Introduction
The response characteristics of classic sprinklers (EN 12259-1 and EN 12259-15) is based on the
measurement of both sensitivity and conductivity (C-factor). For EN 12259-13 sprinkler type (ESFR)
their response characteristics are determined without reference to its conductivity.
1 Scope
This document specifies requirements and test methods for spray pattern sprinklers with a k-factor of at
least K160, extended coverage (EC) sprinklers of at least K80, extended coverage storage sprinklers of at
least K200 and control mode special application (CMSA) sprinklers. This document only covers sprinkler
types up to K360.
This document does not apply to concealed, conventional, flat spray, flush and recessed sprinklers.
