SIGNIFICANCE AND USE
5.1 This practice establishes the basic parameters for the application and control of the CR examination method. This practice is written so it can be specified on the engineering drawing, specification, or contract.
5.2 Weld Examination—Additional information on weld examination may be found in Practice E1032, ISO 17636-2, or both.
5.3 Casting Examination—Additional information on casting examination may be found in Practice E1030.
5.4 Electronic Components—Radiographic examination of electronic components shall comply with Practice E1161.
5.5 Part-Specific Examination Technique—A detailed written procedure in the form of a part-specific examination technique (7.5) shall be documented for each part, or group of parts, and shall be approved by the Cognizant Radiographic Level 3.
5.6 Personnel Qualification—Personnel performing examinations to this practice shall be qualified in accordance with ISO 9712, NAS 410, EN 4179, ANSI/ASNT CP 189, or SNT-TC-1A and certified by the employer or certifying agency as applicable. Other equivalent qualification documents may be used when specified on the contract or purchase order. The applicable revision shall be the latest unless otherwise specified in the contractual agreement between parties.
5.7 System Qualification—All CR systems shall be qualified for their intended use. System qualification requirements are specified in subsection 7.1.
5.8 Process Control—All CR systems shall be monitored for long term stability (process control) as specified in subsection 7.1.4.
5.9 Preventative Maintenance—All CR systems and X-ray machines require periodic maintenance to ensure proper functionality. Preventative maintenance requirements are specified in subsection 6.2.
5.10 Environmental Conditions—CR systems should be operated within environmental conditions that are in compliance with manufacturer’s stated acceptable environmental conditions, e.g., temperature and humidity. When CR systems are operated outsid...
SCOPE
1.1 This practice establishes the minimum requirements for computed radiographic (CR) examination for metallic and nonmetallic materials using X-ray or gamma radiation.
1.2 Applicability—The requirements in this practice are intended to control the quality of computed radiographic examinations and are not intended to establish acceptance criteria for parts or materials.
1.3 Basis of Application—The requirements of this practice, Practice E2445 and E2446 shall be used together. The requirements of Practice E2445 will provide the baseline performance evaluation and long term stability test procedures for the CR system. Practice E2446 CR performance levels are recommended in Table 1. The user of the CR system shall establish a written procedure that addresses the specific requirements and tests to be used in their application and shall be approved by the Cognizant Radiographic Level 3 before examination of production hardware. The items that shall be determined and addressed in the written procedure are:
(a) Personnel qualification and certification.
(b) Minimum effective pixel coverage appropriate to the acceptance criteria and to meet the radiographic image quality level requirements of Table 1.
(c) Additional tests per Practice E2445 deemed appropriate.
(d) Organizations using a gamma source or radiation energy above 320 kV may need to modify the E2445 tests, gauges, or both.
(e) Maximum allowed unsharpness when other than Table 1.
(f) The method used to provide image traceability to the part and the examination facility.
1.3.1 This practice also requires the user to perform a system qualification suitable for its intended purpose and to issue a system qualification report (see subsection 7.1). Additionally, the user shall develop part specific inspection procedures (see subsections 5.5 and 7.5).
1.4 Units—The values stated in either SI units or inch-pound units are to be regarded separately as s...

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
