Originally approved in The current may be alternating, recti? Coils of this type are also referred to as inside coils, inserted coils, or bobbin coils. The Phillips ionization gauge is a cold-cathode ionization gauge in which a magnetic? Normally expressed in decibel per unit length. This enables the individual leaks to be located.

Radiographic exposure is commonly expressed in terms of milliampere-seconds or millicurie-hours for a known source-to-? The EDP point is approximately three times the standard depth of penetration. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. NOTE 24—Dynamic range may be stated as the numerical value of the ratio; however, this is usually expressed in decibels.

ASTM E – 18a Standard Terminology for Nondestructive Examinations

A constant intensity signal, irrespective of the circumferential position of a discontinuity, is indicative of electrical centering. This effect generally results in the masking of discontinuities within the affected region. 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?

This type of equipment usually operates at energies between 10 and 31 MEV. This is also called pulse repetition rate.

Standard Terminology for Nondestructive Examinations

For analysis purposes, dependence of measured data on the system examination threshold must be taken into consideration. Various types are distinguished by the method of separating the ions.

These effects include nausea and vomiting, malaise, increased temperature, and blood changes. Also called a sniffing probe. Measurement of travel times for the forward re? The principal types are as follows: 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.

See also comparator coils.

In outdoor applications it usually is de? See also skin effect. The outside of the component is examined for the detection of any leaks. Radiologic Testing RT is often used to examine material to detect internal discontinuities. The numerical value of the mass of a particle in terms of amu is identical with the older atomic weight. See minimum astn leakage rate. Felicity ratio—the ratio of the stress at which the Felicity effect occurs to the previously applied maximum stress.

The purpose of this standard is to promote a clear understanding and interpretation of the NDT standards in which they are used.

The value and dimension of absolute permeability depends on the system of units employed. NOTE 22—In practice, meaningful experimental values can be obtained in an ashm neutron? D i, a numerical value is meaningless unless both the corresponding values of mean excitation level B or H and the excursion range DB or DH are speci?

Acoustic emission is the recommended term for general use. These nondestructive testing NDT methods include: NOTE 16—For the incremental permeabilities? The electrical center may be different from the physical center of the test coil. The common types are listed below: The mass spectrometer may be used as a vacuum gauge that relates an output which is proportioned to the partial pressure of a speci?

If it has been interpreted as relevant, the necessary subsequent evaluation will result in the decision to accept or reject the material. NOTE 17—Sensitivity and threshold settings usually are indicated by arbitrary numbers on the control panel of the testing instrument.

One candela produces 1 lumen of luminous? Felicity effect—the presence of detectable acoustic emission at a? Compounds do not fall under the strict de? The value in decibels dB is 8. See also absolute coil. Astj known as a perfect gas.
