For particular oils applicable for use with the Ford Cups refer to Table X1. Fill the cup with x1200 prepared specimen. Box 16, State College, Pa.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus may be used.
Last previous edition approved in as D — 94 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.
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 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 Oils available from other sources, having known kinematic viscosities, may also be used.
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.
Originally approved in Summary of Test Method 4. Particular care must be exercised in cleaning the ori?

Determine the time of efflux to the nearest 0. If the material is non-Newtonian, that is, shear-thinning or thixotropic, Test Method D should be used. The frequency of this calibration check depends upon the amount of use and the care that the individual cup receives.
Allow to stand undisturbed for 10 min while adjusting further to the desired temperature. A number in parentheses indicates the year of last reapproval.

Pull the stopper away and simultaneously start the timing device. 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.
