied in the same spray
booth(s).
(T) Solids turnover ratio (RT')--The ratio of total
volume of coating solids that is added to the electrodeposition primer
system (EDP) in a calendar month divided by the total volume design
capacity of the EDP system.
(2) Automotive/transportation and business machine
plastic parts--The following definitions apply to this surface coating
category.
(A) Adhesion prime--A coating that is applied to a
polyolefin part to promote the adhesion of a subsequent coating. An
adhesion prime is clearly identified as an adhesion prime or adhesion
promoter on its accompanying material safety data sheet.
(B) Automotive/transportation plastic parts--Interior
and exterior plastic components of automobiles, trucks, tractors,
lawnmowers, and other mobile equipment.
(C) Black coating--A coating that has a maximum lightness
of 23 units and a saturation less than 2.8, where saturation equals
the square root of A2 + B2. These criteria are based on Cielab color
space, 0/45 geometry. For spherical geometry, specular included, maximum
lightness is 33 units.
(D) Business machine--A device that uses electronic
or mechanical methods to process information, perform calculations,
print or copy information, or convert sound into electrical impulses
for transmission. This definition includes devices listed in Standard
Industrial Classification codes 3572, 3573, 3574, 3579, and 3661 and
photocopy machines, a subcategory of Standard Industrial Classification
code 3861.
(E) Clear coating--A coating that lacks color and opacity
or is transparent and that uses the undercoat as a reflectant base
or undertone color.
(F) Coating of plastic parts of automobiles and trucks--The
coating of any plastic part that is or will be assembled with other
parts to form an automobile or truck.
(G) Coating of business machine plastic parts--The
coating of any plastic part that is or will be assembled with other
parts to form a business machine.
(H) Electrostatic prep coat--A coating that is applied
to a plastic part solely to provide conductivity for the subsequent
application of a prime, a topcoat, or other coating through the use
of electrostatic application methods. An electrostatic prep coat is
clearly identified as an electrostatic prep coat on its accompanying
material safety data sheet.
(I) Flexible coating--A coating that is required to
comply with engineering specifications for impact resistance, mandrel
bend, or elongation as defined by the original equipment manufacturer.
(J) Fog coat--A coating that is applied to a plastic
part for the purpose of color matching without masking a molded-in
texture. A fog coat may not be applied at a thickness of more than
0.5 mil of coating solids.
(K) Gloss reducer--A coating that is applied to a plastic
part solely to reduce the shine of the part. A gloss reducer may not
be applied at a thickness of more than 0.5 mil of coating solids.
(L) Red coating--A coating that meets all of the following
criteria:
(i) yellow limit: the hue of hostaperm scarlet;
(ii) blue limit: the hue of monastral red-violet;
(iii) lightness limit for metallics: 35% aluminum flake;
(iv) lightness limit for solids: 50% titanium dioxide
white;
(v) solid reds: hue angle of -11 to 38 degrees and
maximum lightness of 23 to 45 units; and
(vi) metallic reds: hue angle of -16 to 35 degrees
and maximum lightness of 28 to 45 units. These criteria are based
on Cielab color space, 0/45 geometry. For spherical geometry, specular
included, the upper limit is 49 units. The maximum lightness varies
as the hue moves from violet to orange. This is a natural consequence
of the strength of the colorants, and real colors show this effect.
(M) Resist coat--A coating that is applied to a plastic
part before metallic plating to prevent deposits of metal on portions
of the plastic part.
(N) Stencil coat--A coating that is applied over a
stencil to a plastic part at a thickness of 1.0 mil or less of coating
solids. Stencil coats are most frequently letters, numbers, or decorative
designs.
(O) Texture coat--A coating that is applied to a plastic
part which, in its finished form, consists of discrete raised spots
of the coating.
(P) Vacuum-metalizing coatings--Topcoats and basecoats
that are used in the vacuum-metalizing process.
(3) Large appliance coating--The coating of doors,
cases, lids, panels, and interior support parts of residential and
commercial washers, dryers, ranges, refrigerators, freezers, water
heaters, dishwashers, trash compactors, air conditioners, and other
large appliances.
(A) Extreme high-gloss coating--A coating which, when
tested by the American Society for Testing Material Test Method D523
adopted in 1980, shows a reflectance of 75% or more on a 60 degree
meter.
(B) Extreme performance coating--A coating used on
a metal surface where the coated surface is, in its intended use,
subject to:
(i) chronic exposure to corrosive, caustic or acidic
agents, chemicals, chemical fumes, chemical mixtures, or solutions;
(ii) repeated exposure to temperatures in excess of
250 degrees Fahrenheit (121 degrees Celsius);
(iii) repeated heavy abrasion, including mechanical
wear and repeated scrubbing with industrial grade solvents, cleansers,
or scouring agents; or
