||Interlab Study Will Determine Relative Bias of Automatic vs. Manual
D 86 Distillation
ASTM D 86, Standard Test Method for Distillation of Petroleum Products
at Atmospheric Pressure, is a critical test for petroleum products
and lubricants. Developed in 2000, it provides volatility parameters
for motor and other automotive spark-ignition fuels, aviation
fuels, aviation turbine fuels, solvents, and other petroleum products.
The current relative bias of automatic vs. manual D 86 distillation
data was obtained in 1962 for diesel and kerosene, and 1982 for
gasoline. Improvements in automatic D 86 distillation technology
require an updated accurate measure of relative bias between automatic
and manual D 86 results. A task group of ASTM Committee D02 on Petroleum and Lubricants was formed to coordinate an interlab
study to determine relative bias under strict compliance with
D 86 distillation parameters.
Members of the petroleum, lubricants, and solvents industries
who use D 86 will benefit from this activity. The study has drawn
broad interest: 52 cooperatives in 13 European and North American
countries. Among the group, 38 will use automatic instruments
and 14 manual. Eight samples will be tested: summer and winter
grades of diesel fuel, jet fuel, European unleaded gasoline, Canadian
winter-grade gasoline, hexadecane; and toluene. Strict adherence
to the D 86 parameters will be required to ensure that relative
bias data is not influenced by deviations from the test method.

Dec. 2-7 in Miami Beach, Fla. For meeting or membership details,
