Pressure means relative pressure versus atmospheric pressure, unless otherwise stated.
True vapor pressure means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute (API) Bulletin 2517, Evaporation Loss from External Floating Roof Tanks, 1980. The API procedure may not be applicable to some high viscosity or high pour crudes. Available estimates of true vapor pressure may be used in special cases such as these.
Vapor pressure as herein used means Vapor Pressure at 100° Fahrenheit as determined by ASTM Method D-323-90, "Standard Method of Test for Vapor Pressure of Petroleum Products (Reid Method)."
Noise means two times the root mean square of ten standard deviations, each calculated from the zero responses measured at a constant frequency which is a multiple of 1,0 Hz during a period of 30 seconds.
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.
Operating pressure means the pressure at which the parts of an irrigation system are designed by the manufacturer to operate.
Pressure vessel means a vessel that may be used for containing, storing, distributing, transferring, distilling, processing or otherwise handling any gas, vapour or liquid under pressure greater than the atmospheric pressure and includes any pipeline fitting or other equipment attached thereto or used in connection therewith; and
Ventilation means the supply of outside air into a building through window or other openings due to wind outside and convection effects arising from temperature, or vapour pressure differences (or both) between inside and outside of the building;
design pressure means the maximum pressure that a pressure vessel or plant is designed to withstand safety when operating normally;
Potential electrical output capacity means, with regard to a unit, 33 per- cent of the maximum design heat input of the unit.
Working pressure means pressure, in a working chamber, to which building worker is exposed;
Sanitary with respect to a building, means it is free from danger or hazard to the health of persons occupying or frequenting it or to that of the public, if such danger arises from the method or materials of its construction or from any equipment installed therein, for the purpose of lighting, heating, ventilating, or plumbing.
Meters shall have the meaning set forth in Section 4.6(a) hereof.
Load means energy consumed by Customers together with allocated losses and unaccounted for energy;
Sanitary Sewer System means all facilities, including ap- proved LOSS, used in the collection, transmission, storage, treatment, or discharge of any waterborne waste, whether domestic in origin or a combination of domestic, commercial, or industrial wastewater. LOSS are only considered sanitary sewer systems if they are designed to serve urban densities. Sanitary sewer system is also commonly known as public sewer system.
Density means the permitted number of dwelling units per
Sewer System means pipelines or conduits, pumping stations, force mains, vehicles, vessels, conveyances, injection wells, and all other constructions, devices, and appliances appurtenant thereto used for conducting sewage or industrial waste or other wastes to a point of ultimate disposal or disposal to any water of the state. To the extent that they are not subject to section 402 of the federal Water Pollution Control Act, ditches, pipes, and drains that serve only to collect, channel, direct, and convey nonpoint runoff from precipitation are not considered as sewer systems for the purposes of this part of this division.
Boiler means an enclosed fossil or other fuel-fired combustion device used to produce heat and to transfer heat to recirculating water, steam, or other medium.
Low water pressure means water pressure below the regulatory reference level which is the minimum pressure when demand on the system is not abnormal.
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.
voltage means the root-mean-square value of electrical potential between two conductors.
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]
Trash means solids not considered to be highly flammable or explosive including, but not limited to clothing, rags, leather, plastic, rubber, floor coverings, excelsior, tree leaves, yard trimmings and other similar materials.
Drainage means the movement of water to a place of disposal, whether by way of the natural characteristics of the ground surface or by artificial means;
Heat input means the product (expressed in mmBtu/time) of the gross calorific value of the fuel (expressed in Btu/lb) and the fuel feed rate into the combustion device (expressed in mass of fuel/time) and does not include the heat derived from preheated combustion air, recirculated flue gases, or ex- haust from other sources.
Vessels shall have the meaning set forth in the recitals.
