Requirements for installation and use of ESFR sprinklers are includ
28、ed in the Standard for the Installation of Sprinkler Systems, NFPA 13, as well as other NFPA standards. 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 the Standard for the Installation o
29、f Sprinkler Systems, NFPA 13, that are intended to provide protection for specic re hazards. 2 Components 2.1 Except as indicated in 2.2, a component 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 r
30、equirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be used in accordance with its rating established for the intended condition
31、s of use. 2.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 3 Un

34、. 5.2 ACTUAL DELIVERED DENSITY (ADD) The rate at which water, discharged from a sprinkler, is actually deposited onto the top of the protected horizontal surface under a re condition. 5.3 ASSEMBLY LOAD The extension force applied to the sprinkler frame by the assembly of its operating mechanism. 5.4
35、 DELIVERED DENSITY The rate at which water, discharged from a sprinkler, is actually deposited onto the top of the protected horizontal surface under a nonre condition. 5.5 DISCHARGE COEFFICIENT K Coefficient of discharge in the formula: in which: Q is the ow in gallons per minute; and p is the pres
36、sure in pounds per square inch gauge. In SI units: Q is the ow in liters per minute; and p is the pressure in bar 5.6 DRY-TYPE SPRINKLER A sprinkler secured in an extension nipple that has a seal at the inlet end to prevent water from entering the nipple until the sprinkler operates. Note: Dry-type
37、ESFR sprinklers are intended for use on wet systems only since ESFR sprinklers are not intended for use in dry systems as referenced in NFPA 13. 5.7 EARLY SUPPRESSION A characteristic of sprinkler performance whereby the rst few operating sprinklers are able to deliver sufficient water to the re to
