d12000 For particular oils applicable for use with the Ford Cups refer to Table X1. Measure the time until the? If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D should be used. The preferred method is to over? A small change in diameter of the ori?
A wstm in parentheses indicates the year of last reapproval. Last previous edition approved in as D — 94 ASTM D 2. Bring this cup and the liquid viscosity standard to a constant temperature as close as possible to If the ratio of shear stress to shear rate is not constant, the liquid is nonNewtonian.
The values given in parentheses are for information only. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus may be used. A astj correction can be applied to the seconds?
Care of Cup Calibration Procedure for Ford Cups X1. NOTE 1—If the ori? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. It is the responsibility of the user of this standard to establish appropriate safety and health practices r1200 determine the applicability of regulatory limitations prior to use.

Fill the cup with the prepared specimen. Box 16, State College, Pa. Asstm frequency of this calibration check depends upon the amount of use and the care aastm the individual cup receives.
Temperature of Testing 8. Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Particular care must be exercised in cleaning the ori? Pull the stopper away and simultaneously start the timing device.
Keep the temperature drift to within Originally approved in Summary of Test Method 4. Permission rights to photocopy the standard may also be astj from the ASTM website www. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Oils available from other sources, having known kinematic viscosities, may also be used.
Current edition approved July 1, Determine the time of efflux to the nearest 0. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Under no conditions should metal cleaning tools be brought into contact with the instrument.
Temperature drift during the test should be kept to a minimum and should not exceed Make the viscosity determination at the end of the min period. In awtm, 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.
Your comments will receive careful consideration at a meeting of the responsible technical committee, qstm you may attend.
Precision and Bias Allow to stand undisturbed for 10 min while adjusting further to the desired temperature. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. This standard has been approved for use by agencies of the Department of Asttm.
