1、Designation:E100116Standard Practice forDetection and Evaluation of Discontinuities by theImmersed Pulse-Echo Ultrasonic Method Using LongitudinalWaves1This standard is issued under the fixed designation E1001;the number immediately following the designation indicates the year oforiginal adoption or
2、,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1
3、This practice describes procedures for the ultrasonicexamination of bulk materials or parts by transmitting pulsed,longitudinal waves through a liquid couplant into the materialand observing the indications of reflected waves(see Fig.1).Itcovers only examinations in which one search unit is used asb
4、oth transmitter and receiver(pulse-echo)and in which the partor material being examined is coupled to the part by a liquidcolumn or is totally submerged in the couplant(either methodis considered to be immersion testing).This practice includesgeneral requirements and procedures which may be used for
5、detecting discontinuities and for making a relative or approxi-mate evaluation of the size of discontinuities.1.2 This practice replaces Practice E214 and provides moredetailed procedures for the selection,standardization,andoperation of an examination system and for evaluation of theindications obt
