LESSON 1
PRACTICE EXERCISE
The following items will test your knowledge of the material covered in this lesson. There is only one correct
answer for each item. When you complete the exercise, check your answers with the answer key that follows. If
you answer any items incorrectly, go back to the part of the lesson that contains the information involved and
study again.
1. When conducting ASTM D-95, standard test procedure for water in petroleum products and bituminous
materials by distillation, what formula is used in calculating and reporting the procedure?
A. Mass % = ______mass sediment x 100.
B. Olefins, % volume = (Lo/L) x 100.
C. Water, % = V/W x 100.
D. Qp1 = G - A + (G x V).
2. What is the significance of ASTM D-473?
A. A knowledge of the water content of petroleum products is important in the refining, purchase, sale, and
transfer of products.
B. A knowledge of the sediment content of crude oil and fuel oils is important both to the operation of
refining and the buying or selling of the oil.
C. This test method provides an indication of the relative smoke producing properties of kerosene and
aviation turbine fuels in a diffusion flame.
D. A knowledge of this test method is a guide in cases where experimental determination of heat of
combustion is not available and cannot be made easily and where an estimate is more satisfactory.
3. When conducting ASTM D-1319, standard test method for hydrocarbon types in liquid petroleum products by
fluorescent indicator adsorption, where should you stand when attaching the filled column to the apparatus
assembly?
A. In a sunny area.
B. Outdoors for proper ventilation.
C. In a darkened room or area.
D. Next to a fire extinguisher.
4. What comprises the apparatus for ASTM D-1322?
A. Glass or metal still, heater, reflux condenser, and graduated glass trap.
B. Extraction apparatus, extraction flask, condenser, extraction thimble, thimble basket, water cup, and
source of heat.
C. Apparatus for this test method is not required because it consists of correlating observations.
D. Smoke point lamp, wick, and pipettes or burettes.
5. What makes up the sampling requirements for ASTM D-3338?
A. Correlating various equations and formulas and substituting values relating to various fuels into the
equations.
B. Aviation turbine fuel and kerosene, boiling between 140 and 300C, generally used in lighting and
heating applications.
C. The size of the test portion should be based on the expected water content of the sample, such that the
water yield does not exceed the capacity of the trap.
D. Get a sample according to procedures in practice D-4057.
