The LED-Technology is strongly substituting the conventional bulb based UV source (Mercury-Vapor, Xenon and Metal-Halide) in the fluorescent NDT methods in all industries.

The NDT industry is getting more and more aware that the quality and characteristics of the LED UV lamps is essential to ensure at least the quality and performance of the inspection process as when using a 100W Mercury vapor lamp. There are also made big efforts by the Aerospace industry to explain the need and the technical background to the users in parts manufacturing.

A new and more restrictive Aerospace manufacturer standard has been released in the Aerospace industry that ensures adequate quality of the LED UV sources for mag and pen. It also requires that the user takes care about the proper function during the usage of LED UV sources on a regular basis.

The presentation will give an overview of the requirements and characteristics that came up, will explain the technical need of those to ensure a secure and reliable inspection process and will explain the new parametrization that has been established to describe easy and understandable the characteristics of LED UV sources for easy selection and good practical use of LED UV sources.
