Non-destructive Testing (NDT) is a generic term for a wide range of analysis techniques used in science, industry, medicine, forensics and art to evaluate the properties of a material, component, system or structure without causing harm.
Other terms commonly used to describe this technology are Non-Destructive Examination (NDE), Non-Destructive Evaluation (also NDE) and Non-Destructive Inspection (NDI).
As no harm occurs to the items under test it is a very valuable technique used for product evaluation, research and problem solving which can save both time and money. NDT is used widely in all areas of engineering, aerospace, defence, power generation, medicine and art.
Each of the popular methods of NDT is described briefly below and is the subject of individual Lavender NDT Training Programmes at NDT Level 1, 2 and 3.
ACFM – Alternating Current Field Measurement
BRS – Basic Radiation Safety
ET – Eddy Current Testing
HTHA – High Temperature Hydrogen Attack
MT – Magnetic Particle Testing
PT – Liquid Penetrant Testing
RI – Radiographic Interpretation
RPS – Radiation Protection Supervisor
RT – Radiographic Testing
UT – Ultrasonic Testing (including PA – Phased Array and TOFD – Time of Flight Diffraction)
VT – Visual Testing
Around the world are many organisations, institutes and societies who work to provide a better understanding of this science which is vital in its provision of safety in an industrial world.
