scope:

Section one of this International Standard specifies four procedures for determination of the consistency of lubricating greases by measurement of the penetration of a standard cone. These procedures cover the measurement of unworked, worked, prolonged worked, and block penetrations. Penetrations up to 620 units may be measured. Section two of this International Standard specifies methods for the determination of the consistency of lubricating greases, when only small samples are available, by the use of cones a half or quarter scale of that used in Section one. The methods are applicable to greases having penetrations of 175 to 385 units with the standard cone and are intended for use only if the size of the test sample prevents the use of Section one. Section three of this International Standard specifies a method for determination of the consistency of petrolatums by measurement of the penetration of a standard cone, having penetrations up to 300 units. This method may also be used to estimate the consistency of slack waxes. Section four of this International Standard describes the calculation of results, precision data and the test report.
