This test method covers the detection of wax in burner fuels, diesel fuels, and turbine engine fuels in the range from -26 to +2°C. It is applicable to a dark-colored oil if the stirrer can be seen under illumination.

This test method is being balloted for withdrawal with no replacement because the test method is no longer in use, and there is no report from the CS92 ILCP.

Formerly under the jurisdiction of Committee D02 on Petroleum Products and Lubricants, this test method was withdrawn in May 2010.

Wax appearance point is the temperature at which wax crystals begin to precipitate out of a fuel under specified cooling conditions. The presence of wax crystals in the fuel may restrict flow or plug the fuel filter. In critical fuel systems, wax appearance point may define the lower limit of acceptable operability.

1.1 This test method covers the detection of wax in burner fuels, diesel fuels, and turbine engine fuels in the range from -26 to +2°C. It is applicable to a dark-colored oil if the stirrer can be seen under illumination.
