Published on

Remote visual inspection in visible light may not always identify all defects in manufactured items or determine the true state of existing infrastructure. Dye penetrant inspection using videoscopes with UV light enables in-depth inspection of component interiors.

This webinar is focused on automotive manufacturing applications where inspection rate and production quality requirements are high. We’ll discuss how new IPLEX G series industrial videoscopes with an interchangeable UV light source can help you see the invisible.

What you’ll learn:

UV inspection overview
Application examples and industry standards
How IPLEX G series industrial videoscopes add value to your inspection

  10. 10. 10 One of Many FPI Industry Standards ASTM E1417/E1417M-16 STANDARD PRACTICE FOR LIQUID PENETRANT TESTING § The revised ASTM Standard states that the equipment must be capable of irradiance of 1000 µW per cm² at no specified distance. § The typically small diameter of videoscopes significantly limits the amount of UV light output, so shorter distances are required to produce the same irradiance.
