1 Scope
This standard defines the terms and definitions used in eddy current testing.
This standard is applicable to eddy current testing, nondestructive testing and other relevant areas.
2 General Terms Specifically Associated with the Eddy Current Testing
2.1
eddy currents
Electric current induced into a conductive material by a varying magnetic field
2.2
pulsed eddy currents
Eddy currents generated by a pulsed electromagnetic field
2.3
eddy current distribution
Vector field of eddy current density
2.4
eddy current testing
Non destructive test method using the electromagnetic effects of induced currents to evaluate the product to be tested
2.5
electromagnetic testing
A nondestructive testing method makes use of electromagnetic fields of the frequency below the visible light. Eddy current testing, microwave testing are belong to this kind of testing method
2.6
integrated electromagnetic testing
A test piece is simultaneously tested by two or more kinds of electromagnetic testing techniques (for example, eddy current testing, magnetic flux leakage testing and magnetic memory testing)
?
2.7
electromagnetic coupling
Electromagnetic interaction between two or more circuits. In eddy current examination the product to be tested is a circuit
2.8
coupling factor
Ratio of the excitation flux through the product to be tested to the total excitation flux. It measures the electromagnetic coupling between the probe and the product to be tested
2.9
resultant magnetic field
Magnetic field resulting from the vectorial addition of the primary and the secondary fields
