Tight-fitting facepiece means a respiratory inlet covering that forms a complete seal with the face.
Semiconductor cleanrooms means the integrated systems, fixtures, piping, partitions, flooring,
explosive actuated fastening device means a tool that is activated by an explosive charge and that is used for driving bolts, nails and similar objects for the purpose of providing fixing;
Nitrogen oxides means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO2);
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.
Polystyrene foam adhesive means an aerosol adhesive designed to bond polystyrene foam to substrates.
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]
Vapor tight means equipment that allows no loss of vapors. Compliance with vapor-tight requirements can be determined by checking to ensure that the concentration at a potential leak source is not equal to or greater than 100 percent of the lower explosive limit (LEL) when measured with a combustible gas detector, calibrated with propane, at a distance of 1 inch (2.54 cm) from the source.
Fiber means a glass strand or strands which is/are protected by a color coded buffer tube and which is/are used to transmit a communication signal along the glass strand in the form of pulses of light.
Beam scattering foil means a thin piece of material (usually metallic) placed in the beam to scatter a beam of electrons in order to provide a more uniform electron distribution in the useful beam.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which (1) a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and (2) 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.
Polystyrene foam means blown polystyrene and expanded and
Aerosol coating product means a pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application, or for use in specialized equipment for ground traffic/marking applications.
Anaerobic digester means a liquid manure storage area that is constructed with the intent to capture and combust gas emissions resulting from the digestion of waste by microbes in anaerobic conditions. An anaerobic digester is a LMSA and is required to comply with all requirements applicable to LMSAs. Requirements specific to anaerobic digesters will be noted when applicable.
Biodegradable means degradable through a process by which fungi or bacteria secrete enzymes to convert a complex molecular structure to simple gasses and organic compounds.
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.
Glass cleaner means a cleaning product designed primarily for cleaning surfaces made of glass. Glass cleaner does not include products designed solely for the purpose of cleaning optical materials used in eyeglasses, photographic equipment, scientific equipment and photocopying machines.
Geothermal fluid means water in any form at temperatures greater than 120
Defoliant means any substance or mixture of substances intended for causing the leaves or foliage to drop from a plant, with or without causing abscission.
Loose-fitting facepiece means a respiratory inlet covering that is designed to form a partial seal with the face.
Halogen means one of the chemical elements chlorine, bromine or iodine.
Hydrofluorocarbons means compounds that only contain hydrogen, fluorine, and carbon.
High-temperature coating means a high performance coating labeled and formulated for application to substrates exposed continuously or intermittently to temperatures above 204oC (400oF).
Lightweight means the displacement of a ship in metric tons without cargo, fuel, lubricating oil, ballast water, fresh water and feed water in tanks, consumable stores, and passengers and crew and their effects.
CO2 means carbon dioxide.
Electrical Fitter means an employee who is mainly employed in the workshops manufacturing, fitting, and repairing electrical instruments, machines, and apparatus. Electrical fitting in this definition shall include armature and transformer winding, and people solely engaged in making and repairing instruments. The legitimate possession of a certificate of competency in this particular class of work issued by the Electrical Licensing Board under the Electricity Act 1994 shall be recognised as proof of efficiency.
