Which statement describes Stage 1 and Stage 2 as metal conditions?

• A. Metal Unsound
• B. Metal Sound
• C. Metal Deteriorated
• D. Metal Corroded

Answer: (B)

Stage 1 and Stage 2 indicate metal that is still sound. In corrosion assessments, “sound” means the metal shows no significant loss of thickness and no signs of structural compromise; the surface may have minor wear, but the substrate remains intact and capable of carrying loads. If a metal were unsound, deteriorated, or corroded, you’d expect defects, material loss, pits, or corrosion products that reflect compromised integrity. So describing Stage 1 and Stage 2 as Metal Sound best fits what those stages denote.
