Under no conditions should metal cleaning tools be brought into satm with the instrument. Calibration Procedure for Ford Cups X1.

A percent correction can be applied to the seconds? Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Temperature of Testing 8.

Fill the cup with the prepared specimen. If the ratio of shear stress to shear rate is not constant, the liquid is nonNewtonian. A small change in diameter of the ori? The frequency of this calibration check depends upon the amount of use and the care that the individual cup receives.


Originally approved in Precision and Bias Box 16, State College, Pa. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus may be used. Care of Cup If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D should be used.

Make the viscosity determination at the end of the min period.

Temperature drift during the test should be kept to a minimum and should not exceed Last previous edition approved in as D — 94 Bring this cup and the liquid viscosity standard to a constant temperature as close as possible to ASTM D 2. Allow to stand undisturbed for 10 min while adjusting further to the desired temperature.

Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus. Keep the temperature drift to within Oils available from other sources, having known kinematic viscosities, may also be used.

This standard has been approved for use by agencies of asstm Department of Defense. In addition, temperature measuring devices such as non-mercury liquid-in-glass thermometers, thermocouples, or platinum resistance thermometers that provide equivalent or better accuracy and precision, that aztm the temperature range for thermometer 17C and 17F, may be used.
