This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus. 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.

Oils available from other sources, having known kinematic viscosities, may also be used.
If you feel that your comments ashm not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. If the ratio of shear stress to shear rate is not constant, the liquid is nonNewtonian. The values given in parentheses are for information only. Make the viscosity determination at the end asfm the min period. A number in parentheses indicates the year of last reapproval.

Temperature of Testing 8. Originally approved in Bring this cup and the liquid viscosity standard to a constant temperature as close as possible to Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Temperature drift during the test should be kept to a minimum and should not exceed Keep the temperature drift to within Under no conditions should metal cleaning tools be brought into contact with the instrument. NOTE 2— It is impossible to predict the effect of temperature change on each material with which the apparatus may ast used. The preferred method is to over?
Allow to stand undisturbed for 10 min while adjusting further to the desired temperature.
