Designation:E11415Standard Practice forUltrasonic Pulse-Echo Straight-Beam Contact Testing1This standard is issued under the fixed designation E114;the number immediately following the designation indicates the year oforiginal adoption or,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 This practice2covers ultrasonic examination of materi-als by the pulse-echo method using straight-beam longitudinalwaves introduced by direct contact of the search unit with thematerial being examined.1.2 This practice shall be applicable to development of anexamination procedure agreed upon by the users of thedocument.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility 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.2.Referenced Documents2.1
