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… WebNov 27, 2024 · Using Q (charge) = C m (capacitance) x V (voltage), the capacitance is set at the measuring distance of 100 mm. This means that the charge Q varies directly with the voltage V. Fraser meters are simple to use and very useful in analysing problems. The 715 Static Meter is ideal for non-hazardous environments. 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.
