ABSTRACT
The purpose of this chapter is to aid the reader in ensuring that data obtained from a CPT/CPTU is of a known quality and presented in a clear and systematic way. The chapter is divided into three sections covering (a) factors that might affect the measurements and how to avoid or correct for them; (b) the presentation of data to ensure that it is of most use and (c) a summary guide to information required to enable checking of the data quality.
