What is the meaning of fusion point?
The temperature at which melting takes place. Most refractory materials have no definite melting points, but soften gradually over a range of temperatures.
How is fire point determined?
13.2. The flash point is determined by heating the sample of fuel in a container and passing the flame over the surface of the sample. If the temperature is at or above the flash point, the vapor will ignite and an easily detectable flash can be observed. The flash produced need not sustain for long time.
What is kindling point or ignition point?
The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion.
What is the difference between melting point and fusion?
The changing of solid state into liquid state is fusion while the minimum temperature at which the solid state changes into liquid state at normal atmospheric pressure is called its melting point.

What is flash and Firepoint?
Fire safety includes fire signs, tags and labels from Safety Emporium. Flash point is the lowest temperature at which a liquid can gives off vapor to form an ignitable mixture in air near the surface of the liquid. The lower the flash point, the easier it is to ignite the material.
Which is more important flash point or fire point?
The fire point is the lowest temperature at which the vapors keep burning after the ignition source is removed. It is higher than the flash point, because at the flash point more vapor may not be produced fast enough to sustain combustion.
