NOTES

Conduction is heat transfer to another body or within a body by direct contact. (NFPA 921-2017, 3.3.38)

This video shows the conductivity of two metals: steel & copper

- The temperature of the copper pipe (measured away from the flame) rises more quickly than that of the steel.

Q: Why does the copper pipe heat up more quickly

A: -higher conductivity

Heat can transfer by conduction through walls and along copper pipes.Hot heating ducts in contact with nearby materials can cause pyrolysis of the materials (chimney fires) and, if left unchecked for long enough, can potentially lead to ignition and combustion.It is thus important to consider conduction in fire spread scenarios.
