Standard Terminology for Nondestructive Examinations

There are, however, appropriate exceptions when the term test and its derivatives may be used to describe the application of a nondestructive test, such as measurements which produce a numeric result for example, when using the leak testing method to perform a leak test on a component, or an ultrasonic measurement of velocity. Compounds do not fall under the strict de? There are, however, appropriate exceptions when the term test and its derivatives may be used to describe the application of a nondestructive test, such as measurements which produce a numeric result for example, when using the leak testing method to perform a leak test on a component, or an ultrasonic measurement of velocity.

A constant intensity signal, irrespective of the circumferential position of a discontinuity, is indicative of electrical centering. NOTE 18—It is not intended for use in judging size nor establishing acceptance limits of discontinuities.

Synonymous terms are standard depth of penetration and skin depth. The beam is coupled to the test surface through the rolling contact area of the tire. The current may be alternating, recti? For small detectors, the detector angular subtenses or projections, a and b, are de?

These relationships are either 1 absolute permeability, which in general is the quotient of a change in magnetic induction divided by the corresponding change in magnetizing force, or 2 relative permeability, which is the ast of the absolute permeability to the magnetic constant g m.

Also known as a penetrameter disparaged. Subsequent annihilation of the positron results in the production of two 0.

NOTE 30—The irradiance varies inversely with the square of the distance; a unique property of point sources. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The MRTD is the minimum temperature difference between a standard periodic test pattern 7: Radiographic exposure is commonly expressed in terms of milliampere-seconds or millicurie-hours for a known source-to-?

By monitoring the AE signal magnitudes of the continuous signal at various points along the object, the source can be determined based on the highest magnitude or by interpolation or extrapolation of multiple readings.
