TSE ISO/TR 5460

TSE ISO/TR 5460 is a technical report that provides guidance on the verification of geometrical tolerancing defined in TS 1304. In technical drawings, form, orientation, location and run-out tolerances control not only size but also the geometric behaviour of a part. Verification therefore involves more than measuring a feature; it also requires understanding the reference system and the rules used to judge the measured result.

How geometric tolerancing is verified

Geometrical tolerancing describes how closely manufactured features must relate to ideal geometric elements. Form tolerances constrain the feature itself; orientation and location tolerances define its angle and position relative to a datum system; run-out tolerances address the behaviour of a rotating surface or axis. This report gives general principles for verifying those tolerances within the framework of TS 1304, helping users understand the logic of measurement, comparison and evaluation.

Why the guidance matters in practice

Guidance of this kind is especially relevant in quality control, metrology and technical drawing interpretation. The same tolerance callout can lead to different outcomes if the datum setup, measurement strategy or interpretation method changes, so the way a feature is referenced and assessed is critical. In general technical terms, this subject sits at the intersection of datum establishment, measurement accessibility, instrument capability and comparison of actual deviation with the tolerance zone. TSE ISO/TR 5460 serves as a guide linked to TS 1304 rather than a standalone definition of the tolerancing system.

• Provides guidance for verifying form, orientation, location and run-out tolerances.
• Linked to the geometrical tolerancing described in TS 1304.
• Aims to support consistent interpretation between drawing, measurement and evaluation.
• Based on ISO/TR 5460:1985.
