Determine the time of efflux to the nearest 0. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Individual reprints axtm or 1d200 copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Calibration Procedure for Ford Cups X1. If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D should be used.
This standard has been approved for use by agencies of the Department of Defense.
In d2100, 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 cover the temperature range for thermometer 17C and 17F, may be used. Last previous edition approved in as D — 94 Permission rights to photocopy the standard may also be secured from the ASTM website www. A percent correction can be applied to the seconds?
A small change in diameter of the ori? For particular oils applicable for use with the Ford Cups refer to Table X1. Box 16, State College, Pa. NOTE 1—If the ori? Allow to stand undisturbed for 10 min while adjusting further to the desired temperature. Temperature of Testing 8. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus may be used. Summary of Test Method 4. ASTM D 2.

Particular care must be exercised in cleaning the ori? Make the viscosity determination at the end of the min period. The frequency of this calibration check depends upon the amount of use and the care that the individual cup receives.
Bring this cup and the liquid viscosity standard to a constant temperature as close as possible to A number in parentheses indicates the year of last reapproval.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Temperature drift during the test should be kept to a minimum and should not exceed Measure the time until the?
Keep the temperature drift to within Originally approved in Precision and Bias Under no conditions should metal cleaning tools be brought into contact with the instrument.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Oils available from other sources, having known kinematic viscosities, may also be used.
Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus.
