Ultrasonic Inspection
Nondestructive inspection is one of the best ways to test the product meant for critical applications such as vessels under pressure, aerospace and other. For testing of aluminium alloy products ultrasonic inspection is widely used.
Chapter I. USI discontinuity classes definitions
Following USI classes are defined by registered defect sizes:
| Class | Single discontinuity response equal to artificial reflector diameter |

| AAA | 0.015'' (0.4 mm) |
| AA | 0.047'' (1.19 mm) |
| A | 0.078'' (1.98 mm) |
| B | 0.125'' (3.18 mm) |
| C | 0.125'' (3.18 mm) |
