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.
Analytical x-ray system means a group of components utilizing x-rays to determine the elemental composition or to examine the microstructure of materials.
Water supply system means a water distribution system, piping, connection fittings, valves and appurtenances within a building, structure, or premises. Water supply systems are also referred to commonly as premise plumbing systems.
Public water supply system means a system for the provision to the public of piped water for human consumption, if the system has at least fifteen service connections or regularly serves at least twenty-five individuals. The term includes any source of water and any collection, treatment, storage, and distribution facilities under control of the operator of the system and used primarily in connection with the system, and any collection or pretreatment storage facilities not under such control which are used primarily in connection with the system.
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.
Filter means material placed in the useful beam to preferentially absorb selected radiations.
Delivery System means the design and construction
HEPA filter means a high efficiency particulate absolute air filter capable of trapping and retaining 99.97 percent of fibers greater than 0.3 micrometers in mass median aerodynamic diameter equivalent.
X-ray system means an assemblage of components for the controlled production of x-rays. It includes minimally an x-ray high-voltage generator, an x-ray control, a tube housing assembly, a beam-limiting device, and the necessary supporting structures. Additional components which function with the system are considered integral parts of the system.
Diagnostic x-ray system means an x-ray system designed for irradiation of any part of the human or animal body for the purpose of diagnosis or visualization.
Fuel system means the components which store or transport fuel on board the vehicle and comprise the fuel tank system, all fuel and vapour lines, any non-tank mounted fuel pumps and the activated carbon canister.
Radiation therapy simulation system means a radiographic or fluoroscopic x-ray system intended for localizing the volume to be exposed during radiation therapy and confirming the position and size of the therapeutic irradiation field.
Registry System means the system operated by Registry Operator for Registered Names in the Registry TLD.
Irrigation System means such major, medium and minor irrigation system for harnessing water for irrigation and other allied uses from Government source and includes reservoirs, open head channels, diversion systems, lift irrigation schemes, anicuts, tanks, wells and the like.
Fluoroscopy means a technique for generating x-ray images and presenting them simultaneously and continuously as visible images. This term has the same meaning as the term "radioscopy" in the standards of the International Electrotechnical Commission.
E-Verify system means an Internet-based system operated by the United States Department of Homeland Security that allows participating employers to electronically verify the employment eligibility of newly hired employees; and
911 system means the set of network, database and customer premise equipment (CPE) components required to provide 911 service.
General purpose radiographic x-ray system means any radiographic x-ray system which, by design, is not limited to radiographic examination of specific anatomical regions.
COVID-19 symptoms means fever of 100.4 degrees Fahrenheit or higher, chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, or diarrhea, unless a licensed health care professional determines the person’s symptoms were caused by a known condition other than COVID-19.
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.
Single tomogram system means a CT x-ray system which obtains x-ray transmission data during a scan to produce a single tomogram.
Secondary Systems means control or power circuits that operate below 600 volts, AC or DC, including, but not limited to, any hardware, control or protective devices, cables, conductors, electric raceways, secondary equipment panels, transducers, batteries, chargers, and voltage and current transformers.
Disaster Recovery System means the system identified by the Supplier in the Supplier Solution which shall be used for the purpose of delivering the Disaster Recovery Services;
SDX System means the system used by NERC to exchange system data.
Tomographic plane means that geometric plane which is identified as corresponding to the output tomogram.
Conventional filtration treatment means a series of processes including coagulation, flocculation, sedimentation, and filtration resulting in substantial particulate removal.
