products have been inadvertently mixed, or a product containing foreign
matter, such as dust, dirt, rust water, or emulsions.
The addition to a petroleum product of some

scale, and other petroleum products.
A hydrocarbon fuel used in diesel engines
. Diesel fuels used by
the Armed Forces are manufactured under two specifications: W-F-800 and
A device used to separate both solid contaminants
from a petroleum fuel.
flammable A term describing any combustible material which can be ignited
easily and which will burn rapidly. Petroleum products which have flash
points of 1OO, F (37.80C) or lower are classed as flammable.
flash point The lowest temperature at which a liquid petroleum product gives
off vapor in sufficient concentration to ignite (that is, flash) on
application of a flame under specified conditions.
jet fuel Fuel meeting the required properties for use in jet engines and
aircraft turbine engines. Jet fuels are procured for the Armed Forces in
several grades. The most important grades are JP-4 (low vapor pressure)
and JP-5 (high flash point), and JP-8.
A refined petroleum distillate used in space heating
wick-fed lamps, bomb-type flares, for cleaning certain machinery and
tools, and as a base for liquid insecticide sprays. A single multiple-use
type is procured under Federal Specification VV-K-21 1. A deodorized type,
which is used as a base for insecticide sprays, is procured under
Millipore test A test for particulate contaminants in fuel supplies.
petroleum Crude oil. Petroleum is a mixture of gaseous, liquid, and
semisolid hydrocarbons varying widely in gravity and complexity. Petroleum
can be removed as a liquid from underground reservoirs, and it can be
separated into various fractions by distillation and recovery. Petroleum
is a general term that includes all petroleum fuels, lubricants. and
Petroleum, Oils, and Lubricants
. Included are petroleum fuels,
lubricants, hydraulic and insulating oils, temporary protectives, liquid
and compressed gases, chemical products, liquid coolants, deicing and
antifreeze compounds, together with components and additives of such
specific gravity The ratio of the weight of any quantity of matter, a
petroleum product for example, to the weight of an equal quantity of
water; usually determined by use of a hydrometer.
