Test Method

D6278--Evaluates the shear stability of polymer-containing fluids. The test method measures the percent viscosity loss at 100°C of polymer-containing fluids when evaluated by a diesel injector apparatus procedure that uses European diesel injector test equipment. The viscosity loss reflects polymer degradation due to shear at the nozzle.

D7109—Evaluates the shear stability of polymer-containing fluids. The test method measures the viscosity loss, in mm2/s and percent, at 100°C of polymer-containing fluids when evaluated by a diesel injector apparatus procedure that uses European diesel injector test equipment. The viscosity loss reflects polymer degradation due to shear at the nozzle. Viscosity loss is evaluated after both 30 and 90 cycles of shearing.

Description

The apparatus consists of a fluid reservoir, a double-plunger pump with an electric motor drive, an atomization chamber with a diesel injector spray nozzle, and a fluid cooling vessel, installed in an area with an ambient temperature of 20 to 250C. Fluid reservoir is open on the top, has approximately a 250mL capacity, has a 45-mm inner diameter, and is calibrated in units of volume. It is fitted with an internal fluid distributor. A 40-mm diameter watch glass with serrated edges is an acceptable distributor plate. The distributor reduces the tendency of fluid channeling. Temperature is measured by a thermometer suspended in the center of the fluid reservoir. The bottom of the thermometer bulb shall be 10 to 15mm above the entrance to the drain tube opening. Other temperature measuring equipment positioned at the same location may also be used. The outlet is equipped with a three way stopcock. The three way stopcock is of a cone type with a non exchangeable solid plug with an 8-mm nominal bore size. Transparent, plastic tubing, is used to connect the three-way stopcock to the pump inlet.
