Non-Destructive Testing (NDT)

• Introduction

• Standard NDT methods

• NDT and PED

• EN standards

• EN 473 – Personnel Qualification and Certification

• EFNDT

GENERALLY

Detection and quantitive description of deviations without distroying the usability of inspected specimen.

Tasks of NDT

IN PARTICULAR

• Detection of rough structure defects at the surface of the test specimen and inner defects.

• Sizing of these defects.

• Detection of microstructure characteristics or defects.

APPLICATION of NDT

• During the manufacturing process within general quality assurance processes.

• During in-service inspection, e.g., for lifetime prediction.
