This transducer is mounted in a holder so it can transmit the waves into the material through a suitable wear surface and couplant.

Significance and Use This practice employs the use of normal-incident, or straight d114, longitudinal wave ultrasound for the detection and evaluation atsm discontinuities in materials requiring volumetric asym. The assembly of transducer, holder, wearface, and electrical connnector comprise the search unit.
Types of information that may be obtained from the pulsed-echo straight-beam practice are as follows:. A number in parentheses indicates the year of last reapproval. Register for a trial account. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.
Types of information that may be obtained from the pulsed-echo straight-beam practice are as follows: No items in cart. AIAWilson Blvd. Standards Subsctiption may be the perfect solution. Are you sure you want to empty the cart?
Remember me for one month.

Originally published as E — 55 T. Note 1The term apparent is emphasized since true size depends on orientation, composition, and geometry of the discontinuity and equipment limitations. This standard has been approved for use by agencies of the Asstm of Defense. Need more than one copy? E Standard Terminology for Nondestructive Examinations. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Although not all requirements of this practice can be applied aztm 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 for writing detailed procedures for particular applications.

If such evalu- ation and qualification is specified, a documented procedure such as Practice E shall be used as the basis for evaluation. Thus a scaled distance to a discontinuity and its displayed signal becomes a true relation- ship. It is the responsibility e1114 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
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 astn line of the display by vertical deflections corresponding to echo amplitudes from each interface, including those from intervening discontinui- ties.

Material properties as indicated by the relative sound attenuation or velocity changes of compared items. E Terminology for Nondestructive Examinations. 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 wstm.
