R307-353-4. Definitions  


Latest version.
  •   The following additional definitions apply to R307-353:

      "Air dried coating" means coatings that are dried by the use of air or a forced warm air at temperatures up to 194 degrees Fahrenheit.

      "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.

      "Baked coating" means coatings that are cured at a temperature at or above 194 degrees Fahrenheit.

      "Electric-insulating and thermal-conducting" means a coating that displays an electrical insulation of at least 1000 volts DC per mil on a flat test plate and an average thermal conductivity of at least 0.27 BTU per hour-foot-degree-Fahrenheit.

      "Magnetic data storage disk coating" means a coating used on a metal disk which stores data magnetically.

      "Medical device" means an instrument, apparatus, implement, machine, contrivance, implant, in vitro reagent or other similar article including any component or accessory, that is intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or is intended to affect the structure or any function of the body. For the purpose of this rule, a medical device shall also include associated manufacturing or assembly apparatus.

      "Metallic coating" means a coating which contains more than 5 grams of metal particles per liter of coating as applied.

      "Military specification coating" means a coating which has a formulation approved by a United States military agency for use on military equipment.

      "Mirror backing" means the coating applied over the silvered surface of a mirror.

      "Mold-seal coating" means the initial coating applied to a new mold or a repaired mold to provide a smooth surface which, when coated with a mold release coating, prevents products from sticking to the mold.

      "Multi-colored coating" means a coating which exhibits more than one color when applied, and which is packaged in a single container and applied in a single coat.

      "Multi-component coating" means a coating requiring the addition of a separate reactive resin, commonly known as a catalyst, before application to form an acceptable dry film.

      "One-component coating" means a coating that is ready for application as it comes out of its container to from an acceptable dry film. A thinner necessary to reduce the viscosity is not considered a component.

      "Optical coating" means a coating applied to an optical lens.

      "Plastic" means a substrate containing one or more resigns that may be solid, porous, flexible, or rigid, and includes fiber reinforced plastic composites.

      "Primer" means a coating applied to a surface to provide a firm bond between the substrate and subsequent coats.

      "Repair coating" means a coating used to recoat portions of a part or product which has sustained mechanical damage to the coating.

      "Roller Coated" means a type of coating application equipment that utilizes a series of mechanical rollers to form a thin coating film on the surface of a roller, which is then applied to a substrate by moving the substrate underneath the roller.

      "Safety-indicating coating" means a coating which changes physical characteristics, such as color, to indicate unsafe condition.

      "Stencil coating" means an ink or a coating which is rolled or brushed onto a template or stamp in order to add identifying letters or numbers to metal parts and products.

      "Textured finish" means a rough surface produced by spraying and splattering large drops of coating onto a previously applied coating. The coatings used to form the appearance of the textured finish are referred to as textured coatings.

      "Touch-up coating" means a coating used to cover minor coating imperfections appearing after the main coating operation.

      "Topcoat" means the last film-building finishing material applied in a finishing system. Non-permanent final finishes are not topcoats.
