Figure A-131. Low severity corner spall, case 2
(b) Medium severity level (M). One of the three conditions exists:
- Spall is broken into two or more pieces defined by medium severity crack(s), and a few small fragments may be
absent or loose.
- Spall is defined by one server, fragmented crack that may be accompanied by a few hairline cracks.
- Spall has deteriorated to the point where loose material causes some FOD potential (figs. A-132 and A-133).
