Описание (английский):

ISO 13715:2017 specifies rules for the indication and dimensioning of undefined edges in technical product and dimensions. The proportions and dimensions of the graphical symbols to be used are also specified. In cases where the geometrically defined shape of an edge (for example, 1 × 45°) is required, the general dimensioning principles given in ISO 129‑1 apply.

Abstract

Overview

Key topics and technical requirements

Scope and purpose: Controls deviations at edges that cannot be expressed by ideal geometry - e.g., undercut (material removed) and passing (excess material such as burrs or flash).
Basic graphical indication: A standardized symbol (with proportions given in Annex A) must be readable from the bottom of the drawing. Additional information is placed in defined symbol areas.
Type indication: Use symbol elements + (plus) for permitted passing, − (minus) for required undercut, or ± when both directions are allowed (± requires size specification).
Size/dimensioning: Maximum deviations are indicated numerically after the symbol element. Single positive or negative limits imply the other limit is zero; two limits may be shown as upper/lower deviations.
Direction and asymmetry: Rules for indicating direction of passing or undercut (single-direction and asymmetrical indications). Direction cannot be specified for non‑90° angles.
Location conventions: Symbols may be applied individually (to a line or point), to limited areas (long-dashed-dotted line per ISO 128‑24), or generally for all edges (placed near title block or notes).
Illustrative guidance: Annex B provides examples; figures in Clause 4 show application scenarios and terminology (undercut, passing, sharp edge).

Practical applications and users

ISO 13715:2017 is used to:

Communicate required edge conditions on mechanical and product drawings.
Specify acceptable burrs, flashes, undercuts and passes for manufacturing and inspection.
Harmonize drawing interpretation between design, manufacturing, and quality control.

Primary users:

Mechanical design engineers and CAD drafters
Manufacturing engineers and machinists
Quality inspectors and metrology labs
Technical illustrators and standards coordinators

ISO 129‑1 - General dimensioning principles (for geometrically defined edges)
ISO 128‑22 / ISO 128‑24 - Line types and drawing conventions
ISO 1101 - Geometrical product specifications (used for “between” symbols)

Using ISO 13715 improves clarity of engineering drawings, reduces manufacturing errors related to edge conditions, and supports consistent quality inspection.
