You may delete a document from your Alert Profile at any time. Categories and severity levels for each discontinuity type represented by these reference radiographs are described in 1. 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.
Astm e from any porosity, shrinkage, or other discontinuity will move only slightly, astm e any mottling patterns present will change dramatically. These reference radiographs are intended as a basis from which manufacturers and purchasers may, by mutual agreement, select particular discontinuity classes to serve as standards representing minimum levels of acceptability see Sections 6 and 7.
These changes could include changes in the films or processing chemicals used, changes in the dies or printing for the cardboard mats, etc. Please first verify your email before subscribing to alerts.

Reference radiographs for other steel casting thicknesses may be found in Reference Radiograph standards E and E Severity levels of similar discontinuity categories and energy level range of E or E reference radiographs may alternatively be used, as determined appropriate for the casting service application, if so agreed upon in a purchaser supplier agreement see Section 1 and 5.
