ISO/TC 221/WG 2 - Terminology, identification and sampling

This document defines terms related to the functions, products, and properties in geosynthetics, and terms used in International Standards on geosynthetics.

This document specifies a method for the on-site installation and retrieval of geosynthetic samples, irrespective of the particular degradation mechanisms to which they are exposed. The method is also appropriate to test for mechanical damage, much of which occurs during installation, and to provide an owner with information about the state of the geosynthetic product in their structure.

This document specifies the information accompanying geosynthetics to enable the user on site to identify the goods as being identical to the goods ordered. The positive identification, e.g. of unwrapped or rolled-out geosynthetics, is an important aim of this document. The information specified does not replace a technical data sheet and cannot be used to verify the conformance of the product with the technical requirements.

ISO 9863-1:2016 specifies a method for the determination of the thickness of geosynthetics at specified pressures and specified load plate areas or under specified point loads. It defines the pressures or the load at which the thickness is determined. The test results are intended for identification purposes and for use in technical data sheets and/or as part of other test methods, e.g. tests of hydraulic properties. The method is applicable to all geosynthetics.

The intent of ISO 10318-1:2015 is to define terms related to functions, products, properties, and other terms used in EN and ISO geosynthetics standards. Definitions of terms not included in ISO 10318-1:2015 can be found in the International Standards describing appropriate test methods.

The intent of ISO 10318-2:2015 is to define property symbols, graphical symbols, and pictograms used in EN and ISO geosynthetics standards. Definitions of particular or specific symbols and pictograms terms not included in this this part of ISO 10318 can be found in the International Standards describing appropriate test methods.
