Compounds do not fall under the strict de? NOTE 32—In general, passive thermography refers to examination of an object or system during its normal operational mode, without the r1316 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. Acoustic Emission The terms de? NOTE 24—Dynamic range may be stated as the numerical value of the ratio; however, this is usually expressed in decibels.

With the exception of accept and reject, which retain asttm meaning found in most dictionaries, all the words used in the chart are defined in Section A. Data may be recorded with a system examination threshold lower than the evaluation threshold.

Measurement of travel times for the forward re? The path is usually shaped like the letter V. Pressure, if required, is then applied to the liquid for the required time and the outside of the component is examined visually for leaks.

Bayard-Alpert ionization gauge—see ionization vacuum gauge. The purpose of this standard is to promote a clear understanding and interpretation of the NDT standards in which they are used. NOTE 9—Several approaches to zone location are used, including independent channel zone location,?


For eddycurrent testing described herein, the frequency is normally 1 to kHz, inclusive. A-scan—a e136 of data presentation utilizing a horizontal base line that indicates distance, or time, and a vertical de? The sources would normally be within the array. The MRTD is the minimum temperature difference between a standard periodic test pattern 7: Pa and less as to subject all parts of the test object to examination at one time. At the end of the test period the chamber is opened to a leak detector which is sensitive to the gas.

NOTE 22—In practice, meaningful experimental values can be obtained in an isotropic neutron? Radiologic Testing RT is often used to examine material to detect internal discontinuities. Thus, the ast, leak rate of a detected leak will be the indication of the detector multiplied by the response factor. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

NOTE 16—For the incremental permeabilities? 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.

ASTM E1316 – 18a

In infrared thermography, an apparatus that measures the average apparent temperature of the surface subtended by its? SE probe—see dual search unit twin probe. It should be noted that such noise signals may be generated by inhomogeneities in the inspected part that are not detrimental to the end use of the part. For ideal gases the concentration ratio has the same value as the volume fraction or the partial pressure of the constituent. Leakage rates are expressed in various units such as pascal cubic metres per second or pascal litres per second see Table 3.

For small detectors, the detector angular subtenses or projections, a and b, are de? NOTE 28—For a given target size, the MDTD is aastm minimum temperature difference between the target and its background at which the observer can detect the target. In an Atm tube, the anode carries the target. SI unit of luminous? Krypton 85—a tracer gas used to test for leakage when the radioisotope leak test method is used.


ASTM E – 04 Standard Terminology for Nondestructive Examinations

The 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 energy source active or passive may be a source of heat, satm energy vibration or fatigue testingelectrical current, or any other form of energy. False indications are non-relevant.

The standard target is a circle whose size is given by its angular subtense, and both target and background are isothermal blackbodies. This enables the individual leaks to be located. Normally expressed in decibel per unit length.

ASTM E – 18a Standard Terminology for Nondestructive Examinations

AE signal start—the beginning of an AE signal as recognized by the system processor, usually de? In the free state outside of the nucleus, the neutron is unstable having a half-life of approximately 10 min. The process is also termed wash. 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. NOTE 2—Examples include utilization of X-rays or ultrasonic waves for the purpose of determining directly or by calculation?
