ASTM D1403 - Quarter & Half Cone Penetration of Grease
We perform grease quality testing by ASTM D1403 to measure the consistency of lubricating grease using a smaller cone penetration apparatus. ASTM D1403 is used when the sample is too small to use ASTM D217. This test uses a ¼-scale cone or a 1/2-scale cone to measure the penetration of worked and unworked grease samples. The reduced-scale penetration values are converted to full-scale penetration values. These results can be used to establish the NLGI consistency of the grease or to evaluate the effect of storage conditions on grease consistency.

ASTM D1403 corresponds to IP 310.
