TS EN ISO 10318-1

TS EN ISO 10318-1 is the first part of the geosynthetics terminology standard and brings together the terms and definitions used across this technical field. It supports a common language for geotextiles, geogrids, geomembranes and related geosynthetic products, helping engineers, laboratories and specifiers use the same concepts consistently in design, testing and technical documentation.

How the terminology framework is organised

The focus of this part is on terms related to functions, products, properties and other concepts used in geosynthetics International Standards. Rather than prescribing a particular test method, it establishes the vocabulary framework; definitions for terms not included here can be found in the relevant International Standards that describe appropriate test methods. In practice, terminology standards reduce ambiguity and make it easier to distinguish between related product families and performance concepts.

Why geosynthetics need a dedicated vocabulary

Geosynthetics are polymer-based materials used in geotechnical engineering, transport infrastructure, environmental protection and drainage applications. They may serve as separators, filters, drains, reinforcements, barriers or protection layers. Because the same material family can perform several different functions, it is important to distinguish whether a term refers to the product form itself or to the function it provides. TS EN ISO 10318-1 provides the shared terminology that supports that distinction.

This record reflects the 2015 edition adopted as EN ISO 10318-1 and later withdrawn, while still representing an important reference point for understanding the core terminology of the geosynthetics domain.
