It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations asgm to use. Pull the stopper away and simultaneously start the timing device. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
The frequency of this calibration check depends upon the amount of use and the care that the individual cup receives.
Make the viscosity determination at the end of the min period. This standard has been approved for use by agencies of the Department of Defense. Particular care must be exercised in cleaning the ori?
Measure the time until the? Under no conditions should metal cleaning tools be brought into contact with the instrument. A number in parentheses indicates the year of last reapproval.
ASTM D 2. Last previous edition approved in as D — 94 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 r1200 17C and 17F, may be used.
Temperature of Testing 8. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus e1200 be used. Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus.
Allow to stand undisturbed for 10 min while adjusting further to the desired temperature.

Keep the temperature drift asstm within Fill the cup with the prepared specimen. NOTE 1—If the ori? 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. Current edition approved July 1, Determine the time of efflux to the nearest 0. Temperature drift during the test should be kept to a minimum and should not exceed Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
The preferred method is to over? If the ratio of shear stress to shear rate is not constant, the liquid is nonNewtonian.
Care of Cup Precision and Bias If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D should be used.
