5.3 ASSEMBLY LOAD – The extension force applied to the sprinkler frame by the assembly of its operating mechanism. 5.4 AUTOMATIC SPRINKLER – A sprinkler intended to open automatically by operation of a heat- responsive element that maintains the discharge orifice closed by means such as the exertion of pressure on a cap (button or disc). A sprinkler is installed on piping so that a spray of water is discharged in a specific pattern for suppression or control of fires. 5.5 CEILING SPRINKLER – See Concealed Ceiling Sprinkler (5.7), Flush Ceiling Sprinkler (5.18) and Recessed Ceiling Sprinkler (5.28). 5.6 COATED, PAINTED, OR PLATED SPRINKLER – A sprinkler that has factory applied coatings, paint, or platings for corrosion protection or decorative purposes. 5.7 CONCEALED CEILING SPRINKLER – A sprinkler assembly having a cover plate. 5.8 CONTROL MODE DENSITY AREA (CMDA) STORAGE SPRINKLER FOR STANDARD COVERAGE AREAS – A sprinkler intended to be installed using standard coverage areas and density/area criteria referenced in NFPA 13. 5.9 CONTROL MODE SPECIFIC APPLICATION (CMSA) STORAGE SPRINKLER – A sprinkler intended for the protection of stored commodities as referenced in NFPA 13 or the end use limitations specified for the product. 5.10 CONVENTIONAL (OLD STYLE) SPRINKLER – A sprinkler intended for installation in the upright or pendent position, that directs from 40 to 60 percent of the total water initially discharged in the downward direction.
5.14 EXTENDED COVERAGE SPRINKLER INTENDED FOR LIGHT HAZARD OCCUPANCIES (ECLH) – A sprinkler having a specified area of coverage which is larger than the standard sprinkler coverage areas and is intended for use in light hazard occupancies described in NFPA 13. 5.15 EXTENDED COVERAGE SPRINKLER INTENDED FOR ORDINARY HAZARD OCCUPANCIES (ECOH) – A sprinkler having a specified area of coverage which is larger than the standard sprinkler coverage areas and is intended for use in ordinary hazard occupancies described in NFPA 13. 5.16 EXTENDED COVERAGE CONTROL MODE DENSITY AREA (CMDA) STORAGE SPRINKLER – A sprinkler intended to be installed using the extended coverage area and density/area criteria referenced in NFPA 13. 5.17 FLOW CONTROL (FC) SPRINKLER – A sprinkler that is intended to control water flow by automatically cycling open and closed within a specified temperature range. 5.18 FLUSH CEILING SPRINKLER – A sprinkler in which all or part of the body is mounted above the lower plane of the ceiling (or beyond a wall for sidewall sprinklers), but all of the heat responsive collector is below the lower plane of the ceiling (or beyond a wall for sidewall sprinklers). 5.19 HEAT RESPONSIVE ELEMENT – That portion of a sprinkler that breaks, melts, or otherwise functions to initiate the automatic operation of the sprinkler when exposed to sufficient heat. 5.20 HEPTANE – Commercial grade heptane having the following characteristics: a) Minimum Initial Boiling Point of 190°F (88°C); b) Maximum Dry Point of 212°F (100° C); and c) Specific Gravity (60°F/60°F) (15.6°C/15.6°C) of 0.68 – 0.73.
5.29 RESIDENTIAL SPRINKLER – A sprinkler intended to be installed in residential occupancies. 5.30 RESPONSE TIME INDEX (RTI) – A measure of the thermal sensitivity of the sprinkler’s heat responsive element. 5.31 SIDEWALL SPRAY SPRINKLER – A sprinkler intended for installation on or near the wall and near the ceiling, and designed to discharge most of the water away from the nearby wall with a small portion of the discharge directed at the wall behind the sprinkler. 5.32 SPECIFIC APPLICATION SPRINKLERS – A sprinkler intended for a limited end use such as for protecting windows, combustible concealed spaces or attics. 5.33 SPRAY SPRINKLER (STANDARD) – A sprinkler intended for installation in either the upright or pendent position respectively, designed to distribute water downward in an umbrella-shaped pattern. The discharge from a spray sprinkler having a nominal 5.6 (80) “K” factor covers a circle 16 feet (4.88 m) in diameter, 4 feet (1.22 m) below the sprinkler, when the sprinkler is discharging water at the rate of 15 gallons per minute (57 L/min). See 10 Pan Distribution Test, 54.3. 5.34 STANDARD FIRE TEST COMMODITY – CARTONED GROUP A PLASTICS (UNEXPANDED) – Single wall corrugated cardboard cartons measuring a nominal 21 by 21 by 20.5 inches high (0.53 by 0.53 by 0.52 m) containing 125 crystalline polystyrene cups in separate compartments within the carton. Single wall corrugated cardboard sheets are used to separate the five layers of cups and interlocking single wall corrugated cardboard vertical dividers are used to separate the 25 cups in each layer. Eight of the cartons are arranged in a 2 x 2 x 2 array with the open end of the cups facing down and placed on a nominal 42 by 42 by 5 inches high (1.1 by 1.1 by 0.13 m) two-way hardwood pallet.UL 199-2020 pdf download.
