Significance and Use This practice employs the use of normal-incident, or straight beam, longitudinal wave ultrasound for the detection and evaluation of discontinuities in materials requiring volumetric examination.
ASTM E 114-95 Ultrasonic Pulse-Echo Straight-Beam Examination by the Contact Method
E — 95 An American National Standard Standard Practice for Ultrasonic Pulse-Echo Straight-Beam Examination by the Contact Method1 This standard is issued under the fixed designation E ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
Copyright Compu-tecture, Inc. E Terminology for Nondestructive Examinations. NOTE 1—When determining the sizes of discontinuities by either of these two practices, only the area of the discontinuity which reflects energy to the search unit is determined.

By adjustment of the sweep range controls, this display can be expanded or contracted to obtain a designated relation between the displayed signals and the material reflectors from which the signal originates.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered e141.
Significance and Use 5. A number in parentheses indicates the year of last reapproval. Types of information that may be obtained from the pulsed-echo straight-beam practice are as follows: There were no books e141 for the applied search filters.
By comparison of the displayed discontinuity signal amplitudes to those from a reference standard, both location and estimated discontinuity size may be determined. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Depth location of discontinuities by calibrating the horizontal scale of the A-scan display. Apparent discontinuity size see Note 1 by comparison of the signal amplitudes from the test piece to the amplitudes obtained from a reference standard.

Discon- tinuities having dimensions exceeding the size of the sound beam can also be estimated by determining the amount of movement of a search unit over the examination surface where a discontinuity signal is maintained.
This transducer is mounted in a holder so it can transmit the waves into the material through a suitable wear surface and couplant.
