This enables the individual leaks to be located. Bayard-Alpert ionization gauge—see ionization vacuum gauge. This would include paramagnetic materials and diamagnetic materials.

The depth of penetration is an exponential function of the frequency of the signal and the conductivity and permeability of the material. Nondestructive Evaluation—see Nondestructive Testing.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Radiographic exposure is commonly expressed in terms of milliampere-seconds or millicurie-hours for a known source-to-? See also differential coils. Compounds do not fall under the strict de? This is a variant of the differential amplitude distribution, appropriate for logarithmically windowed data.

Various types are distinguished by the method of separating the ions. Pirani gauge—see thermal conductivity vacuum gauge. In laser systems, it results in the granular effect which can be seen in a scattered beam. In some tests, the reference beam may be re?

A superscript epsilon e indicates an editorial change since the last revision or reapproval. The common types are as follows: In infrared thermography, an apparatus that measures the average apparent temperature of the surface subtended by its?

See also absolute coil. The response of mixture of a tracer and nonhalogen gases will be the response factor of the tracer divided by the fraction of tracer gas in the test gas. For small detectors, the detector angular subtenses or projections, a and b, are de? NOTE 28—For a given target size, the MDTD is the minimum temperature difference between the target and its background at which the observer can detect the adtm.

Coils of this type are also referred to as annular, circumferential, or feed-through coils.

Sometimes called the back pressure, backing pressure, outlet pressure, exhaust pressure, or discharge pressure. Link to Active This link will always route to the current Active version of the adtm. Normally expressed in decibel per unit length. Nondestructive Inspection—see Nondestructive Testing.

Expressed in scale divisions per unit time. See also calibration, instrument. The purpose of this standard is to promote a clear understanding and interpretation of the NDT standards in which they are used. P is the percent background exposure caused by pair production in 2 mm of lead. NOTE 21—It can also be used to evaluate liquid penetrant techniques, liquid penetrant systems, or test conditions.

NOTE 32—In 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.

Each property of a given material may have its own optimum frequency. Krypton 85—a tracer gas used to test for leakage when the radioisotope leak test method is used.

Last previous edition ast in as E — The light and dark interference lines in the recording medium diffract laser light to produce the reconstruction. MeV mega or million electron volts —a unit of energy equal to one million electron volts, used to express the energy of X—rays, gamma rays, electrons, and neutrons. The Bayard-Alpert ionization gauge employs a tube with an electrode structure designed to minimize X-ray-induced electron emission from the ion collector. Since the ejected electron has short range in most materials, it is not considered part of the scattered radiation.

ID coil—a coil or coil assembly used for ee1316 testing by insertion into the test piece as in the case of an inside probe for tubing.
