Best describe a fuel flashpoint (Ponto de fugor)
The lowest temperature and vapors of fuel will keep burning.
O ponto de fulgor indica o quão fácil é para um combustível pegar fogo.
Combustíveis com ponto de fulgor mais baixos são mais perigosos, pois podem se inflamar com temperaturas mais baixas.
Best describe a fuel fire point.
É a temperatura minima na qual o combustível continua a queimar por pelo menos 5 segundos após ser aceso.
Enquanto o ponto de fulgor é a temperatura minima em que os vapores podem acender, o ponto de fogo e a temperatura em que a combustão pode ser sustentada de forma contínua.
