TS EN ISO 10318-2

TS EN ISO 10318-2 is the standard that addresses the symbols and pictograms used within geotextiles and the wider geosynthetics terminology framework. It brings together property symbols, graphical symbols, and pictograms used in EN and ISO geosynthetics standards, helping technical documents, drawings, and data sheets communicate the same meaning consistently.

The role of symbols and pictograms

Geosynthetics are a family of polymer-based products that includes geotextiles, geomembranes, geogrids, and related materials. In this field, symbols are used to express a product property, behavior, or a test-related parameter in a compact visual form. Pictograms support multilingual technical communication by reducing complex wording into clearer visual references. In general technical practice, the value of such symbols lies in making the same concept understandable across different standards and countries.

What this part covers

• It provides a common framework for property symbols, graphical symbols, and pictograms used in EN and ISO geosynthetics standards.
• If a specific symbol or pictogram term is not included here, it may be found in the international standards that describe the relevant test methods.
• This document organizes the visual terminology of geosynthetics; it is not, by itself, a test method standard defining product performance.

From a technical standpoint, the value of a standard like this is consistency in how measured results and product characteristics are represented. For designers, laboratories, manufacturers, and specification writers, symbol consistency improves data comparison, document traceability, and international technical communication. TS EN ISO 10318-2 serves as an important reference for the visual terminology infrastructure used in geosynthetics.
