CEN/TC 189/WG 2 - Terminology, identification, sampling and classification

This document establishes general principles for the sampling of geosynthetics delivered to construction sites, and for the preparation of test specimens from the samples.
The sampling principles are applicable to geosynthetics supplied in rolls or expandable panels.
NOTE            ISO 186 can be used for products supplied in sheet form.
The specimen-preparation principles are applicable to all 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 European Standard describes a test method for the laboratory determination of the mass per unit area of a sample of clay geosynthetic barrier (GBR-C) in the condition as received.
Since manufacturers quote mass per unit area at a given moisture content, it is necessary to measure the moisture content.

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.

ISO 9864:2005 specifies a method for the determination of mass per unit area of geotextiles and geotextile-related products for identification purposes and for use in technical data sheets.
The method is applicable to all geotextiles and geotextile-related products.

ISO 9862:2005 establishes general principles for the sampling of geosynthetics delivered to construction sites, and for the preparation of test specimens from the samples.
The sampling principles are applicable to geosynthetics supplied in rolls.
The specimen-preparation principles are applicable to all geosynthetics.

Specifies a method for the determination of the thickness of single layers of multilayer geotextiles at specified pressures.

This European Standard specifies the information accompanying geotextiles and geotextile-related products 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 geotextiles, is an important aim of this standard. The information specified does not replace that on a technical data sheet, and cannot be used to verify the compliance of the product with the technical requirements.

ISO 9863-1:2005 specifies a method for the determination of the thickness of geosynthetics at specified pressures and defines the pressure at which the nominal 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.

ISO 10318:2005 defines terms related to functions, products, properties and other terms, as well as symbols applying to geosynthetics. Definitions of terms not included in ISO 10318:2005 may be found in the standards describing appropriate test methods.

This European standard specifies a method for the determination of the thickness  of geotextiles and geotextile-related products at specified pressures and defines the pressure at which the nominal thickness is determined. The method is applicable to all geotextiles and geotextile-related products. Note: The thickness of geotextiles and geotextile-related products should normally be determined by measuring one layer of the product. When two or more layers are used on top of each other in a design, a test may be made in accordance with this European standard with the agreed number of layers.

This European standard establishes general principles for sampling of geotextiles and geotextile-related products and preparation of test specimens from the samples. The sampling principles are applicable to geotextiles and geotextile-related products supplied in rolls to construction sites. Note: EN 20186 may be used for products supplied in other forms. The specimen-preparation   principles are applicable to all geotextiles and geotextile-related products.

This European standard specifies a method for the determination of mass per unit  area of geotextiles and geotextile-related products for identification purposes and for use in technical data sheets. The method is applicable to all geotextiles and geotextile-related products.

The standard specifies the identification process for geotextiles and geotextile-related products
