What does ASTM stand for & what do they publish? - ANSWER
✔✔American Society for Testing & Materials. ASTM publishes industry
specifications for many different materials including petroleum products.
The specification for Fuel Oils is ASTM D396. This standard sets the
minimum specifications for the
fuel.
The definition of (flash point of a fuel) is what? - ANSWER ✔✔The
maximum temperature at which it can be
safely stored and handled without serious fire
,hazard (~100 F)
The definition of (ignition point) is what? - ANSWER ✔✔The lowest
temperature at which rapid
combustion of the fuel takes place in air (~500 F)
The definition of (pour point of #2 oil) is what? - ANSWER ✔✔The
lowest temperature at which oil will flow (21 F)
The pour point of #2 oil can be lowered by what two
methods? - ANSWER ✔✔It can be lowered by blending with
kerosene. It can be lowered with fuel additives (~1 F)
The viscosity is the thickness of the fuel; viscosity will change depending
on the temperature, as oil gets colder does the viscosity increase or

Bacteria, Degraded Fuel and other contaminants
What are the three basic parts of
combustion? - ANSWER ✔✔Oxygen (Air), Fuel, Ignition

three things? - ANSWER ✔✔Breaks the oil into small droplets, Mixes
the droplets with air, Allows the oil to evaporate and burn
Dirt or lint build-up in the bevel of the burner
motor fan blades will cause what? - ANSWER ✔✔It will reduce the
