Standard Test Method for Mechanical Cone Penetration Tests of Soil (Withdrawn 2014)
1.1 This test method covers the determination of end bearing and side friction, the components of penetration resistance that are developed during the steady slow penetration of a pointed rod into soil. This test method is sometimes referred to as the Dutch Cone Test or Cone Penetration Test and is often abbreviated as CPT.
1.2 This test method includes the use of mechanical cone and friction-cone penetrometers. It does not include the use of electric and electronic cones or data interpretation.
1.2.1 The use of electric and electronic cones is covered in Test Method D 5778.
1.3 Mechanical penetrometers of the type described in this test method operate incrementally, using a telescoping penetrometer tip, resulting in no movement of the push rods during the measurement of the resistance components. Design constraints for mechanical penetrometers preclude a complete separation of the end-bearing and side-friction components.
1.4 UnitsThe values stated in inch-pound units are to be regarded as standard, except as noted below. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
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.
