| Note. | The
bending test shall be done by bending a test specimen by 180º at a right
angle to the rolling direction. The outside of the bend shall be free from exfoliation
of the coating and from cracking and breaking of base metal. This dose not apply
to those parts of the specimen that are within 7mm of either edge. |
