ASTM Ea Standard Termninology for Nondestructive Examinations_图文_百度文库
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. See also harmonic analysis and phase analysis. Also called a sniffing probe. See also standardization, instrument. With asym exception of accept and reject, which retain the meaning found in most dictionaries, all the words used in the chart are defined in Section A.
The purpose of this standard is to promote a clear understanding and interpretation of the NDT standards in which they are used. AE signal generator—a device which can repeatedly induce a speci?
If it has been interpreted as relevant, the necessary subsequent evaluation will result in the decision to accept or reject the material. Expressed in scale divisions per unit time.
ASTM E1316 – 18a
NOTE 8—This type of location is commonly used in leak location due to the presence of continuous emission. Krypton 85—a tracer gas used to test for leakage when the radioisotope leak test method is used. The light and dark interference lines in the recording medium diffract laser light to produce the reconstruction.
Nondestructive Testing NDTn—the development and application of technical methods to examine materials or components in ways that do not impair future usefulness and serviceability in order to detect, locate, measure and evaluate? Also called the D-log E curve or the H and D curve.
AE signal start—the beginning of an AE signal as recognized by the system processor, usually de? In aastm X-ray tube, the anode carries the target. If it has been interpreted as relevant, the necessary subsequent evaluation will result in the decision to accept or reject the material.
One candela produces 1 lumen of luminous?
The discharge tube is a transparent tube in which the color and form of a cold-cathode discharge without the presence of a magnetic? The Lamb wave can be generated only at particular values of frequency, angle of incidence and material thickness.
False indications are non-relevant. It is determined by the characteristics of the search unit, the ultrasonic test instrumentation, and the test object. If d2F is the? One angstrom unit is equal to 0.
NOTE 21—It can also be used to evaluate liquid penetrant techniques, liquid penetrant systems, or test conditions. NOTE 5— Use atsm the term continuous emission is recommended only for describing the qualitative appearance of emission signals. The outside of the component is examined for the detection of any leaks.

The value is expressed in line pairs per millimetre. Rayleigh wave—an ultrasonic surface wave zstm which the particle motion is elliptical and the effective penetration is approximately one wavelength.
The velocity of the wave is dependent on the mode of propagation and the product of the material thickness and the examination frequency.
Three kinds of aztm in common use are: The standard target is a circle whose size is given by its angular subtense, and both target and background are isothermal blackbodies. This is a variant of the differential amplitude distribution, appropriate for logarithmically windowed data.
Pressure, if required, is then applied to the liquid for the required time and the outside of the component is examined visually for leaks. See also halogen leak detector 2. P—effective pair ast content. Phillips ionization gauge—see ionization vacuum gauge. NOTE 7—Several approaches to computed location are used, including linear location, planar location, three dimensional location, and adaptive location.
