significance And Use:

scope:

1.1 This practice covers application details for computed radiology (CR) examination using a process in which photostimulable luminescence is emitted by the penetrating radiation detector, a storage phosphor imaging plate (SPIP). Because the techniques involved and the applications for CR examination are diverse, this practice is not intended to be limiting or restrictive, but rather to address the general applications of the technology and thereby facilitate its use. Refer to Guides E 94 and E 2007, Terminology E 1316, and Practices E 747 and E 1025, and 21 CFR 1020.40 and 29 CFR 1910.96 for additional information and guidance.

1.2 The general principles discussed in this practice apply broadly to penetrating radiation CR systems. However, this document is written specifically for use with X-ray and gamma-ray systems. Other CR systems, such as those employing neutrons, will involve equipment and application details unique to such systems.

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. For specific safety statements, see Section and 21 CFR 1020.40 and 29 CFR 1910.96.

1.3 PurposeThis annex is to be used in conjunction with Practice E 2033. It permits the use of, and gives guidance on, the implementation of CR examination for materials, components, and assemblies, when specified in the contract documents. The requirements described herein allow the use of CR for new applications as well as to replace radiology when inspection coverage, greater throughput, or improved inspection economics can be obtained, provided a satisfactory level of image quality can be demonstrated.

1.4 Application This annex provides guidelines for a written procedure as required in of Practice E 2033. Should the requirements in this annex conflict with any other requirements of Practice E 2033, then this annex takes precedence. The requirements of this annex are intended to control the quality of the examination and not to specify the accept/reject criteria. Accept/reject criteria are provided in other contract documents.

1.5 PurposeThis annex is to be used in conjunction with Practice E 2033. This annex includes application-specific details as may be agreed upon by the purchaser and the supplier of CR examination services.

1.6 Application This annex satisfies the requirements of of Practice E 2033. Should this annex conflict with any other requirements of Practice E 2033, this annex shall prevail. The requirements of this annex are intended to control the quality of the examination and not to specify the accept/reject criteria for the part. Accept/reject criteria are provided in other contract documents.
