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.
Loop Concentrator/Multiplexer or "LCM" is the Network Element that does one or more of the following: aggregates lower bit rate or bandwidth signals to higher bit rate or bandwidth signals (multiplexing); disaggregates higher bit rate or bandwidth signals to lower bit rate or bandwidth signals (demultiplexing); aggregates a specified number of signals or channels to fewer channels (concentrating); performs signal conversion, including encoding of signals (e.g., analog to digital and digital to analog signal conversion); or in some instances performs electrical to optical (E/O) conversion. LCM includes DLC, and D4 channel banks and may be located in Remote Terminals or Central Offices.
Stack means any point in a source designed to emit solids, liquids, or gases into the air, including a pipe or duct but not including flares.
low voltage means the set of nominal voltage levels that are used for the distribution of electricity and whose upper limit is generally accepted to be an a.c. voltage of 1000V ( or a d.c. voltage of 1500 V). [SANS 1019]
Check Meter means the Buyer revenue-quality meter section or meter(s), which Buyer may require at its discretion, as set forth in Section 3.08(b) and will include those devices normally supplied by Buyer or Seller under the applicable utility Electric Service Requirements.
Synchronous means existing or occurring at the same time.
DNS test Means one non-‐recursive DNS query sent to a particular “IP address” (via UDP or TCP). If DNSSEC is offered in the queried DNS zone, for a query to be considered answered, the signatures must be positively verified against a corresponding DS record published in the parent zone or, if the parent is not signed, against a statically configured Trust Anchor. The answer to the query must contain the corresponding information from the Registry System, otherwise the query will be considered unanswered. A query with a “DNS resolution RTT” 5 times higher than the corresponding SLR, will be considered unanswered. The possible results to a DNS test are: a number in milliseconds corresponding to the “DNS resolution RTT” or, undefined/unanswered.
Cathode ray tube or “CRT” means a vacuum tube, composed primarily of glass, which is the visual or video display component of an electronic device. A “used, intact CRT” means a CRT whose vacuum has not been released. A “used, broken CRT” means glass removed from its housing or casing whose vacuum has been released.
PNode has the meaning set forth in the CAISO Tariff.
Motorized wheelchair means any self-propelled vehicle designed for, and used by, a handicapped person and that is incapable of a speed in excess of eight miles per hour.
Ethernet means a family of computer networking technologies for LANs.
Rack means a mechanism for delivering motor vehicle fuel or diesel from a refinery or terminal into a truck, trailer, railroad car, or other means of non-bulk transfer.
Skateboard means a board with small wheels that is usually ridden by a person. For purposes of these rules, a nonmotorized scooter (a board with a handle) is considered a skateboard.
Diameter means the diameter of the stem of a tree measured outside the bark at a specified point of measurement.
Backflow means the backflow of water or other liquids, mixtures, or substances into the distribution pipes of a potable water system from any source other than the intended source of the potable water supply.
Hydraulic lift tank means a tank holding hydraulic fluid for a closed-loop mechanical system that uses compressed air or hydraulic fluid to operate lifts, elevators, and other similar devices.
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.
X-ray tube means any electron tube which is designed to be used primarily for the production of X-rays.
Cold Weather Alert means the notice that PJM provides to PJM Members, Transmission Owners, resource owners and operators, customers, and regulators to prepare personnel and facilities for expected extreme cold weather conditions.
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.
Automotive windshield washer fluid means any liquid designed for use in a motor vehicle windshield washer system either as an antifreeze or for the purpose of cleaning, washing, or wetting the windshield. Automotive windshield washer fluid does not include fluids placed by the manufacturer in a new vehicle.
Electric bicycle means a “class 1 electric bicycle”, a “class 2 electric bicycle”, or a “class 3 electric bicycle” as defined in this section. (ORC 4511.01(RRR))
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.
Reference evapotranspiration or “ETo” means a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in Appendix C of these Guidelines, and is an estimate of the evapotranspiration of a large field of four to seven-inch tall, cool-season grass that is well watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances.
