Receiving shop-primed steel, which field audit commonly checks primer build before field assembly?
Choices
- (A) Solvent sniff test only
- (B) DFT gauge readings on edges and connection-adjacent spots per ITP sampling
- (C) Gloss appearance alone
- (D) Defer all gauges to fabrication only
Correct answer: (B)
DFT gauge readings on edges and connection-adjacent spots per ITP sampling
Explanation
Edges are thin spots vulnerable to rust bloom.
