The intent of this document is to describe the major aspects of the sampling process, from specific sample identification, determination of analytical requirements, through sample point design, to sample collection. Consideration of these aspects is necessary for the development of robust and safe sampling programs, protocols, and procedures to facilitate indirect corrosion monitoring.

This document is to assist end users in the development of sampling programs. The guidance is structured to provide an awareness of the major aspects of program design, which if not addressed, may have a significant negative impact on the overall performance of these programs. While this document has been primarily developed with a focus on sampling for indirect internal corrosion monitoring; the basic concepts have a broader applicability and may be of benefit to those developing sampling programs in other areas or for other requirements.
