: Because visual inspection only catches surface-level issues, it is often paired with other tests like SP-53 (Magnetic Particle) SP-54 (Radiographic) to find hidden internal cracks. Why It Matters In industries like Power Generation
The standard divides surface irregularities into 12 distinct categories. For each category, the standard defines what constitutes an acceptable surface condition and what qualifies as a defect requiring rejection or repair. The 12 Categories of Surface Irregularities MSS SP-55 evaluates the following casting anomalies:
