Carpet padding is typically a urethane foam, or a amalgamation of bits of scrap urethane foam bonded together. In either case it is a Group A expanded plastic.

I may be looking at trying to compare apples to oranges. The 2003 IFC calls out "Rugs without foam backing" as a Class III com. When the rugs have a foam back then it's a Class IV com. Again according to the 03 IFC. NFPA 13 states that cartoned carpet tiles are Group A plastics. I may not correctly be thinking what carpet tiles are, but to me they are nothing more than carpet with pad, that are cut up into 1x1 foot squares and installed in a similar fashion as other forms of tiles. Are rugs the same as carpet? Inherently, I say yes. The intent of my original question is to determine a commodity classification from the IFC point of view to determine requirements for a warehouse storing such commodities. The IFC does have a provision that states where differences occur between the code and a referenced standard, the code shall apply (apples and oranges). Ok. I'll buy that for a buck, but if for high pile storage purposes of the IFC, a facility is classified as a Class 3 or 4 commodity, I can see problems when the sprinkler designer and/or AHJ calls out Group A plastics or high hazard. I guess I'm trying to understand the differences in classifications between the code and standard for a seemingly same commodity. Hope my gibberish makes sense.
