Allow to stand undisturbed for 10 min while adjusting further to the desired temperature. Box 16, State College, Pa. The frequency of this calibration check depends upon the amount of use and the care that the individual cup receives. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus may be used.
Temperature of Testing d200.
Summary of Test Method 4. Fill the cup with the prepared specimen. A d1020 change in diameter of the ori? Originally approved in Determine the time of efflux to the nearest 0. For particular oils applicable for use with the Ford Cups refer to Table X1.

Calibration Procedure for Ford Cups X1. Last previous edition approved in as D — 94 The preferred method is to over? Under no conditions should metal cleaning tools be brought into contact with the instrument.
Bring this cup and the liquid viscosity standard to a constant temperature as close as possible to 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.
Your comments will receive careful consideration at a meeting of the responsible technical committee, d12200 you may attend. Pull the stopper away and simultaneously start the timing device. 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.
Keep the temperature drift to within 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 cover the temperature range for thermometer 17C and 17F, may be used. Care of Cup Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D should be axtm. Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus.
Temperature drift during the test should be kept to a minimum and should not exceed Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. NOTE 1—If the ori? Make the viscosity determination at the end of the min period. If the ratio of shear stress to shear rate is not constant, the liquid is nonNewtonian. A number in parentheses indicates the year of last reapproval.
Oils available from other sources, having known kinematic viscosities, may also be used. 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.
