What must be checked after corrosion has been completely removed?

• A. The remaining material must be measured up to complete a proper assessment
• B. The surface color
• C. The surface roughness
• D. The amount of cleaning solvent remaining

Answer: (A)

After corrosion is removed, you must measure the remaining material thickness to complete the assessment. This check shows whether enough metal is left to meet thickness specifications and to determine if the part can continue in service or needs repair or replacement. Visual cues like surface color or roughness don’t reliably indicate how much material remains, and residual cleaning solvent is a cleaning concern rather than a measure of structural integrity. Quantifying the remaining material is the essential step to ensure the part is safe and compliant.
