| Note.: (*) The values
of tensile strength resistance of the classes FC200
and FC 300, refer to tests carried out in specimen
from 30mm diameter bars cast separate from the part.
The chart below shows the values expected for tests
carried out in specimen taken from bars in the medium
section in relation to the gauge. |
