FIGURE 13.2.1 Miscellaneous Storage Up to 12 ft (3.7 m) in Height — Design Curves (see Table 13.2.1).

Installation criteria as permitted by NFPA 13 and design criteria and modifiers as permitted by the density/area method of Chapter 11 for ordinary hazard Group 1, ordinary hazard Group 2, extra hazard Group 1, and extra hazard Group 2 occupancies shall be applicable.
Where K-11.2 (160) or larger sprinklers are used with EH1 or EH2 design curves from Figure 13.2.1, the design area shall be permitted to be reduced by 25 percent but not below 2000 ft2 (186 m2), regardless of temperature rating.
In-rack sprinklers required by Table 13.2.1 shall meet the requirements of this section and the applicable storage protection and arrangement sections of this chapter.
In-rack sprinklers shall have a K-factor of 5.6 (80) or larger and operate at a minimum of 15 psi (1 bar).
Where one level of in-rack sprinklers is installed for miscellaneous storage, water demand shall be based on simultaneous operation of the hydraulically most demanding four adjacent sprinklers.
In-rack sprinklers for miscellaneous storage shall be located at the first tier level at or above one-half of the storage height.
Horizontal spacing of in-rack sprinklers shall not exceed 8 ft (2.4 m).
In-rack sprinklers shall be located in the longitudinal flue at the intersection of the transverse flues while not exceeding the maximum spacing rules.
If no longitudinal flue is provided in single- and double-row racks, in-rack sprinklers shall be located within 12 in. (300 mm) of the center of the rack while not exceeding the maximum spacing.
Where distances between transverse flues exceed the maximum allowable distances, sprinklers shall be installed at the intersection of the transverse and longitudinal flues and additional sprinklers shall be installed between transverse flues to meet the maximum distance rules.
Where no transverse flues exist, in-rack sprinklers shall not exceed the maximum spacing rules.
