ASTM D6751 – Biodiesel Fuel
Blend Stock (B100) for Middle
Distillate Fuels
Biodiesel fuel blend stock (B100) is comprised of mono-alkyl esters of long
chain fatty acids derived from vegetable oils or animal fats. Biodiesel fuel is
normally produced from a reaction between vegetable oil or animal fat and
methanol or ethanol in the presence of a catalyst to produce mono-alkyl
esters and glycerin, which is removed. The biodiesel product attributes
approximately 10% of its mass from the reacted alcohol.
For biodiesel fuels to conform to the specifications of ASTM D6751, they are
required to pass the following test methods. Click the test methods below for
more information.

ASTM D93 – Flash Point by Pensky-Martens Closed Cup Tester
Determines the flash point of biodiesel samples within the temperature range of
140 to 374°F (60 to 190°C). Pensky-Martens Closed Cup Flash Tester determines
the ignition point of fuels with a closed cup method by stirring the sample with
AS TM D93
two speed options. Flash point tests are used in shipping and safety regulations for
detecting contaminants by volatile and flammable materials in biofuel samples.
Flash point: The lowest temperature at which the vapors of a sample ignite.
Manual Flash Point Testers
Adjustable heater provides excellent accuracy
Pensky-Martens closed-cup flash testers are used to determine the flash point of fuels,
lubricating oils, liquids containing suspended solids, and liquids that tend to form a surface
film during testing.
They feature a cover that slides the shutter open to apply test flame. Select from electrical
or gas heated models. Electrical models are equipped with a 750 watt nickel-chromium
heater. Gas model has a built-in nickel-plated brass natural gas burner and liquid propane
burner mounted on a cast iron base.
What’s included: thermometer holder, brass test cup with handle, pilot flame, test flame
reference bead, built-in stirrer, plated brass thermometer ferrule, and cooling vents. Order
stirrer motor separately below.

ASTM D2709 – Water and Sediment in
Middle Distillate Fuels by Centrifuge
Centrifugation provides a means of determining the volume of water content and
sediment in a sample of biodiesel with viscosity between 1.0 to 4.1 mm
4.1 cSt) and densities between 770 to 900 kg/m
3
at 104°F (40°C). The Automatic
Heated Oil Test Centrifuge separates the layers of the biodiesel sample by density
to determine the amount of water content and sediment within the sample. High
volumes of water in the oil have the potential to cause system corrosion. Sediment
in the oil obstructs the flow of the biodiesel.

Automatic Heated Oil Test Centrifuges
Fully automatic benchtop unit is designed expressly for petroleum testing applications
■
Automatic control of acceleration ramp, centrifugation speed,
and timing functions
■
Doubly insulated to reduce heat loss and increase reproducibility
■
Sliding stainless steel lid with large clear top to view your samples
■
Group D, Class 1, Division 2 explosion-resistant rating
This oil test centrifuge is used for water and sediment determination and
is fully automated. Use the integrated 4
to set test duration, the RCF and rpm values, and choose your specific
rotor assembly and its corresponding glassware. You may set the unit
to your desired speed. Quiet running unit features an elastic suspension
of the drive motor for self-balancing operation. The operating speed will
remain constant due to the voltage compensated circuitry in the event of
voltage fluctuations.
Molded PTFE cushions provide excellent chemical resistance, ease of
tube positioning, and longevity of your unit. View your samples while
they are spinning from the clear 18
the lid. The lid allows easy access to the rotor and tube holders for
easy cleaning. Unit is equipped with a safety lockout mechanism and
automatic electronic braking system.
What’s included: rotor assembly and power cord.
