FAQ-132: Reassessment Schedule when Defects found during Confirmatory DA

Go To FAQ#:

Question: How do I determine a new reassessment schedule if I identify defects requiring remediation using ICDA during a CDA assessment?

Answer: The rule specifies that sections 6.2 and 6.3 of NACE RP-0502-2002 must be used to schedule the next reassessment if CDA identifies any defects requiring remediation prior to the next scheduled assessment
(192.931(d)). Even though the NACE standard, as a whole, is not applicable to ICDA, these sections still must be used in scheduling new assessments when internal corrosion defects are revealed during CDA.
