6. Using DIN 2303 in Practice – Step by Step

  1. Perform penetrant testing per ISO 3452-1.
  2. Develop and evaluate indications under appropriate UV/white light.
  3. Measure all relevant indications (length, width, spacing).
  4. Identify component zone (if multiple acceptance levels exist on drawing).
  5. Compare against the required acceptance class table from DIN 2303.
  6. Decide:
    • Accept
    • Repair (if allowed) and re-test
    • Reject
