A superscript epsilon e indicates an editorial change since the last revision or reapproval. Note 1The term apparent is emphasized since true size depends on orientation, composition, and geometry of the discontinuity and equipment limitations.
The practice or standard used and its applicable revision shall be specified in the contractual agreement between the using parties. There were no books found for the applied search filters. If you like to setup a quick demo, let us know at zstm madcad. Click here to download full list of books.
These echoes return to the search unit, where they are converted from mechanical to electrical energy and are ampli- fied by a receiver. By comparison of e114 displayed discontinuity signal amplitudes to those from a reference standard, both location and estimated discontinuity size may be determined.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.

ASTM E 114-95 Ultrasonic Pulse-Echo Straight-Beam Examination by the Contact Method
As the voice of the U. 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.
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 amplified echoes signals are usually presented in an A-scan display, such that the entire round trip of pulsed energy within the resolution of the system may be indicated along the horizontal s114 line of the display by vertical deflections corresponding to echo amplitudes from each interface, including those from intervening discontinui- ties.

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. A number in parentheses indicates the year of last reapproval.

Last previous edition E — Although not all requirements of this practice can be applied universally to all inspection situations and materials, it does provide the basis for establishing contractual criteria between suppliers and purchasers of materials for performing contact longitudinal wave pulse-echo examination and may be used as a guide f114 writing detailed procedures for particular applications.
