Does the "a material" in the following screenshot refer to any material which is combustible or non-combustible?

Some wood elements are permitted in non combustible construction, how does wood pass a non-combustibility test?

By being so limited in quantity that it doesn't offer a significant contribution to the fuel load in a fire. The limited inclusion of wood in non-combustible construction doesn't pretend that the wood isn't combustible, it just says "Don't use too much of it and we'll allow it as decoration."
 
3.1.5. is structured to provide the testing requirements as the general rule, but then includes exceptions for other permitted items. It is likely that any of the listed exceptions would not pass the testing.
