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 for the protection of any of the following:

1. Miscellaneous storage as described by Table 13.2.1
2. Commodity Class I through Class IV storage 12 ft (3.7 m) or less in height as directed by 14.2.3.1 and 16.2.1.2.1
3. Storage of Group A plastics up to 5 ft (1.5 m) in height as directed by 15.2.1 and 17.2.1.1

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.
