ASTM C1565-03

1.1 This test method covers the determination of the pack-set index, which provides an indication of the mechanical force needed to overcome the consolidation of portland cement.

1.2 The pack-set index number provides a numerical value useful for manufacturers who desire to measure and control the effect that vibration-induced consolidation has upon the manufactured cement.

1.3 The values stated in SI units are to be regarded as the standard. Values stated in Inch-Pound units are for informational purposes only and are enclosed in parentheses. Values stated in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the rules of Conversion and rounding given in Standard IEEE/ASTM SI 10, of measurements made in other units.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
