RULE §115.450Applicability and Definitions

    (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

      (iv) exposure to extreme environmental conditions, such as continuous outdoor exposure.

    (C) Heat-resistant coating--A coating that must withstand a temperature of at least 400 degrees Fahrenheit (204 degrees Celsius) during normal use.

    (D) Metallic coating--A coating that contains more than 0.042 pounds of metal particles per gallon of coating as applied. Metal particles are pieces of a pure elemental metal or a combination of elemental metals.

    (E) Pretreatment coating--A coating that contains no more than 12% solids by weight and at least 0.50% acid by weight; is used to provide surface etching; and is applied directly to metal surfaces to provide corrosion resistance, adhesion, and ease of stripping.

    (F) Solar-absorbent coating--A coating that has as its prime purpose the absorption of solar radiation.

  (4) Metal furniture coating--The coating of metal furniture including, but not limited to, tables, chairs, wastebaskets, beds, desks, lockers, benches, shelves, file cabinets, lamps, and other metal furniture products or the coating of any metal part that will be a part of a nonmetal furniture product.

    (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

      (iv) exposure to extreme environmental conditions, such as continuous outdoor exposure.

    (C) Heat-resistant coating--A coating that must withstand a temperature of at least 400 degrees Fahrenheit (204 degrees Celsius) during normal use.

    (D) Metallic coating--A coating containing more than 5.0 grams of metal particles per liter of coating as applied. Metal particles are pieces of a pure elemental metal or a combination of elemental metals.

    (E) Pretreatment coating--A coating that contains no more than 12% solids by weight and at least 0.50% acid by weight; is used to provide surface etching; and is applied directly to metal surfaces to provide corrosion resistance, adhesion, and ease of stripping.

    (F) Solar-absorbent coating--A coating that has as its primary purpose the absorption of solar radiation.

  (5) Miscellaneous metal and plastic parts--The following definitions apply to this surface coating category.

    (A) Camouflage coating--A coating used, principally by the military, to conceal equipment from detection.

    (B) Clear coat--A coating that lacks opacity or is transparent and may or may not have an undercoat that is used as a reflectant base or undertone color.

    (C) Drum (metal)--Any cylindrical metal shipping container with a capacity equal to or greater than 12 gallons but equal to or less than 110 gallons.

    (D) Electric-dissipating coating--A coating that rapidly dissipates a high-voltage electric charge.

    (E) Electric-insulting varnish--A non-convertible-type coating applied to electric motors, components of electric motors, or power transformers, to provide electrical, mechanical, and environmental protection or resistance.

    (F) EMI/RFI shielding--A coating used on electrical or electronic equipment to provide shielding against electromagnetic interference (EMI), radio frequency interference (RFI), or static discharge.

    (G) Etching filler--A coating that contains less than 23% solids by weight and at least 0.50% acid by weight and is used instead of applying a pretreatment coating followed by a primer.

    (H) Extreme high-gloss coating--A coating which, when tested by the American Society for Testing and Materials Test Method D523 adopted in 1980, shows a reflectance of 75% or more on a 60 degree meter.
