See Section 8.13.2.2 chemically undisturbed core samplea soil or rockcore sample in which the sampling device, collection andhandling procedures result in preservation of the chemicalproperties to a de

Nonrepresentative samples may also bechemically undisturbed, but are generally not suitable foranalysi

The sample isonly representative of the subsurface material encountered bythe sampler and is not necessarily representative of theformation being sampled.
42、Sample representativeness in thelatter sense needs to be addressed in the sample design thatdefines the specific location of sampling.3.2.18 rotating core samplera rotating cylindrical samplerwith a coring bit that cuts away soil or rock material fromaround the core.
