Class "E" ???

[cda]

Any one have a NFPA standard and section reference for "Class E" or Class "D" ?????

For the purpose of applying flame spread limits to interior finish material, NFPA Standard No. 101 – The Life Safety Code groups flame spread ratings into five classes:

•Class A flame spread rating 0-25

•Class B flame spread rating 26-75

•Class C flame spread rating 76-200

•Class D flame spread rating 201-500

•Class E flame spread rating over 500

I've looked through Chapter 10 of the 2012 NFPA 101 and I don't see the Class D or E referenced. I'm only seeing Class A, B and C within the Chapter. It does reference NFPA 701 for the testing procedures.

It is just a question that came up in casual conversation

It's probably not mentioned in the IBC or NFPA 101 because such a rapid flamespread is unsafe in buildings.
