Full title and description

ISO 5393:2017 — Rotary tools for threaded fasteners — Performance test method. This international standard defines laboratory test methods and reporting procedures to assess the performance of power assembly (rotary) tools used to install threaded fasteners, focusing on measurement of delivered torque and repeatability for tools that apply torque in a generally continuous manner.

Abstract

Specifies a laboratory performance test method for power assembly tools for installing threaded fasteners. The standard gives methods for measuring torque repeatability (scatter) across specified torque rates and adjustment ranges, for a number of operating cycles, and for assessing the precision of built‑in torque measurement systems (see Annex E). It includes equipment parameters, preferred test torque levels (Annex A) and procedures for evaluation and presentation of test data. ISO 5393:2017 applies to tools of any power source (pneumatic, hydraulic, electric including battery) that deliver generally continuous torque, typically in the range 0.5 N·m to 2 000 N·m, and excludes impact/impulse and ratchet-type tools.

Scope

Provides a repeatable laboratory method to evaluate the performance of rotary/power assembly tools used to install threaded fasteners. The method is intended for tools that apply torque continuously and is applicable across a wide torque range (0.5 N·m to 2 000 N·m); it is not intended for impact or impulse wrenches, ratchet wrenches or other discontinuous‑motion fastening tools. The standard allows modifications to test method outside the stated torque range provided such modifications are documented in the test report.

Key topics and requirements

• Measurement of torque repeatability (scatter) across specified torque rates and adjustment settings.
• Procedure for evaluating precision of built‑in torque measurement systems (Annex E).
• Recommended/test torque levels and guidance to minimize number of test joints (Annex A).
• Specification of test equipment parameters, test joint definitions and number of operating cycles.
• Data analysis and presentation requirements (statistical treatment and reporting of repeatability and accuracy).
• Applicability to pneumatic, hydraulic, electric and battery-powered rotary tools within the stated torque range.

Typical use and users

Used by tool manufacturers for design verification and quality declarations, independent test laboratories for performance verification and calibration checks, OEM and assembly‑line quality engineers for supplier evaluation and acceptance testing, procurement/specification teams, and standards bodies or regulators concerned with fastening quality and safety.

FAQ

Q: What is this standard?

A: ISO 5393:2017 is an international test‑method standard that defines laboratory procedures to assess performance (especially torque repeatability and measurement precision) of rotary power tools used to install threaded fasteners.

Q: What does it cover?

A: It covers test setup, equipment parameters, preferred test torque levels, the number of cycles and statistical methods to evaluate torque repeatability and the precision of built‑in torque measurement systems. It applies to tools delivering generally continuous torque in the range 0.5 N·m to 2 000 N·m and excludes impact/impulse and ratcheting tools.

Q: Who typically uses it?

A: Manufacturers, independent test laboratories, OEM quality and production engineers, procurement/specification teams, and conformity assessment bodies use it for product development, acceptance testing and quality assurance.

Q: Is it current or superseded?

A: ISO 5393:2017 is the current edition (Edition 3, 2017). The ISO record shows the edition as 2017‑11 and indicates the publication was recorded on 6 December 2017; the standard was last reviewed and confirmed by ISO in 2023, so the 2017 edition remains current.

Q: Is it part of a series?

A: It is part of the family of standards maintained by ISO/TC 118 dealing with hand-held and power assembly tools and their testing. Related standards include the ISO 6789 series (hand torque tools and calibration) and other ISO/TC 118 deliverables addressing tool dimensions, performance and calibration.

Q: What are the key keywords?

A: Torque repeatability, performance test, rotary tools, power assembly tools, threaded fasteners, torque measurement, calibration, pneumatic tools, electric tools.
