Your video is a great help for people like me who is study by themself. Because the textbook is often quite confusing. The definition of flashpoints in Principles of Fire Behavior, Second Edition is 'At piloted ignition, the surface concentration needs only to achieve the LFL. At this concentration, the corresponding surface temperature is called the flashpoint (T_FP). ' A fuel at LFL concentration could be in a range of temperatures. This was why I was bemused before I watched this video
Regarding the autoignition demos, it seems hard to say for sure that a lick of flame didn't touch the kerosene vapours. Likewise for the flashover furniture.
That's probably fair to say. I remember back when I made this episode I was really struggling to get useable footage. I'd probably go about it a little differently now. But hopefully the concepts still hold up for you 👍🏼
