"All liquids have a specific vapor pressure, which is a function of that liquid's temperature and is subject to Boyle's Law. As temperature increases, vapor pressure increases. As vapor pressure increases, the concentration of vapor of a flammable or combustible liquid in the air increases. Hence, temperature determines the concentration of vapor of the flammable liquid in the air. A certain concentration of a flammable or combustible vapor is necessary to sustain combustion i… " - How do you measure flammability

WebThere are two types of flammability tests according to UL 94: horizontal and vertical, which consist of measuring the burning time of a plastic sample fixed horizontally or vertically, after it has touched the flame of a burner during the time specified in the corresponding standard. Horizontal Flammability WebDec 10, 2024 · Flammable liquids have a flash point of less than 100°F. Liquids with lower flash points ignite easier. Combustible liquids have a flashpoint at or above 100°F. The vapor burns, not the liquid itself. The rate at which a liquid produces flammable vapors depends upon its vapor pressure. The vaporization rate increases as the temperature increases.
