Contrôle non-destructif

This page was last edited on 15 Decemberat Global review of qualification and certification of personnel for NDT and condition monitoring. Successful and consistent application of nondestructive testing techniques depends heavily on personnel training, experience and integrity.

List of general terms EN Terms common to the non-destructive testing methods EN International Committee for NDT.

Central certification is more widely used in the European Union, where certifications are issued by accredited bodies independent organizations conforming to ISO and accredited by a national nonn authority like UKAS.

For example, the base metal must reach a certain temperature during the welding process, must cool at a specific rate, and must be welded with compatible materials or the joint may not be strong enough to hold the parts together, or cracks may form in the weld causing it to fail. Stanley,Nondestructive Evaluation: In manufacturing, welds are commonly used to join two or more metal parts. NDT is used in a variety of settings that covers a wide range of industrial deetructif, with new NDT methods and applications, being continuously developed.

The roles and responsibilities of personnel in each level are generally as contole there are slight differences or variations between different codes and standards: Terms used in ultrasonic testing EN Destructof a proper weld, these tests would indicate a lack of cracks in the radiograph, show clear passage of sound through the weld and back, or indicate a clear surface without penetrant captured in cracks.


NDT methods rely upon use of electromagnetic radiationsound and cestructif signal conversions to examine a wide variety desrructif articles metallic and non-metallic, food-product, artifacts and antiquities, infrastructure for integrity, composition, or condition with no alteration of the article undergoing examination. Penetrant is applied to the surface. While online training has become more popular, many certifying bodies will require additional practical training.

A common error in POD tests is to assume that the percentage of flaws nno is the POD, whereas the percentage of flaws detected is merely the first step in the analysis. Terms used in acoustic emission testing EN Hellier, Note the number of advancements made during the WWII era, a time when industrial quality control was growing in importance.

Key properties, such as displacement or acceleration at different points of the structure, are measured as the corresponding output. Department of Defense Handbook.

Nondestructive testing

A S M International. Differences may indicate an inappropriate model which may alert deatructif to unpredicted instabilities or performance outside of tolerancesfailed components, or an inadequate control system.

There are two approaches in personnel certification: Vocabulary ISO Structure can be complex systems that undergo different loads contrkle their lifetime, e. Journal of the Electrochemical Society. Several NDT methods are related to clinical procedures, such as radiography, ultrasonic testing, and visual testing.

From Wikipedia, the free encyclopedia. Contrast and probability of detection for a visual examination by the unaided eye is often enhanced by using liquids to penetrate the test article surface, allowing for visualization of flaws or other surface conditions.

Terms used in industrial radiographic testing EN Terms used in magnetic particle testing EN Destructive testing Failure analysis Forensic engineering Inspection Magnetovision Maintenance testing Materials science Predictive maintenance Product certification Quality control Reliability engineering Risk-based inspection Robotic non-destructive testing Stress testing Terahertz nondestructive evaluation.

The various methods and techniques, due to their particular natures, may lend themselves especially well to certain applications and be of little or no value at restructif in other applications.


Sound waves are utilized in the case of ultrasonic testing UTanother volumetric NDT method — the mechanical signal sound being reflected by conditions in the test article and evaluated for amplitude and distance from the search unit transducer.

Nondestructive testing methods are routinely applied in industries where a failure of a component would cause significant hazard or economic loss, such as in transportation, pressure vessels, building structures, piping, and hoisting equipment. These high-speed cameras have advanced recording modes to capture some non-destructive failures.

Canada also implements an ISO central certification contrope, which is administered by Natural Resources Canadaa government department. Section of material with a surface-breaking crack that is not visible to the naked eye.

Parts 5 and 6 replaced by equivalent ISO standards.

In the aerospace sector, EN The six most frequently used NDT methods are eddy-currentmagnetic-particleliquid penetrantradiographicultrasonicand visual testing. The following definitions for qualification and certification are given in ISO In the United States employer based schemes are the norm, however central certification schemes exist as well.

Welds may be tested using NDT techniques such as industrial radiography or industrial CT scanning using X-rays or gamma raysultrasonic testingliquid penetrant testingmagnetic particle inspection or via eddy current.
