ISO 13715 Technical drawings - Edges of undefined shape - Vocabulary and indications

Oct 23, 2026

Upload by lilac

ISO 13715 defines vocabulary and graphic indications for representing edge states in technical drawings when the ideal geometric form cannot be shown without deviation. It addresses external edges with burrs or sharp edges of limited extent and internal edges with a passing condition. The standard provides guidelines and rules so delivered parts can match the required edge treatments rather than relying on machine-delivered default conditions. It includes normative and informative annex content covering graphical symbol proportions, recommended edge sizes, and relationships between part edges and corners.

FAQs

What problem does ISO 13715 address in technical drawings?

It addresses the mismatch between the edge states required for part function or safety and the default state delivered directly from the machine when edge treatments are not specified in drawings or related documentation.

What kinds of edge states does the standard aim to indicate?

It covers external edges such as burr-free or sharp edges, burrs of limited size, and internal edges with a passing condition.

What are the main parts of the standard’s structure?

It includes scope, normative references, terms and definitions, indications on drawings, an example, plus annexes A (normative) and B/C (informative) with symbol proportions, recommended edge sizes, and relationships between edges and corners.
