Rotary tools for threaded fasteners - Performance test method

ISO 5393:2017 specifies a laboratory performance test method for power assembly tools (referred throughout the document as "tool") for installing threaded fasteners.ISO 5393:2017 provides a method for the measurement of torque repeatability (scatter)- over a range of torque rates as specified in this document,- over a range of torque adjustment as defined by the manufacturer, and- over a number of operating cycles as defined by the manufacturer.ISO 5393:2017 provides a method for the measurement of the precision of the built-in torque measurement system for tools incorporating such a feature. See Annex E.ISO 5393:2017 gives instructions on equipment parameters, what to test for and how to evaluate and present the test data.ISO 5393:2017 is applicable to tools- of any power source, e.g. pneumatic, hydraulic, and electric, including battery-powered,- which apply torque in a generally continuous manner, and- within the torque range 0,5 Nm to 2 000 Nm. Outside this range, it is acceptable to modify the test method providing that the modification is documented in the test report.ISO 5393:2017 is not applicable to- impact or impulse wrenches,- ratchet wrenches or wrenches with ratcheting clutches, and- other tools which advance fasteners in discontinuous increments, overcoming static friction at each increment.ISO 5393:2017 allows a test to be performed at any test torque level; however, in order to minimize the number of test joints necessary for a wide range of test torque levels, a list of preferred test torque levels is provided in Annex A.

Rotary tools for threaded fasteners - Performance test method

ISO 5393:2017 specifies a laboratory performance test method for power assembly tools (referred throughout the document as "tool") for installing threaded fasteners.

ISO 5393:2017 provides a method for the measurement of torque repeatability (scatter)

- over a range of torque rates as specified in this document,

- over a range of torque adjustment as defined by the manufacturer, and

- over a number of operating cycles as defined by the manufacturer.

ISO 5393:2017 provides a method for the measurement of the precision of the built-in torque measurement system for tools incorporating such a feature. See Annex E.

ISO 5393:2017 gives instructions on equipment parameters, what to test for and how to evaluate and present the test data.

ISO 5393:2017 is applicable to tools

- of any power source, e.g. pneumatic, hydraulic, and electric, including battery-powered,

- which apply torque in a generally continuous manner, and

- within the torque range 0,5 Nm to 2 000 Nm. Outside this range, it is acceptable to modify the test method providing that the modification is documented in the test report.

ISO 5393:2017 is not applicable to

- impact or impulse wrenches,

- ratchet wrenches or wrenches with ratcheting clutches, and

- other tools which advance fasteners in discontinuous increments, overcoming static friction at each increment.

ISO 5393:2017 allows a test to be performed at any test torque level; however, in order to minimize the number of test joints necessary for a wide range of test torque levels, a list of preferred test torque levels is provided in Annex A.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
