What are the sensitivity levels?

Explanation:
In liquid penetrant testing, sensitivity levels describe how responsive the method is to reveal surface-breaking flaws, ranging from very low to very high. The standard scale used includes five steps: 1/2 Ultra Low, 1, 2 Normal, 3, and 4 Ultra High. This provides a consistent ladder to calibrate and compare inspection capability, and to set process controls and training against reference indications. The choice that lists these five levels exactly reflects that established scale. Other options either shorten the range, use different terms like Low/Medium/High, or don’t form a valid, recognized scale for LPI.
