b. Generating, handling, and evaluating interface mixtures.
c. Receiving batches into tanks.
d. Verifying product quality.

Characteristics of Petroleum Products.
a. Many specialized petroleum products are developed by the military services to ensure adequate
performance of complex and highly specialized military equipment. Hence, each petroleum product is designed
or formulated to have certain characteristics. These characteristics can be physical, how the substance acts by
itself or chemical, how the substance reacts with other substances. An example of a physical characteristic is
density, and an example of a chemical property is corrosiveness.
b. Chemical and physical characteristics can be farther broken down into five categories. These five
categories are the main areas of interest in which petroleum products are tested.
(1) Volatility. Volatility is a measure of the tendency of a liquid to change to the vapor state; such as
water changing into steam.
(2) Viscosity. Viscosity is a measure of the resistance of a liquid, or semiliquid, to movement. The
higher the viscosity the more resistance to movement. For example: molasses moves slowly and has a high
viscosity; water moves quickly and has a low viscosity.
