Flash Point

Overview

Engineering reference data for Flash Point in miscellaneous.

Key Formulas

Unit Conversion

$y = x \cdot k$

Multiply by conversion factor.

Linear Interpolation

$y = y_1 + \frac{(x - x_1)(y_2 - y_1)}{x_2 - x_1}$

Estimate between two known points.

Percentage

$p = \frac{\text{part}}{\text{whole}} \times 100\%$

Part as fraction of whole.

Variables

Flash Point vs. Auto-Ignition Temperature

It is critical to distinguish between the flash point and the auto-ignition temperature of a material.

• Flash Point: The lowest temperature at which a liquid produces enough vapor to form an ignitable mixture with air near the surface of the liquid. An external ignition source (spark, flame) is required.
• Auto-Ignition Temperature: The minimum temperature required to cause self-sustaining combustion in air without an external ignition source.

Flash Point Hazard Classification

The following table classifies materials based on their flash point temperature.
