FRACTURE TYPES:
1 Reasonably _1I.formed cones on both ends. less than 1 in. (25 mm) of cracking through caps.
2 Well-formed cone on one end, vertical cracks running through caps, no _II-defined cone on other end.
3 Columnar vertical cracking through both ends, no _II-formed cones.
4 Diagonal fracture with no cracking through ends; tap with hammer to distinguish from Type 1.
5 Side fractures at top or bottom (occur commonly with unbonded caps).
