This standard practice covers the NACE external corrosion confirmatory direct assessment (ECCDA) process for buried onshore ferrous piping systems. ECCDA is a continuous improvement process that was developed to improve pipeline safety, and it has the advantage and benefit of locating areas where corrosion is likely to occur in the future, not just areas where corrosion has already occurred. ECCDA can be used to validate previous assessment conclusions or determine if reassessment intervals are still appropriate, and the ECCDA process may detect additional pipeline integrity threats such as mechanical damage, stress corrosion cracking, and microbiologically influenced corrosion. This standard covers the four components of ECCDA: Preassessment, Indirect Inspection, Direct Examination, and Postassessment.
