(Practice)Standard Practice for Digital Radiography of Cast Metallic Implants
Standard Practice for Digital Radiography of Cast Metallic Implants
SIGNIFICANCE AND USE
4.1 The requirements expressed in this practice are intended to control the quality of the digital radiographic image of cast metallic surgical implants.
SCOPE
1.1 This practice covers the procedure for digital radiographic testing of cast metallic surgical implants and related weldments.
1.2 Digital X-ray is an alternative method for radiography of cast metallic surgical implants and related weldments (see Practice F629).
1.3 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.
1.4 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.
1.5 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.
