18、tions, such as certain temperatures notexceeding specified limits, and shall be used only under those specific conditions.3 Units of Measurement3.1 The metric unit shall be designated as the official unit for purposes of this standard. Where values ofmeasurement are specified in both SI and English

19、units, either unit is used. In cases of dispute, the metricunit shall be used.AUGUST 24, 2016 UL 1384 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL4 Undated References4.1 Any undated reference to a code or standard appearing in the require

21、r a gas cartridge pressurized with an inert gas that includes a puncture disc, whichupon automatic means of actuation, releases pressure resulting in the discharge process.5.3 AUTOMATIC EXTINGUISHER UNIT A unit that has no manual means of actuation and dischargesextinguishing agent upon thermal actu

22、ation, and is intended for use in a normally unoccupied space andis limited to a single protected area.5.4 CYLINDER/VALVE ASSEMBLY A container that incorporates a valve and that provides storage ofthe extinguishing agent and expellant gas until the valve is actuated. For cartridge operated units, th

23、isassembly includes the dry chemical storage container and cartridge mechanism. When actuated, thevalve releases the agent into the distribution network of the extinguisher unit.5.5 DISCHARGE NOZZLE A device that is used to uniformly distribute the extinguishing agent over orinto a specific area, or

24、 within a specific volume, or both.5.6 DISCHARGE RATE The ratio of the quantity of agent discharged from a nozzle to the dischargetime measured within 1 second. When a minimum discharge rate is indicated, reference is made to theminimum quantity of agent discharged and the time measured within 1 sec

25、ond.5.7 DISCHARGE TIME The time interval between the first appearance of extinguishing agent at thenozzle and the time at which the discharge becomes predominantly gaseous.5.8 EXPELLANT GAS Dry nitrogen, dry air, or other gas used to facilitate the discharge of theextinguishing agent.5.9 GAS CARTRID

26、GE A container that provides storage for an expellant gas.5.10 HEPTANE A commercial grade hydrocarbon used as a test fuel with the following characteristics:a) Minimum Initial boiling point 88C (190F),b) Maximum Dry point 100C (212F), andc) Specific gravity (60F/60F) (15.6C/15.6C) 0.69 0.73.5.11 MET

29、omaticextinguisher unit is intended to be operated.5.14 OPERATING TEMPERATURE RANGE The temperature range inclusive of the minimum andmaximum temperatures for which the automatic extinguisher unit is intended to be stored, used, andoperated.5.15 PRESSURE VESSEL (CYLINDER) A container that provides s

30、torage for dry chemicalextinguishing agent and expellant gas, or when used at a location remote to the extinguisher unit, providesstorage for expellant gas.5.16 PROOF TEST PRESSURE The factory test pressure of each cylinder used to evaluate cylinderleakage and construction integrity. For Department

31、of Transportation (DOT) approved cylinders, thefactory test pressure is specified in the appropriate DOT specification. For ASME vessels the factory testpressure is specified in Section VIII, Pressure Vessels of the ASME Boiler and Pressure Vessel Code. Fornon-DOT cylinders and non-ASME cylinders, t

32、he factory test pressure is at least three times the cylinderoperating pressure at 70F (21C).5.17 PROTECTED VOLUME For fire tests, the volume within the protected enclosure, minus thevolume of any permanent impermeable building elements within the enclosure.5.18 TOTAL FLOODING Discharge an extinguis

33、hing agent into and throughout an enclosed space toachieve a uniform distribution of the extinguishing agent.5.19 WATER-BASED EXTINGUISHING AGENT A fire-extinguishing medium consisting of water andadditives to enhance performance.CONSTRUCTION6 General6.1 After discharge of the extinguishing agent is

34、 initiated, an automatic extinguisher unit shall maintain themaximum rate of application of extinguishing agent without requiring a manual action.6.2 All exposed parts of an automatic extinguisher unit and automatic extinguisher unit, including thefinishes on coated or painted parts, nameplates as s

35、ecured in place, attachments such as mountingbrackets required for installation, assemblies of moving parts, or other similar parts, shall be resistant tocommonly encountered atmospheric corrosive influences, and to galvanic corrosion, as determined by theSalt Spray Corrosion Test.6.3 When the deter
