Severity levels of similar discontinuity categories and energy level range of E reference radiographs may alternatively be used, as determined appropriate ashm the casting service application, if so agreed upon in the purchaser supplier agreement see Note 2 and 5. The xstm document is also updated by inclusion of several recognized shrinkage or C categories and by elimination of the crack and hot tear categories except for one example of each of these discontinuity types.

Note 2-The illustrations consist of the following: Top Categories Terms of Use. The reference radiographs consist of the following: Reference Radiograph standards E and E provide some overlap of severity levels for similar discontinuity categories within the same energy level range see 4.

Section 9 addresses purchaser supplier requisites for where weld repairs may be required. Each set is for comparison only with radiographs produced with equivalent radiation.

Indications from any porosity, shrinkage, or other discontinuity will move only slightly, while any mottling patterns ee446 will change dramatically. If the indication does not appear on the surface, that indication shall be considered shrinkage. Each set consists of 6 categories of graded discontinuities in increasing severity level and 4 categories of ungraded discontinuites furnished as examples only, as follows:.
