# ISO 5393 parameters

The ISO 5393 test is available only for Power tools.

General category

- Name: type the name of the inspection.

- Barcode identifier: it identifies the inspection. If left blank, the identifier corresponds to the inspection name.

- Measurement device type: STbench is the only measurement device type available for this test strategy.

- Measurement device S/N: type the serial number of the measuring device connected to the device.

- Number of samples: type the number of results to do.

  The number of samples ranges from 5 to 99.

- Tightening direction: from the drop down list select the tightening direction. The available items are Clockwise and Counterclockwise.

- Free rounds: type the number of free rounds the tool performs to reach the proper operating speed before starting the test operation.

Upper torque category

- Upper test torque level: specified upper mean torque level attainable on a low torque-rate joint in accordance with this International Standard.

- Measure angle from: from the drop-down list, select between:

  - One step:the measurement of the angle starts as soon as the Final monitoring torque value is reached.

  - Second step: the measurement of the angle starts in the second step, when the Final angle monitoring torque value is reached.

  - Starting second step: the measurement of the angle starts at the starting of the second step.

- Final angle monitoring torque: type the final angle monitoring torque value.

  The final angle monitoring torque must be equal or higher than the Minimum torque.

- Hard joint angle: the test shall include a joint having a low torque rate and a joint having a high torque rate. On a high torque-rate joint (“hard joint”), the tightening is accomplished in a fraction of a revolution. The high torque-rate joint shall be such that the torque increase from 10% to 100% of the test torque level corresponds to an angular displacement of 27°.

- Soft joint angle: the test shall include a joint having a low torque rate and a joint having a high torque rate. On a low torque-rate joint (“soft joint”), the tightening is usually accomplished with several revolutions of the fastener. The low torque-rate joint shall be such that the torque increase from 10% to 100% of the test torque level corresponds to an angular displacement of not less than 650°.

- Transducer S/N: type the serial number of the transducer linked to the measuring device connected to the device.

- STbench channel: select the STbench channel to use to do the test. The available options are:

  - Manual selection.

  - Number of the STbench channel (from 1 to 8).

Lower torque category

- Lower test torque level: specified lower mean torque level attainable on a low torque-rate joint in accordance with this International Standard.

- Measure angle from: from the drop-down list, select between:

  - One step: the measurement of the angle starts as soon as the Final monitoring torque value is reached.

  - Second step: the measurement of the angle starts in the second step, when the Final angle monitoring torque value is reached.

  - Starting second step: the measurement of the angle starts at the starting of the second step.

- Final angle monitoring torque: type the final angle monitoring torque value.

  The final angle monitoring torque must be equal or higher than the minimum torque.

- Hard joint angle: the test shall include a joint having a low torque rate and a joint having a high torque rate. On a high torque-rate joint (“hard joint”), the tightening is accomplished in a fraction of a revolution. The high torque-rate joint shall be such that the torque increase from 10% to 100% of the test torque level corresponds to an angular displacement of 27°.

- Soft joint angle: the test shall include a joint having a low torque rate and a joint having a high torque rate. On a low torque-rate joint (“soft joint”), the tightening is usually accomplished with several revolutions of the fastener. The low torque-rate joint shall be such that the torque increase from 10% to 100% of the test torque level corresponds to an angular displacement of not less than 650°.

- Transducer S/N: itype the serial number of the transducer linked to the measuring device connected to the device.

- STbench channel: select the STbench channel to use to do the test. The available options are:

  - Manual selection.

  - Number of the STbench channel (from 1 to 8).
