Coating means a material applied onto or impregnated into a substrate for protective, decorative, or functional purposes. Such materials include, but are not limited to, paints, varnishes, sealers, and stains.
Roll coating means the application of a coating material to a substrate by means of hard rubber or steel rolls.
Flat coating means a coating that is not defined under any other definition in this section and that registers gloss less than 15 on an 85-degree meter or less than 5 on a 60-degree meter.
Metallic coating means a coating which contains more than five 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.
Flow coating means a coating labeled and formulated exclusively for use by electric power companies or their subcontractors to maintain the protective coating systems present on utility transformer units.
Floor coating means an opaque coating that is labeled and designed for application to flooring, including but not limited to, decks, porches, steps, and other horizontal surfaces which may be subject to foot traffic.
Antenna coating means a coating labeled and formulated exclusively for application to equipment and associated structural appurtenances that are used to receive or transmit electromagnetic signals.
Total tetrahydrocannabinol means the sum of the percentage by weight of tetrahydrocannabinolic acid multiplied by eight hundred seventy-seven thousandths plus the percentage of weight of tetrahydrocannabinol.
Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);
Nuclear coating means any protective coating used to seal porous surfaces, such as steel or concrete, that otherwise would be subject to intrusion by radioactive materials. These coatings must be resistant to long term (service life) cumulative radiation exposure (ASTM D4082-83**), relatively easy to decontaminate (ASTM D4256-83**), and resistant to various chemicals to which the coatings are likely to be exposed (ASTM 3912-80**). General protective requirements are outlined by the Department of Energy (formerly United States Atomic Energy Commission Regulatory Guide 1.54**).
Defoliant means any substance or mixture of substances intended for causing the leaves or foliage to drop from a plant, with or without causing abscission.
Geothermal fluid means water in any form at temperatures greater than 120
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Air dried coating means a coating that is dried by the use of air or forced warm air at temperatures up to 1940F (900C).
Low-solids coating means a coating containing 0.12 kilogram or less of solids per liter (one pound or less of solids per gallon) of coating material.
Touch-up coating means a coating used to cover minor coating imperfections appearing after the main coating operation.
Undercoating means any aerosol product designed to impart a protective, non-paint layer to the undercarriage, trunk interior, and/or firewall of motor vehicles to prevent the formation of rust or to deaden sound. “Undercoating” includes, but is not limited to, rubberized, mastic, or asphaltic products.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
Asphalt means a dark brown to black cement-like material (solid, semisolid, or liquid in consistency) in which the predominating constituents are bitumens which occur in nature as such or which are obtained as residue in refining petroleum.
Automotive windshield washer fluid means any liquid designed for use in a motor vehicle windshield washer system either as an antifreeze or for the purpose of cleaning, washing, or wetting the windshield. Automotive windshield washer fluid does not include fluids placed by the manufacturer in a new vehicle.
Tube means an x-ray tube, unless otherwise specified.
Fertilizer means any substance or mixture of substances that contains one or more recognized plant nutrients and promotes plant growth, or controls soil acidity or alkalinity, or provides other soil enrichment, or provides other corrective measures to the soil.
Gasification means the substoichiometric oxidation or steam reformation of a substance to produce a gaseous mixture containing two or more of the following: (i) oxides of carbon; (ii) methane; and (iii) hydrogen;
Tetrahydrocannabinol means the natural or synthetic equivalents of the substances contained in the plant, or in the resinous extractives of, Cannabis sativa, or any synthetic substances, compounds, salts, or derivatives of the plant or chemicals and their isomers with similar chemical structure and pharmacological activity.
Pretreatment coating means a coating which contains no more than 12% solids by weight, and at least 0.5% 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.
Fossil fuel-fired means, with regard to a unit:
