Overview

EN ISO 25178-1:2016 - "Geometrical product specifications (GPS) - Surface texture: Areal - Part 1: Indication of surface texture" defines how to indicate areal (3D) surface texture requirements in technical product documentation. Published by CEN as the European adoption of ISO 25178-1:2016, this standard specifies the graphical symbols, composition rules and annotation practices used on drawings, specifications, contracts and reports to make areal surface texture requirements unambiguous.

Keywords: EN ISO 25178-1:2016, surface texture, areal, GPS, graphical symbols, technical product documentation.

Key topics

Scope and purpose: Rules for indicating areal surface texture requirements by graphical symbols in technical documentation.

Graphical symbols: Uses symbols similar to ISO 1302 with a distinguishing rhomb to identify areal surface texture; expanded symbols indicate whether material removal is permitted or not. An “all-around” modifier (circle) can mark integral features.

Composition of complete symbols: Specifies positions for information items (e.g., parameter, tolerances, modifiers) so annotations are clear and consistent.

Indication of parameters and tolerances: Rules for defining which areal surface texture parameters apply and how tolerances are shown to ensure measurable, enforceable requirements.

Orientation and evaluation area: Guidance on evaluation-area orientation, intersection-plane indicators and coordinate-system declaration to avoid ambiguity.

Digital product definition: Addresses use in digital CAD/PDM environments (see ISO 16792 compatibility).

Normative annexes: Includes proportions/dimensions of symbols, examples for unambiguous specification, recommended procedures for intersection planes and relation to the GPS matrix model.

Applications

Engineering drawings and specifications where 3D surface texture matters (functional surfaces, sealing faces, optical components).

Manufacturing and process planning to communicate whether material removal is permitted or required.

Quality control, inspection planning and metrology reporting to specify which areal parameters and tolerances to measure.

CAD/PDM and digital product-definition workflows that embed surface texture requirements in 3D models and technical data.

Suppliers, OEMs and contract documents requiring consistent, unambiguous surface texture communication.

ISO 1302 (surface texture indication - legacy 2D symbols)

ISO 1101 (geometrical tolerancing)

ISO 16792 (digital product definition)

Using EN ISO 25178-1:2016 ensures consistent, machine-readable and legally defensible communication of areal surface texture requirements across design, manufacturing and inspection.
