(Practice)Standard Practice for Radiography of Cast Metallic Surgical Implants
Standard Practice for Radiography of Cast Metallic Surgical Implants
SIGNIFICANCE AND USE
The requirements in this practice are intended to control the quality of the radiographic image of cast metallic surgical implants and related weldments.
SCOPE
1.1 This practice covers the procedure for radiographic testing of cast metallic surgical implants and related weldments.
1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
