ASTM E3517/E3517M - 26

1.1 This practice covers procedures for evaluating length and vertical extent sizes of flaws in metal weldments using the post processing algorithms referred to as total focusing method (Note 1).

1.2 This practice describes procedures to determine remaining ligaments associated with flaws in metal weldments.

1.3 This practice uses phased-array ultrasonic systems using either full matrix capture (FMC) or plane wave imaging (PWI) as data acquisition methods.

1.4 This practice does not specify accept-reject criteria.

1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard.

1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
