As I recall, the chemical that was described is what is sold in the US as kerosene. It appeared way back in the early UL standards that way. Since this is a petroleum distillate characterized mainly by its molecular weight and what temperature it comes off the refining process, describing it is kind of like coming up with a chemical formula for milk. Too messy to try. The term kerosene was not sufficient to properly describe it worldwide, so this description was what was recommended by those in the business. Many have also used cigarette lighter fluid for the test. Functionally it is pretty equivalent, just a lighter distillate. The container's much more convenient.
