DAC distance amplitude correction swept gain, time corrected gain, time variable gain, and so forth — electronic change of ampli? Also known as a penetrameter disparaged.

A constant intensity signal, irrespective of the circumferential position of a discontinuity, is indicative of electrical centering. Also called clean-up time. Data may be recorded with a system examination threshold lower than the evaluation threshold. Acoustic emission is the recommended term for general use. The discharge tube is a transparent tube in which the color and form of a cold-cathode discharge without the presence of a magnetic? P—effective pair production content. It is the ratio of the distance between the entrance aperture and the image plane L to the diameter of the entrance aperture D.

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.

NOTE 30—The irradiance varies inversely with the square of the distance; a unique property of point sources. The volume and temperature of the system are held constant during the rate of rise measurement. NC—effective thermal neutron content or neutron radiographic contrast.

NOTE 12—The magnetic constant gm is a scalar quantity differing in value and uniquely determined by each electromagnetic system of units. Leakage rates are expressed in various units such as pascal cubic metres per second or pascal litres per second see Table 3. For eddycurrent testing described herein, the frequency is normally 1 to kHz, inclusive.

For small detectors, the detector angular subtenses or projections, a and b, are de? The numerical value of the mass of a particle in terms of amu is identical with the older atomic weight. Penning gauge—see ionization vacuum gauge. The energy source active or passive may be a source of heat, mechanical energy vibration or fatigue testingelectrical current, or any other form of energy.

The value is expressed in line pairs per millimetre.

V at the sensor, before ampli? In the free state outside of the nucleus, the neutron is unstable having a half-life of approximately 10 min. See also standardization, instrument. Originally approved in Expressed in scale divisions per unit time.

See also halogen leak detector 2. The term is used to describe single crystal piezoelectrics as well as polycrystalline piezoelectrics, such as ferroceramics. P is the percent background exposure caused by pair production in 2 mm of lead. It is, therefore, not proper to translate a numerical setting on one instrument to that of another type. Channels may be processed independently or in predetermined groups having similar sensitivity and frequency characteristics.

For uniformity and consistency in E07 nondestructive testing standards, Committee E07 encourages the use of the term examination and its derivatives when describing the application of nondestructive test methods. The coated surface is placed next to the? This is a variant of the differential amplitude distribution, appropriate for logarithmically windowed data. Phillips ionization gauge—see axtm vacuum gauge.

See minimum detectable leakage rate. The coherence length is related to the width of the spectral line emitted from the laser: Normally expressed in decibel per atsm length.

The EDP point is approximately three times the standard depth of penetration. True attenuation losses may be attributed to the basic mechanisms of absorption and scattering.

Nondestructive Evaluation—see Nondestructive Testing. The mass spectrometer may be used as a vacuum gauge that relates an output which is proportioned to the partial pressure of a speci? Even among instruments of the same design and from the same aetm, sensitivity and threshold settings may vary slightly when detecting the same discontinuity.
