Description

ASTM E1955-20

Active Standard: Standard Radiographic Examination for Soundness of Welds in Steel by Comparison to Graded ASTM Reference Radiographs

ASTM E1955

Scope

1.1 This standard covers requirements for radiographic examination for soundness of welds in fabricated steel by comparison to selected severity levels of Reference Radiographs E390, Vol II. The base material varies from greater than 0.25 to 3 in. (6.4–76 mm) inclusive in thickness. Volume II is applicable. This standard is not suitable for shipyard use.

Note 1: This standard was adopted to replace Mil-Std. 1264-B, entitled “Radiographic Inspection For Soundness of Welds In Steel By Comparison To Graded ASTM E390 Reference Radiographs,” dated 18 January, 1989. This standard is intended to be used for the same applications as the document which it replaced. Users should carefully review its requirements when considering the standard’s use for new and/or different applications.

1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.3 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.

1.4 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.
