Section R307-343-3 - Definitions
The following additional definitions apply to R307-343:
"As applied" means the volatile organic compound and solids content of the finishing material that is actually used for coating the substrate. It includes the contribution of materials used for in-house dilution of the finishing material.
"Control system" means the combination of capture and control devices used to reduce emissions to the atmosphere.
"Conventional Air Spray" means a spray coating method in which the coating is atomized by mixing it with compressed air at an air pressure greater than ten pounds per square inch (gauge) at the point of atomization. Airless, air assisted airless spray technologies, and electrostatic spray technology are not considered conventional air spray.
"Finishing material" means a coating used in the wood furniture industry, including basecoats, stains, washcoats, sealers, and topcoats.
"Finishing Operation" means those activities in which a finishing material is applied to a substrate and is subsequently air-dried, cured in an oven, or cured by radiation.
"Sealer" means a finishing material used to seal the pores of a wood substrate before additional coats of finishing material are applied. A washcoat used to optimize aesthetics is not a sealer.
"Solids" means the part of the coating that remains after the coating is dried or cured; solids content is determined using data from EPA Method 24.
"Stain" means any color coat having a solids content by weight of no more than 8.0% that is applied in single or multiple coats directly to the substrate, including nongrain raising stains, equalizer stains, sap stains, body stains, no-wipe stains, penetrating stains, and toners.
"Topcoat" means the last film-building finishing material applied in a finishing system. Non-permanent final finishes are not topcoats.
"Touch-up and Repair" means the application of finishing materials to cover minor finishing imperfections.
"Washcoat" means a transparent special purpose coating having a solids content by weight of 12.0% or less that is applied over initial stains to protect and control color and to stiffen the wood fibers in order to aid sanding.
"Washoff operations" means those operations in which organic solvent is used to remove coating from a substrate.
"Wood furniture" means any product made of wood that is manufactured under any of the following standard industrial classification codes: 2434, 2511, 2512, 2517, 2519, 2521, 2531, 2541, 2599, or 5712. This includes wood products such as rattan or wicker and engineered wood products such as particleboard.
"Wood furniture manufacturing operations" means the finishing, cleaning, and washoff operations associated with the production of wood furniture or wood furniture components.
