These numerical settings differ among instruments of different types. Felicity ratio—the ratio of the stress at which the Felicity effect occurs to the previously applied maximum stress. For small detectors, the detector angular subtenses or projections, a and b, are de?

Acoustic Emission The terms de? NOTE wstm general, passive thermography refers to examination of an object or system during its normal operational mode, without the application of any additional energy source for the express purpose of generating a thermal gradient in the object or system; active thermography refers to the examination of an object upon intentional application of an external energy source.

In some tests, the reference beam may be re? The voltage threshold may be user adjustable,? The time displacement data can be used with conventional hit based location techniques to arrive at a solution for the source site.

The term is used to describe single crystal piezoelectrics as well as polycrystalline piezoelectrics, such as ferroceramics. Nondestructive Examination—see Nondestructive Testing. Synonymous terms are standard atm of penetration and skin depth. NOTE 13—Relative permeability is a pure number which is the same in all unit systems.

The light and dark interference lines in the recording medium diffract laser light to produce the reconstruction.

V at the preampli? If it f1316 been interpreted as relevant, the necessary subsequent evaluation will result in the decision to accept or reject the material.

ASTM E – 18a Standard Terminology for Nondestructive Examinations

In many outdoor applications, visibility is de? Measured in the SI system by lux.

NOTE 30—The irradiance varies inversely with the square of the distance; a unique property of point sources. 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.

With the exception of accept and reject, which retain the meaning found in most dictionaries, all the words used in the chart are de? This effect is also termed the end effect. The data cannot be altered. In laser systems, it results in the granular effect which can be seen in a scattered beam.

Various types of ionization gauges are distinguished in accordance with the method of producing the ionization. Also called clean-up time.

Bayard-Alpert ionization gauge—see ionization vacuum gauge. The process is also termed wash. See also calibration, instrument. The pattern is used with an imaging device to measure spatial resolution.

The purpose of this standard is to promote a clear understanding and interpretation of the NDT standards in which they are used. D i, a numerical value is meaningless unless both the corresponding values of mean excitation level B or H and the excursion range DB or DH are speci? See also absolute coil. For eddycurrent testing described herein, the frequency is normally 1 to kHz, inclusive. V at the sensor, before ampli? The coherence length is related to the width of the spectral line emitted from the laser: The velocity of the wave is dependent on the mode of propagation and asfm product of the material thickness and the examination frequency.

The coated surface ast placed next to the? In discussing the action of a vapor jet, the term forepressure may be used to designate the total pressure of the gas against which the jet impinges. The Lamb wave can be generated only at particular values of frequency, angle of incidence and material thickness. Neutrons are slowed down when they collide with atoms of light elements such as hydrogen, deuterium, beryllium, and carbon.

The device generally consists of a nameplate, asrm, case, backing, piezoelectric element, wearface, or lens, or wedge. The value in decibels e116 is 8. AE signal generator—a device which can repeatedly induce a speci?

It consists of two protons and two neutrons, and is identical to the nucleus of a helium atom. The beam is coupled to the test surface through the rolling contact area of the tire. In outdoor applications it usually is de?

The volume and temperature of the system are held constant during the rate of rise measurement. Also called the D-log E curve or the H e1361 D curve. The variations in thickness or index refract coherent light to produce the reconstruction. See also halogen leak detector 2.
