# Summary for ISO 5393

A | Upper/Lower test torque level | B | Hard/Soft combined statistics values

- Upper/Lower test torque level: the Upper/Lower test torque level defines the main statistics values coming from the ISO 5393 Inspection execution.

  - Mean torque: mean value according to ISO norm.

  - Range: range value according to ISO norm.

  - Standard deviation: measure of the dispersion based on the mean-squared deviation, according to ISO norm.

  - 6σ torque scatter: predictable range of torque over which a tool runs through a single torque-rate joint under controlled conditions, according to ISO norm.

  - 6σ scatter % of mean torque: single numerical value designating the torque capability of a tool run on a single torque-rate joint under controlled conditions, according to ISO norm.

- Hard/Soft combined statistics values: the Hard/Soft combined statistics values define the combination of the statistic values coming from the execution of the Hard and Soft sessions of ISO 5393 Inspection.

  - Combined mean torque: midpoint of the combined torque scatter of a tool between the lowest and the highest predictable torque readings, according to ISO norm.

  - Mean shift: difference in mean torque of a tool run on a threaded joints of two different torque rates at the same setting of the tool torque adjustment, according to ISO norm.

  - Combined torque scatter: the total probable range of torque of a tool run on all joints used in practice at the same setting of the tool torque adjustment, according to ISO norm.

  - Combined torque scatter % of combined mean torque: single numerical value designating the torque capability of a tool run on joints of varying torque rate, according to ISO norm.
