Standard Practice for Use of Rubber-Cord Pie Disk to Demonstrate the Discernment Capability of a Tire X-ray Imaging System

Importancia y uso:

5.1 All X-ray systems are subject to changing efficiencies, so a practice for checking the overall operation is needed. This practice will assure the operator of an optimized image when ambient conditions are controlled and the X-ray high voltage generator is adjusted as prescribed.

5.2 The densities of some tire cord materials are very close to that of the rubber matrix in which they are enclosed, so the resolving capability of an X-ray system is critical to the detection of abnormalities. The rubber-cord pie disk provides a means for optimizing the resolving power in a particular apparatus and for comparing its performance over any period of time.

5.3 The rubber-cord pie disk can be used to compare the performances of X-ray systems in different laboratories. It can also be used in special cases to optimize system performance for a particular sector or cord-type, as may be required for examining a specific tire.
