While the reasoning MIGHT be true has anyone shown data through fire tests or actual fires that the reasoning IS true?

There was no allowance for EC spacing in some cases. Craig L.

If anyone's familiar with this particular version of it I have a quick question: Ordinary Hazard group-1 is the minimum design allowed but they do give a couple exceptions. One is that QR & QREC heads listed for light hazard are permitted as long as OH-1 density is still achieved. What would be the benefits of applying this exception? Thanks!
