I think ASE do have the spec. on this criteria, it have been aligned with Ka / Dl to have limit sample.
Reference to these defect photos, It is hard to have a clear decision, it look like some SR surface issues.
For my suggestion:
If it is dent with depth as the sample 2, it is suggested to reject on either condition.
If it is contamination do not have any depth as the sample 1, it is
suggested to reject on size >0.15mm size /diameter > 0.15mm ( supposed
it is confirmed by microscope) seen by 30cm naked eye
