ignitability
Ease of combustion
Ignitability is how readily something catches fire or can be set alight.
The term appears in technical contexts—fire safety, hazardous materials classification, and building codes: The ignitability of the insulation material failed to meet standards.
Materials are rated by ignitability to assess fire risk.
