9. Specification of hardenability by a given hardness
between two distance limits
10. Specification of hardenability by a range of
hardness at a given distance from the quenched end

12. Correlation between sub-standard 12.5 mm diameter
and standard 25 mm diameter test piece results
13. Cooling curves along the Jominy test piece giving
the ratio theta/thetaA as a function of time
14. Variation in the cooling rates at approximately 700
deg C, in degrees Celsius per second, of points on
the surface of the Jominy test piece as a function
of their distances from the quenched end
