Examples

• The ignitability of the material was tested before it was approved for use in the building.
• Gasoline has high ignitability, which is why it must be stored carefully.
• Safety regulations require manufacturers to assess the ignitability of all fabric products.
• The ignitability of wood increases when it is dry.
• Engineers evaluated the ignitability of the new insulation material in laboratory conditions.
