28、r installation on sprinkler systems for re-protection service. Requirements for the installation and use of residential sprinklers are included in the Standards for the Installation of Sprinkler Systems, NFPA 13, and Installation of Sprinkler Systems in One- and Two-Family Dwellings and Mobile Homes
29、, NFPA 13D, and Residential Occupancies up to and Including Four Stories in Height Sprinkler Systems, NFPA 13R. 1.2 The requirements in this standard are not intended to restrict the application of representative re and other tests for special sprinklers, as referenced in Standard for the Installati
30、on of Sprinkler Systems, NFPA 13, that are intended to provide protection for specic re hazards. 1.3 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of re or of ele
31、ctric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conict with s
32、pecic requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard. 2 Components 2.1 Except as indicated in 2.2, a compone
33、nt of a product covered by this standard shall comply with the requirements for that component. 2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard,
34、or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for
35、 use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions.

36、UTION WITHOUT PERMISSION FROM UL 3 Units of Measurement 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 4 Undated References 4.1 Any undated reference to a code or standard appearing in the requirements of this standard sha
37、ll be interpreted as referring to the latest edition of that code or standard. 5 Glossary 5.1 General 5.1.1 For the purpose of this standard the following denitions apply. 5.1.2 DISCHARGE COEFFICIENT K Coefficient of discharge in the formula, Q=K p where: Q is the ow in gallons per minute, and p is
38、the pressure in psig. In SI units: Q is the ow in liters per minute; and P is the pressure in bar 5.1.3 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. 5.1.4 HEPTANE C
39、ommercial grade heptane having the following characteristics: a) Minimum Initial Boiling Point of 190F (88C); b) Maximum Dry Point of 212F (100C); and c) Specic Gravity (60F/60F) (15.6C/15.6C) of 0.68 0.73. 5.1.5 OPERATING TEMPERATURE The temperature at which the heat responsive element of a sprinkl
40、er operates when subjected to a 1F (0.5C) per minute temperature rise while immersed in a liquid bath. 5.1.6 ORIFICE The opening that controls the amount of water discharged from a sprinkler at a given pressure. 5.1.7 RESIDENTIAL SPRINKLER A sprinkler intended to be installed in residential occupanc
41、ies and that opens automatically by operation of a heat-responsive releasing mechanism that maintains the discharge orice closed. Upon operating at a specied temperature, a discharge of water is distributed in a specic pattern and quantity over a designated area. MAY 15, 2017 RESIDENTIAL SPRINKLERS

43、he lower plane of the ceiling. 5.2.2 COATED, PAINTED, OR PLATED SPRINKLER A sprinkler that has factory applied coatings, paint, or platings for corrosion protection or decorative purposes. 5.2.3 CONCEALED CEILING SPRINKLER A sprinkler assembly having a cover plate. 5.2.4 DRY-TYPE SPRINKLER A sprinkl
44、er secured in an extension nipple that has a seal at the inlet end to prevent water from entering the nipple until the sprinkler operates. These sprinklers may consist of a pendent, sidewall, ceiling or other types. 5.2.5 PENDENT SPRINKLER A sprinkler intended to be installed so that its deector is
45、located below the orice and the water ows downward through the orice. 5.2.6 RECESSED SPRINKLER A sprinkler assembly in which all or part of the sprinkler body or frame, other than the shank thread, is mounted within a recessed housing. 5.2.7 SIDEWALL SPRINKLER A sprinkler intended for installation o
46、n 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. 5.2.8 UPRIGHT SPRINKLER A sprinkler intended to be installed so that its deector is located above the orice
47、and the water ows upward through the orice. CONSTRUCTION 6 General 6.1 A residential sprinkler shall be constructed to effect closure of its water seat for extended periods of time without leakage and to open as intended and release all parts as specied in this standard. The closure of the water sea
48、t shall not be achieved by the use of a dynamic O-ring or similar seal (an O-ring or similar seal that moves during operation or is in contact with a component that moves during operation). 6.2 For dry-type pendent and sidewall residential sprinklers, the connection of the extension nipple to the se
49、al assembly at the inlet shall be airtight. See Dry Sprinkler Air Tightness Test, Section 24. 6.3 A sprinkler shall be chemically or mechanically staked to maintain the manufacturers assembly load. The assembly load shall be incapable of being changed by the use of common hand tools without causing visible damage to the sprinkler. 6.4 Stampings shall show no cracking or splitting and shall be uniformly smooth and clean cut. 6.5 The operation and distribu
