Standard Practice for Fabrication of Neutron Radiographic Sensitivity Indicators

Importancia y uso:

5.1 The only truly valid image quality indicator is a material or component, equivalent to the part being neutron radiographed, with a known standard discontinuity, inclusion, omission, or flaw (reference standard comparison part). The SI is designed to substitute for the reference standard, providing qualitative information on hole and gap sensitivity in a single unit. Fabrication in accordance with this practice is vital for accurate and consistent measurements.

5.2 This practice shall be followed for the fabrication of all SIs to be used with Test Method E545 to determine image quality in direct thermal neutron radiography. Devices constructed to previous versions of this practice, or Test Method E545 for devices built between 1981 and 1991, can also be used.
