Sensor means any measurement device that is not part of the vehicle itself but installed to determine parameters other than the concentration of gaseous and particle pollutants and the exhaust mass flow.
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.
HEPA filter means high-efficiency particulate air filters that are rated to achieve a minimum initial particle-removal efficiency of 99.97 per cent using ASTM F 1471– 93 or equivalent standard;
Membrane filtration means a pressure or vacuum driven separation process in which particulate matter larger than one micrometer is rejected by an engineered barrier, primarily through a size exclusion mechanism, and which has a measurable removal efficiency of a target organism that can be verified through the application of a direct integrity test. This definition includes the common membrane technologies of microfiltration, ultrafiltration, nanofiltration, and reverse osmosis.
Duct is a single enclosed path to house facilities to provide Telecommunications Services.
Filter means material placed in the useful beam to preferentially absorb selected radiations.
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.
Cyanoacrylate adhesive means any adhesive with a cyanoacrylate content of at least 95% by weight.
Engine degreaser means a cleaning product designed to remove grease, grime, oil and other contaminants from the external surfaces of engines and other mechanical parts.
medium voltage means the set of nominal voltage levels that lie above low voltage and below high voltage in the range of 1 kV < Un 44 kV. [SANS 1019]
Leak-detection system means a system capable of detecting the failure of either the primary or secondary containment structure or the presence of a release of hazardous waste or accumulated liquid in the secondary containment structure. Such a system must employ operational controls (e.g., daily visual inspections for releases into the secondary containment system of aboveground tanks) or consist of an interstitial monitoring device designed to detect continuously and automatically the failure of the primary or secondary containment structure or the presence of a release of hazardous waste into the secondary containment structure.
Thermostat means a temperature control device that contains metallic mercury in an ampule attached to a bimetal sensing element, and mercury-containing ampules that have been removed from these temperature control devices in compliance with the requirements of § 273.13(c)(2) or 273.33(c)(2).
Slug loading means any pollutant, including oxygen demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration as to cause interference in the POTW.
Overflow means the intentional or unintentional diversion of flow from the collection and transport systems, including pumping facilities.
water meter means any apparatus for measuring or showing the volume of water supplied to, or of effluent discharged from any premises;
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
Valve means a device used to control the flow of water in the irrigation system.
Smoke means the gases, particles, or vapors released into the air as a result of combustion, electrical ignition or vaporization, when the apparent or usual purpose of the combustion, electrical ignition or vaporization is human inhalation of the byproducts, except when the combusting or vaporizing of materials contains no tobacco or nicotine and the purpose of the inhalation is solely olfactory, such as, for example, smoke from incense. The term "smoke" includes, but is not limited to, tobacco smoke, electronic cigarette vapors, and cannabis smoke.
Floodproofing means any combination of structural and nonstructural additions, changes, or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitation facilities, structures, and their contents.
Mist spray adhesive means any aerosol which is not a special purpose spray adhesive and which delivers a particle or mist spray, resulting in the formation of fine, discrete particles that yield a generally uniform and smooth application of adhesive to the substrate.
Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
fire hydrant means a fire plug or fixed pillar fire hydrant;
Cabinet x-ray system means an x-ray system with the x-ray tube installed in an enclosure independent of existing architectural structures except the floor on which it may be placed. The cabinet x-ray system is intended to contain at least that portion of a material being irradiated, provide radiation attenuation, and exclude personnel from its interior during generation of radiation. Included are all x-ray systems designed primarily for the inspection of carry-on baggage at airline, railroad, and bus terminals, and in similar facilities. An x-ray tube used within a shielded part of a building, or x-ray equipment that may temporarily or occasionally incorporate portable shielding, is not considered a cabinet x-ray system.
Grease interceptor means a watertight device designed to intercept and retain or remove grease and fatty substances. The device may be located inside (grease separator) or outside (grease tank or grease trap) a facility.
Irrigation means application of water to land areas to supply the water needs of
Aerosol adhesive means any adhesive packaged as an aerosol product in which the spray mechanism is permanently housed in a nonrefillable can designed for hand-held application without the need for ancillary hoses or spray equipment. Aerosol adhesives include special purpose spray adhesives, mist spray adhesives, and web spray adhesives.
