Why does NFPA 13 limit the use of ESFR sprinklers in storage occupancies to 46 feet (14 meters)?
Looking for some next-level insight here.

If I had to venture a guess:

Agree NPFA testing is the limiting factor.

TL;DR: Fire Testing.

That is the highest they have performed full scale testing. Also, the highest roof deck / ceiling height I have seen in NFPA 13 is 45 ft.

It is simply because that was the height of the ceiling of the testing facility.

For storage applications there are too many scenarios that ceiling level sprinklers would need to be tested and approved. Consult a specific manufacturer for limits on their specific sprinklers.

Typically because no one has submitted inputs with revised or added language and testing backup to be considered/added to NFPA and this is likely due to the larger, accredited test facilities not being tall enough to test above that height.

Anthony, Paul & Dan gave the most important reasons : Ceiling height of the testing facility and droplet size/penetration.

Manufacturers pay the cost of testing their particular products through independent testing labs.

It has everything to do with listing. And listing has everything to do with testing.

Well said Jesse. I run into similar questions on watermist systems.

I have a hotel... and in the pool area the ceiling is 30 high...

It depends upon the fuel for the fire. Obviously, the pool will not burn, but materials around the pool will.
