RULE §115.450Applicability and Definitions

    (I) Extreme performance coating--A coating used on a metal or plastic surface where the coated surface is, in its intended use, subject to one of the following conditions. Extreme performance coatings include, but are not limited to, coatings applied to locomotives, railroad cars, farm machinery, marine shipping containers, downhole drilling equipment, and heavy-duty trucks:

      (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.

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

    (K) High performance architectural coating--A coating used to protect architectural subsections and meets the requirements of the American Architectural Manufacturers Association's publication number AAMA 2604-05 (Voluntary Specification, Performance Requirements and Test Procedures for High Performance Organic Coatings on Aluminum Extrusions and Panels) or 2605-05 (Voluntary Specification, Performance Requirements and Test Procedures for Superior Performing Organic Coatings on Aluminum Extrusions and Panels).

    (L) High temperature coating--A coating that is certified to withstand a temperature of 1000 degrees Fahrenheit (538 degrees Celsius) for 24 hours.

    (M) Mask coating--A thin film coating applied through a template to coat a small portion of a substrate.

    (N) 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.

    (O) Military specification coating--A coating that has a formulation approved by a United States Military Agency for use on military equipment.

    (P) Mold-seal coating--The initial coating applied to a new mold or a repaired mold to provide a smooth surface that when coated with a mold release coating, prevents products from sticking to the mold.

    (Q) Miscellaneous metal parts and products--Parts and products considered miscellaneous metal parts and products include:

      (i) large farm machinery (harvesting, fertilizing, and planting machines, tractors, combines, etc.);

      (ii) small farm machinery (lawn and garden tractors, lawn mowers, rototillers, etc.);

      (iii) small appliances (fans, mixers, blenders, crock pots, dehumidifiers, vacuum cleaners, etc.);

      (iv) commercial machinery (computers and auxiliary equipment, typewriters, calculators, vending machines, etc.);

      (v) industrial machinery (pumps, compressors, conveyor components, fans, blowers, transformers, etc.);

      (vi) fabricated metal products (metal-covered doors, frames, etc.); and

      (vii) any other category of coated metal products, including, but not limited to, those that are included in the Standard Industrial Classification Code major group 33 (primary metal industries), major group 34 (fabricated metal products), major group 35 (nonelectrical machinery), major group 36 (electrical machinery), major group 37 (transportation equipment), major group 38 (miscellaneous instruments), and major group 39 (miscellaneous manufacturing industries). Excluded are those surface coating processes specified in §115.420(c)(1) - (8) and (10) - (16) of this title (relating to Surface Coating Definitions) and paragraphs (1) - (4) and (6) - (8) of this subsection.

    (R) Miscellaneous plastic parts and products--Parts and products considered miscellaneous plastic parts and products include, but are not limited to:

      (i) molded plastic parts;

      (ii) small and large farm machinery;

      (iii) commercial and industrial machinery and equipment;

      (iv) interior or exterior automotive parts;

      (v) construction equipment;

      (vi) motor vehicle accessories;

      (vii) bicycles and sporting goods;

      (viii) toys;

      (ix) recreational vehicles;

      (x) lawn and garden equipment;

      (xi) laboratory and medical equipment;

      (xii) electronic equipment; and

      (xiii) other industrial and household products. Excluded are those surface coating processes specified in §115.420(c)(1) - (16) of this title and paragraphs (1) - (4) and (6) - (8) of this subsection.

    (S) Multi-colored coating--A coating that exhibits more than one color when applied, is packaged in a single container, and applied in a single coat.

    (T) Off-site job shop--A non-manufacturer of metal or plastic parts and products that applies coatings to such products at a site under contract with one or more parties that operate under separate ownership and control.

    (U) Optical coating--A coating applied to an optical lens.

    (V) Pail (metal)--Any cylindrical metal shipping container with a capacity equal to or greater than 1 gallon but less than 12 gallons and constructed of 29 gauge or heavier material.

    (W) Pan-backing coating--A coating applied to the surface of pots, pans, or other cooking implements that are exposed directly to a flame or other heating elements.

    (X) Prefabricated architectural component coating--A coating applied to metal parts and products that are to be used as an architectural structure.

    (Y) 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.

    (Z) Repair coating--A coating used to re-coat portions of a previously coated product that has sustained mechanical damage to the coating following normal surface coating processes.

    (AA) Safety-indicating coating--A coating that changes physical characteristics, such as color, to indicate unsafe conditions.

    (BB) Shock-free coating--A coating applied to electrical components to protect the user from electric shock. The coating has characteristics of being low-capacitance and high-resistance and having resistance to breaking down under high voltage.

    (CC) Silicone-release coating--A coating that contains silicone resin and is intended to prevent food from sticking to metal surfaces such as baking pans.

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

    (EE) Stencil coating--A pigmented coating or ink that is rolled or brushed onto a template or stamp in order to add identifying letters, symbols, or numbers.

    (FF) Touch-up coating--A coating used to cover minor coating imperfections appearing after the main surface coating process.

    (GG) Translucent coating--A coating that contains binders and pigment and formulated to form a colored, but not opaque, film.

    (HH) Vacuum-metalizing coating--The undercoat applied to the substrate on which the metal is deposited or the overcoat applied directly to the metal film. Vacuum metalizing or physical vapor deposition is the process whereby metal is vaporized and deposited on a substrate in a vacuum chamber.

  (6) Motor vehicle materials--The following definitions apply to this surface coating category.

    (A) Motor vehicle bedliner--A multi-component coating used in a process that is not an automobile or light-duty truck manufacturing coating process and is applied to a cargo bed after the application of topcoat to provide additional durability and chip resistance.

    (B) Motor vehicle cavity wax--A coating used in a process that is not an automobile or light-duty truck manufacturing coating process and is applied into the cavities of the vehicle primarily for the purpose of enhancing corrosion protection.

    (C) Motor vehicle deadener--A coating used in a process that is not an automobile or light-duty truck manufacturing coating process and is applied to selected vehicle surfaces primarily for the purpose of reducing the sound of road noise in the passenger compartment.
