Particular care e1200 be exercised in cleaning the ori? Pull the stopper away and simultaneously start the timing device. Determine the time of efflux to the nearest 0. Bring this asmt and the liquid viscosity standard to a constant temperature as close as possible to This standard is subject to revision s1200 any time by the responsible technical committee and must be reviewed every? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Summary d1020 Test Method 4. If the ratio of shear stress to shear rate is not constant, the liquid is nonNewtonian. Under no conditions should metal cleaning tools be brought into contact with the instrument. The frequency of this calibration check depends upon the amount of use and the care that the individual cup receives. This standard has been approved for use by agencies of the Department of Defense. For particular oils applicable for use with the Ford Cups refer to Table X1.
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. A asstm in parentheses indicates the year of last reapproval. Fill the cup with the prepared specimen. Precision and Bias NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus may be used.
