TS EN ISO 10318-2/A1

TS EN ISO 10318-2/A1 is Amendment 1 to TS EN ISO 10318-2, the part of the geosynthetics terminology system devoted to symbols and pictograms. It supports the common graphical language used in EN and ISO standards for geosynthetics by defining property symbols, graphical symbols, and pictograms, and it notes that specific symbols and pictograms not covered in this part may be found in the relevant international test method standards.

How symbols and pictograms support geosynthetics terminology

Geosynthetics are engineered polymer-based products used in contact with soil and related materials for functions such as separation, filtration, drainage, reinforcement, protection, or barrier action. In technical documents, symbols help compress these ideas into a consistent shorthand for properties, test outcomes, and product functions. The distinction between graphical symbols and pictograms matters: graphical symbols typically encode technical information in a standardized form, while pictograms provide a more visual, immediately recognizable representation.

What this amendment contributes in practice

• It is an amendment to the symbol and pictogram framework used across geosynthetics EN and ISO standards.
• Its scope covers property symbols, graphical symbols, and pictograms.
• For symbols and pictograms not included in this part, the document points users to the relevant international test method standards.
• It should be read as an update to the terminology and representation framework, not as a standalone product standard or test method.

In practice, a standard of this kind improves consistency in drawings, datasheets, reports, and technical labelling. Because geosynthetics cover a wide range of products and functions, shared symbols reduce ambiguity across manufacturers, laboratories, and project teams. As an amendment, this listing should be understood as updating the parent document’s graphical language rather than replacing it.
