E127-05 Standard Practice for Fabricating and Checking Aluminum Alloy Ultrasonic Standard Reference Blocks
Published By | Publication Date | Number of Pages |
ASTM | 2005 | 14 |
1.1 This practice covers a procedure for fabricating aluminum alloy ultrasonic standard reference blocks that can be used for checking performance of ultrasonic testing equipment and for standardization and control of ultrasonic tests of aluminum alloy products using pulsed longitudinal waves introduced into test material either by the direct-contact method or by the immersion method. A recommended procedure for checking blocks is described and calibration data for a number of reference blocks are tabulated. Statements concerning procedures are provided without a discussion of the technical background for the preference. The necessary technical background can be found in Refs. (1-15) .
.
Note 1Practice E 428 and Guide E 1158 also describe procedures for selecting material, fabricating blocks, and checking response. Unlike this practice, there is no requirement for evaluation relative to a specified standard target.
1.2 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.
