Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Measure the time until the? ASTM D 2. Fill the cup with the prepared specimen. Permission rights to photocopy the standard may d12200 be secured from the ASTM website www. For particular oils applicable for use with the Ford Cups refer to Table X1. Precision and Bias Last previous edition approved in as D — 94 Determine the time of efflux to the nearest 0. Temperature of Testing 8.
NOTE 2— It is impossible to 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.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Make the viscosity determination at the end of the min period. Summary of Test Method 4. Care of Cup The values given in parentheses are for information only. Temperature drift during the test should be kept to a minimum and should not exceed This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Wstm, at the address shown below. The frequency of this calibration check depends upon the amount of use and the care that the individual cup receives.
Determinations should be made at a temperature above the dew point of the atmosphere surrounding the apparatus. The aetm method is to over?
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 Box 16, State College, Pa. Current edition approved July 1, Your comments will receive careful consideration at e1200 meeting of the responsible technical committee, which you may attend.
Particular care must be exercised in cleaning the ori? Bring this cup and the liquid viscosity standard to a constant temperature aatm close as possible to 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.
A small change in diameter of the ori? Under no conditions should metal cleaning tools be brought into contact with the instrument.
Pull the stopper away and simultaneously start the timing device. Keep the temperature drift to within
