Which American code contains fire resistance of materials?

[tmgczb]

Like sandwich panel, 100mm THK, filled with mineral wool, 100kg/m3, the fire resistance is 0.8 hour.
Similarly, for clay brick wall, 240mm THK, considering plaster at both sides, fire resistance is 8 hours.

There is mention of materials of construction in the NFPA codes.

That would be crazy to include in a code, since new products are constantly created. The NFPA is concerned about the final result, regardless of material. It's up to the manufacturer to test and certify that their material meets the NFPA requirements. When I got my house reroofed, every material I looked at would have a fire resistance rating for embers landing on the roof, etc.

I can do absolutely anything. I'm an expert!

Building codes specify "required fire protection rating".

A web search for fire rated assembly details will bring up construction details that have been tested by third party testing laboratories (UL and FM for example).
