With the exception of accept and reject, which retain the meaning found in most dictionaries, all the words used in the chart are de? Pressure, if required, is then applied to the liquid for the asym time and the outside of the component is examined visually for leaks. In many outdoor applications, visibility is de? C-scan—an ultrasonic data presentation which provides a plan view of the test object, and discontinuities therein.

Your comments will receive careful consideration at r1316 meeting of the responsible technical committee, which you may attend. Also known as the Fresnel zone. B-scan presentation—a means of ultrasonic data presentation which displays a cross section of the specimen indicating the approximate length as detected per scan of re? Coils of this type are also referred to as annular, circumferential, or feed-through coils.

NOTE 12—The magnetic constant gm is a scalar quantity differing in value and uniquely determined by each electromagnetic system of units. NOTE 25—When the output indications can be related to the size of recognized targets, such as?

MV mega or million volt —a unit of electrical potential difference equal to one million volts, used to describe the accelerating potential of an X-ray tube. Yokes may be permanent magnets or either alternating-current or direct-current electromagnets. NOTE 19—In the case where the recording medium is placed directly in contact with the object being examined, the distance is equal to the thickness of the object. Additional radiologic testing terms are found in Section H.

NOTE 16—For the incremental permeabilities? Compounds do not fall under the strict de? False indications are non-relevant. 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.

One curie is equivalent to 3. See also rate of rise. Krypton 85—a tracer gas used to test for leakage when e13116 radioisotope leak test method is used.

A form of dynamic leak test in which the entire enclosure or a large portion of its external surface is exposed to the tracer gas while the interior is connected to a leak detector with the objective of determining the existence of leakage. NOTE 22—In practice, meaningful experimental values can be obtained in an isotropic neutron? If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

These nondestructive testing NDT methods include: One angstrom unit is equal to 0. For eddycurrent testing described herein, the frequency is normally 1 to kHz, inclusive. Pa and less as to subject all parts of the test object to examination at one time.

E116 value and dimension of absolute permeability depends on the system of units employed.

IFOV may also be expressed as a solid angle in units of sr. The common types are listed below: Phillips ionization gauge—see ionization vacuum gauge. The principal types are as follows: See also standardization, instrument.

The depth of penetration is an exponential function of the frequency of the signal and the conductivity and permeability of the material. Radiologic Testing RT is often used to examine material to detect internal discontinuities. Nondestructive Examination—see Asym Testing. Synonymous terms are standard depth of penetration and skin depth.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, asmt entirely their own responsibility. Bayard-Alpert ionization gauge—see ionization vacuum gauge.

ASTM E – 18a – Standard Terminology for Nondestructive Examinations

The current may be alternating, recti? ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. NOTE 4—Use of the term burst emission is recommended only for describing the qualitative appearance of emission signals.

It is, therefore, not proper to translate a numerical setting on one instrument to that of another type.

AE signal start—the beginning of an AE signal as recognized by the system processor, usually de? This effect is also termed the end effect. The mass spectrometer may be used as a vacuum gauge that relates an output which is proportioned to the partial pressure of a speci? Nondestructive Inspection—see Nondestructive Testing. SE probe—see dual search unit twin probe.

In this case, any object information contained in the reference beam is cancelled in the object beam by the interference between the object beam and the reference beam. NOTE 14—For any ferromagnetic material, permeability is a function of the degree of magnetization. A superscript epsilon e indicates an editorial r1316 since the last revision or reapproval. Last previous edition approved in as E — SI unit of luminous? The data cannot be altered.
