PH Tool Reference Standards


NDT reference standards are a primary element of all NDT procedures, detection capability and reliability. “All cracks are not created equal” and responses vary with crack size and characteristics. In like manner, “All EDM (electrodischarge machined) notches are not created equal and the integrity of the reference standard is an essential element to the integrity of an inspection result. Differences in reference standards (and resultant NDE responses) become even more important when an inspection is performed at more than one location. This is NDT Reference Standards 101 and is your chance to learn, ask questions and enjoy.

NDT Reference Standards:

  • What are they?
  • How are they made?
  • Why do I need them?
  • And, why are they so expensive?
