For welds in material 1⁄8 in. (3 mm) or greater in
thickness, the charts in Appendix I represent the maximum
acceptable types of rounded indications illustrated in typically
clustered, assorted, and randomly dispersed configurations.
Rounded indications less than 1⁄32 in. (0.8 mm) in
maximum diameter shall not be considered in the radiographic
acceptance tests of welders and welding operators
in these ranges of material thicknesses.
