Vapor adsorber means a bed of activated carbon or other adsorbent into which Perc vapors are introduced and trapped for subsequent desorption.
Electrostatic spray means a method of applying a spray coating in which opposite electric charges are applied to the substrate and the coating. The coating is attracted to the substrate by the electrostatic potential between them.
Sorbent means a material that is used to soak up free liquids by either adsorption or absorption, or both. “Sorb” means to either adsorb or absorb, or both.
High global warming potential hydrofluorocarbons means any hydrofluorocarbons in a particular end use for which EPA’s Significant New Alternatives Policy (SNAP) program has identified other acceptable alternatives that have lower global warming potential. The SNAP list of alternatives is found at 40 CFR part 82, subpart G, with supplemental tables of alternatives available at (http://www.epa.gov/snap/ ).
Negative pressure respirator (tight fitting) means a respirator in which the air pressure inside the facepiece is negative during inhalation with respect to the ambient air pressure outside the respirator.
Reid vapor pressure means the vapor pressure of crude oil or other volatile petroleum products at 100 degrees Fahrenheit as determined by the latest edition of ASTM D6377 (RVPE): Standard Test Method for Determination of Vapor Pressure of Crude Oil.
Blend means seed consisting of more than one variety of a kind, each in excess of five percent by weight of the whole.
Pyrolysis means the thermal degradation of a substance in the absence of any oxidising agent, which does not form part of the substance itself, to produce char and gas and/or liquid; and
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.
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.
Cannabinoid edible means food or potable liquid into which a cannabinoid concentrate, cannabinoid extract or dried marijuana leaves or flowers have been incorporated.
Gasohol means a blended fuel composed of gasoline and fuel grade ethanol.
Color additive means a material that either:
Polymer means a substance consisting of molecules characterised by the sequence of one or more types of monomer units. Such molecules must be distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units. A polymer comprises the following:
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
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.
Solids means the nonvolatile portion of the coating that after drying makes up the dry film.
Blendstock means and includes any petroleum product component of motor fuel, such as naphtha, reformate, or toluene; or any oxygenate that can be blended for use in a motor fuel.
Flexible vinyl adhesive means an aerosol adhesive designed to bond flexible vinyl to substrates. Flexible vinyl means a nonrigid polyvinyl chloride plastic with at least five percent, by weight, of plasticizer content. A plasticizer is a material, such as a high boiling point organic solvent, that is incorporated into a vinyl to increase its flexibility, workability, or distensibility, and may be determined using ASTM Method E260-91 or from product formulation data.
Cyanoacrylate adhesive means any adhesive with a cyanoacrylate content of at least 95% by weight.
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
Feedstock Gas means natural gas used as a raw material for its chemical properties in creating an end product.
Dusting aid means a product designed or labeled to assist in removing dust and other soils from floors and other surfaces without leaving a wax or silicone based coating. “Dusting Aid” does not include “Pressurized Gas Duster.”
Polystyrene foam means blown polystyrene and expanded and
Pathogen means an organism that is capable of producing an infection or disease in a susceptible host.
Plasma arc incinerator means any enclosed device using a high intensity electrical discharge or arc as a source of heat followed by an afterburner using controlled flame combustion and which is not listed as an industrial furnace.
Radioactive marker means radioactive material placed subsurface or on a structure intended for subsurface use for the purpose of depth determination or direction orientation.
