Abstract

1.1 This guide covers procedures for the contact ultrasonic examination of bulk materials or parts by transmitting pulsed ultrasonic waves into the material and observing the indications of reflected waves. This guide covers only examinations in which one search unit is used as both transmitter and receiver (pulse-echo). This guide includes general requirements and procedures that may be used for detectingdiscontinuities, locating depth and distance from a point ofreference and for making a relative or approximate evaluationof the size of discontinuities as compared to a referencestandard.1.2 This guide complements Practice E114 by providingmore detailed procedures for the selection and standardizationof the examination system and for evaluation of the indicationsobtained.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 guide does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this guide to establish the appropriate safety,health, and environmental practices and determine the applicabilityof regulatory limitations prior to use.1.5 This international standard was developed in accordancewith internationally recognized principles on standardizationestablished in the Decision on Principles for theDevelopment of International Standards, Guides and Recommendationsissued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.
