NFPA 13, 2016 12.6.1 For storage applications with densities of 0.2 gpm/ft2 (8.1 mm/min) or less, standard response sprinklers with a K-factor of K-5.6 (80) or larger shall be permitted.
12.6.2 For general storage applications, rack storage, rubber tire storage, roll paper storage, and baled cotton storage being protected with upright and pendent spray sprinklers with required densities of greater than 0.2 gpm/ft2 to 0.34 gpm/ft2 (8.1 mm/min to 13.9 mm/min), standard-response sprinklers with a nominal K-factor of K-8.0 (115) or larger shall be used. 12.6.3 For general storage applications, rack storage, rubber tire storage, roll paper storage, and baled cotton storage being protected with upright and pendent spray sprinklers with required densities greater than 0.34 gpm/ft2 (13.9 mm/min), standard-response spray sprinklers with a K-factor of K-11.2 (161) or larger that are listed for storage applications shall be used. 12.6.4* Unless the requirements of 12.6.5 are met, the requirements of 12.6.2 and 12.6.3 shall not apply to modifications to existing storage application systems, using sprinklers with K-factors of K-8.0 (115) or less.
