PURPOSE:To easily permit measurement of consisting even with a small quantity of viscous substances by a method wherein the calibration curve is obtained by measuring reference samples with known consistency, a sample is put between two sheets of plates at least one of which is transparent, and then a given load is applied thereon for a predetermined time. CONSTITUTION:A small quantity of sample grease 3 to be measured is put on the center of a lower glass plate 2 using a microspatula or the like. An upper glass plate 1 is placed on the sample and then a weight 4 of ca. 1kg is put thereon. After holding them in this state motionless for a predetermined time, the weight 4 is removed and the diameter of a spread 6 of the sample grease on the glass plate 1 is immediately measured at two or more points. The average value of thus measured results is calculated. In this way, using several kinds of greases having different consistency, the reference curve is obtained based on the relationship between the average diameter of the spread and the consistency. Next, similar operation is carried out on a sample with not yet known consistency to measure the average diameter of spread of the sample. The consistency of the sample can be attained by comparing thus measured result with the calibration curve. |
