ASTM - E545
Standard Test Method for Determining Image Quality in Direct Thermal Neutron Radiographic Examination
|Publication Date:||1 May 2019|
|ICS Code (Non-destructive testing):||19.100|
This test method covers the use of an Image Quality Indicator (IQI) system to determine the relative2 quality of radiographic images produced by direct, thermal neutron radiographic examination. The requirements expressed in this test method are not intended to control the quality level of materials and components.
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.
2 The numerical values obtained in the calculations described herein may vary between different film processing systems, film types, and within one processing system if processing variables change.
