Organization: ASTM
Publication Date: 1 October 2020
Status: active
Page Count: 6
ICS Code (Plastics in general): 83.080.01
ICS Code (Pharmaceutics in general): 11.120.01
scope:

These test methods cover the determination of the radiopacity of materials and products utilizing X-ray based techniques, including fluoroscopy, angiography, CT (computed tomography), and DEXA (dual energy X-ray absorptiometry), also known as DXA, The results of these measurements are an indication of the likelihood of locating the product within the human body.

Radiopacity is determined by (a) qualitatively comparing image(s) of a test specimen and a user-defined standard, with or without the use of a body mimic; or (b) quantitatively determining the specific difference in optical density or pixel intensity between the image of a test specimen and the image of a user-defined standard, with or without the use of a body mimic.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

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.

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.
