Which statement describes Stage 3 and Stage 4 as metal conditions?

• A. Metal Sound
• B. Metal Deteriorated
• C. Metal Unsound
• D. Metal Prone to Cracking

Answer: (C)

Stage 3 and Stage 4 indicate that the metal is unsound. In this assessment framework, sound means the material is healthy with no significant damage and is safe to continue in service. Deteriorated suggests some loss of material or damage, but not to the point of compromising overall integrity. Prone to cracking points to a risk or tendency for cracking, rather than a current, comprehensive evaluation of the metal’s condition. Unsound means the metal’s structural integrity is meaningfully compromised, requiring evaluation and likely repair or replacement to prevent failure. So Stage 3 and Stage 4 are described as unsound because they reflect a level of degradation where continued service is not considered safe without corrective action.
