It is one of the most common and most powerful means of non-destructive testing.

• Liquid Penetrant Testing

• Visual Inspection

• Ultrasonic Testing

• Eddy Current Inspection

It is defined as an orderly movement of electrons from one part of a circuit to another.

• Resistance

• Voltage

• Current

• Electricity

It is a magnet that retains its magnetism after removal of the magnetizing force.

• Temporary Magnet

• Electromagnet

• Permanent Magnet

It is a discontinuity that lies deep within the object, however, may not disturb the lines of force sufficiently to cause them to emerge from the surface.

• Internal Discontinuity

• Surface Discontinuity

It refers to the continuous magnetizing of the parts simultaneously applying the inspection medium while the current is flowing.

• Electromagnetic Field

• Remanent Field

• Continuous Field

It uses high frequency sound waves (typically in the range between 0.5 and 15 MHz) to conduct examinations and make measurements.

• Ultrasonic Testing

• Radiographic Testing

• Visual Inspection

• Magnetic Particle Testing

The most basic eddy current testing instruments includes:

• Coil of wire

• Voltmeter

• Alternating Current Source

• All of the above

It is a reference document for Non-Destructive Testing-Qualification and Certification of Personnel.

• EN 473

• ISO 9712

• EN 4179 Aerospace Series

• ISO 9722

This is a method which can be employed for the detection of open-to-surface discontinuities in any industrial product which is made from a non-porous material.

A period of time is allowed for it to enter discontinuity open to that surface through ______.
