FYI, if it is a retrofit, you are not specifically tied to 12.6.2 and 12.6.3 with sprinklers of K-11.2 or greater. The following Subsection 12.6.4 is an "exception" to those provisions:
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. A.12.6.4 Modification of an existing system includes extending sprinkler protection into adjacent areas. With this, EOR call ups not-with-standing, NFPA 13-2013 allows you to utilize any K sprinkler that works for you hydraulically. The foregoing is my opinion only and does not represent NFPA or the NFPA 13 Technical Committees.

I have an EOR that called for a K14.0 CMDA on a specific job. Since I can't find one, I was wondering if I could use a K11.2 instead. Brian Harris, CET BVS Systems Inc. bvssytemsinc.com<http://bvssystemsinc.com/> From: Eric Rieve <[email protected]<mailto:[email protected]>> Sent: Monday, September 11, 2023 11:48 AM To: Discussion list on issues relating to automatic fire sprinklers <[email protected]<mailto:[email protected]>> Subject: [Sprinklerforum] Re: CLASS I-IV / CMDA Brian, To expand on this slightly, it's not that "general storage applications" directly means class I-IV commodities, but that chapter 12 applies to all the following storage criteria chapters. So, "general storage applications" is how they show that 12.6.3 applies to chapters 14 and 15 for solid-piled commodities, and then "rack storage" is there to reference chapters 16 and 17. The rest of the sentence containing "rubber tire storage, roll paper storage, and baled cotton storage" is how they reference chapters 18, 19, and 20 respectively to round out the rest of chapters. [A close up of text] Hope this helps!
