This practice does not apply to hollow-stem augers. Uses of hollow-stem auger drilling methods for geotechnical exploration are addressed in Test Method D Samples recovered from this standard are considered as belonging to Group A or B in accordance with D The samples are disturbed and can generally be used for classification testing D , D , determination of compaction characteristics D , D , or any other standard that requires bulk samples.
For obtaining intact samples use of thin-walled sample tubes D in conjunction with fluid rotary drilling D or hollow-stem augers D may be considered. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 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.
