and measurement when using the HAL technique. Height determinations made with the HAL and 70-degree shear techniques should always be confirmed using complementary methods. B.7.3 Evaluation. The characterization and sizing techniques specified herein have limitations and errors may occur that could lead to uncertainty in the accuracy of the discontinuity evaluation. Some discontinuities cannot be accurately sized because of discontinuity or component geometry, and in these cases, the inspector should report that the discontinuity height could not be determined.
B.8 RECORDS.
B.8.1 Reporting Requirements. The following information and suggested format or an equivalent detailed report shall be prepared for each discontinuity. In addition, comments to explain the condition or suspected condition of a given discontinuity should be noted, for example, “thinning/corrosion , ” “lamination/inclusion,” or “crack/crack - like”. If conflicting information makes the characterization uncertain, report the condition as “unknown”. Describe in the summary block if the discontinuity appears to be a crack/crack-like discontinuity open to the back surface, an embedded inclusion, base material discontinuity, or a thinning/corrosion condition on the back surface of the wall.
