Standard Practice for Ultrasonic Examination of Austenitic Steel Forgings
|Publication Date:||1 March 2012|
This practice2 covers straight and angle beam contact, pulse-echo ultrasonic examination of austenitic steel forgings produced in accordance with Practice A388/A388M and Specifications A965/A965M and A1049/A1049M.
Ultrasonic examination of nonmagnetic retaining ring forgings should be made to Practice A531/A531M rather than this practice.
Supplementary requirements of an optional nature are provided for use at the option of the purchaser. The supplementary requirements shall apply only when specified individually by the purchaser in the purchase order or contract.
This practice is expressed in inch-pound and SI units; however, unless the purchase order or contract specifies the applicable "M" specification designation (SI units), the inchpound units shall apply. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the practice, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
*A Summary of Changes section appears at the end of this standard.
