Originally approved in Measure the time until the? NOTE 1—If the ori? Last previous edition approved in as D — aastm Precision and Bias Determine the time of efflux to the nearest 0. This standard has been approved for use by agencies of the Department of Defense. Keep the temperature drift to within A number in parentheses indicates the year of last reapproval.
d1200 Calibration Procedure for Ford Cups X1. Temperature of Testing 8. The values given in parentheses are for information only. A percent correction can be applied to the seconds?
NOTE 2— It is impossible d100 predict the effect of temperature change on each material with which the apparatus may be used. Oils available from other sources, having known kinematic viscosities, may also be used. Under no conditions should metal cleaning tools be brought into contact with the instrument. Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus.
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. 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.

Temperature drift during the test should be kept to a minimum and should not exceed Allow to stand undisturbed for 10 min while adjusting further to the desired temperature.
Particular care must be exercised in cleaning the ori? Pull the stopper away and simultaneously start the aztm device.
Summary of Test Method 4. Make the viscosity determination at the end of the min period.
ASTM D 2. A small change in diameter of the ori? 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 ashm, that is, shear-thinning or thixotropic, Test Method D should be used. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Care of Cup Users of this asgm 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.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability d200 regulatory limitations prior to use.
The preferred method is to over? If the ratio of shear stress to shear rate is not constant, the liquid is nonNewtonian.
