Adhesion failure and/or detachment of ceramic tiling are common building defects. Bonding rupture of this type of coating presents a serious risk to people’s safety, in particular if it occurs on external façades. It may be avoided by earlier non-destructive inspections. This paper presents the results of an active thermography investigation in which adhesive bonding defects of ceramic coatings...

In application of the act of 25 July 1980 that provided for nuclear materials to be nationally controlled in France, IRSN carries out inspections covering the physical protection of nuclear materials, physical follow-up, and accountancy within French facilities. Some inspections give rise to physical verifications of nuclear materials held by operators, resorting to non-destructive measurement....

An arrival time of an elastic wave is the important parameter to visualize locations failures and/or velocity distributions in field non-destructive testing (NDT). The detection conducted generally using automatic picking algorithms a measured time-history waveform. According algorithms, it expected that detected from low S/N signals has accuracy if are measurements. Thus, order accurately dete...

Describes the application of an ultrasonic sensing system for the non-destructive inspection of welds as an alternative to X-rays. Replacing radiography with ultrasound not only allows faster, more economical inspections but also eliminates the health and safety risks associated with radiography. In practical terms that means there is no need to evacuate the site for inspection purposes ± const...

Inspection qualification is the term currently used to describe the process of independent assessment of a specific non-destructive test to ensure that it is capable of meeting its objectives. Such activities carried out on the Sizewell B reactor inspections were referred to as validation. In the USA, the term performance demonstration is used, though this is increasingly being reserved for the...

A procedure for selecting an optimal NDI (non-destructive inspection) technique and associated schedule for fracture-critical member inspections on a specific steel bridge is presented. Information related to the probability of detection (POD) function (a measure of inspection quality) of alternative NDI techniques is utilized. Calculations based on use of the POD function together with Monte C...

The operational safety and reliability of an airplane must be integral part its design. use suitable materials that pass material certification tests is very important for a new aircraft next testing specific samples, sub-components, components such as the aileron. paper deals with non-destructive evaluation composite primary structural fatigue in accordance damage tolerance philosophy consider...
