ASTM E2375-16 锻造产品超声波检测标准实践

1.1 Purpose—This practice establishes the minimum requirements for ultrasonic examination of wrought products. NOTE 1—This standard was adopted to replace MIL-STD-2154, 30 Sept. 1982. 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 its use for new, or different applications, or both. 1.2 Application—This practice is applicable for examination of materials such as, wrought metals and wrought metal products having a thickness or cross section equal to 0.250 in. (6.35 mm) or greater. 1.2.1 Wrought Aluminum Alloy Products—Examination shall be in accordance with Practice B594. 1.3 Acceptance Class—When examination is performed in accordance with this practice, engineering drawings, specifications, or other applicable documents shall indicate the acceptance criteria. Five ultrasonic acceptance classes are defined in Table 1. One or more of these classes may be used to establish the acceptance criteria or additional or alternate criteria may be specified. 1.4 Order of Precedence—Contractual requirements and authorized direction from the cognizant engineering organization may add to or modify the requirements of this practice. Otherwise, in the event of conflict between the text of this practice and the references cited herein, the text of this practice takes precedence. Nothing in this practice, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 1.5 Measurement Values—The values stated in inch-pounds are to be regarded as standard. The metric equivalents are in parentheses. 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 and health practices and determine the applicability of regulatory limitations prior to use.
