flame spread characteristic
Explanation: Be very careful here! As I understand it (and I'm NOT a specialist!), a distinction is made between fire and flame retardancy — and in your case, I think you're actually talking about the flame spread characteristics, though I'm not sure of the exact terminology here. But it gets 417 hits on Google, some at least of which seem to be relevant. Here's one that mentions it in a likely context, and may lead you to further info. Note that they are clearly making the point that this is a surface characteristic, hence why it is most important to maintain the distinction with flame propagation rather than retardancy, which is subtly but importantly different. I think your first term is a global one, and the second 2 are specific sub-cases: halogen-free and halogen-containing materials. The first can tolerate a limited flame spread (since it won't produce the same toxic gases), but the second will tolerate zero flame spread (because of toxic combustion products produced, for example) [PDF]2015 A-4 print file File Format: PDF/Adobe Acrobat ... E-84, Standard Test Method for Surface Burning Characteristics of Building Materials , was developed to rate building products for flame- spread characteristics ... Good luck!
