Standard Test Method for Moisture Content Penetration Resistance Relationships of Fine-Grained Soils

SCOPE
1.1 This test method is for establishing the moisture-penetration resistance relationships of fine-grained soils as determined by the soil penetrometer.
1.2 The values stated in inch-pound units are to be regarded as the standard.  
1.3 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.
