SIST EN 13361:2018

EN 13361:2018 (E) 4 Introduction This document allows manufacturers to describe geosynthetic barriers on the basis of declared values for characteristics relevant to the intended use and if tested to the specified method. It also includes procedures for assessment and verification of constancy of performance (AVCP) including the factory production control. This document can also be used by designers, end-users and other interested parties as a tool to define relevant and appropriate characteristics for specifications. Tests for some non-mandated characteristics are still under study and will be included when the standard is revised. The term “product” used in this document refers to a geosynthetic barrier, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers. This document is part of a group of standards, addressing the requirements for geosynthetic barriers when used in a specific application. Particular application cases can contain requirements about additional properties and – preferably standardized – test methods, if they are technically relevant and not conflicting with European Standards. The design life of the product should be determined, since its function may be temporary, as construction expediency, or permanent, for the lifetime of the structure. SIST EN 13361:2018

EN 13361:2018 (E) 5 1 Scope This document specifies the characteristics of geosynthetic barriers, including polymeric geosynthetic barriers, clay geosynthetic barriers and bituminous geosynthetic barriers, when used as fluid barriers and separation layer for water, in the construction of reservoirs and dams, and the appropriate test methods to determine these characteristics. The intended use of these products is to control the leakage of potable, fresh or saline water through the construction. This document is not applicable to geotextiles or geotextile-related products, as defined in EN ISO 10318-1. This document provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard including factory production control procedures. This document defines characteristics to be considered with regard to the presentation of performance. NOTE Where potable water is or can be in direct contact with the product, other relevant standards, requirements and/or regulations can be considered for the design. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Damage during installation has not been addressed in this document. 4.2 Types of application 4.2.1 General It is not normally advisable to install a geosynthetic barrier on the downstream face of a dam. Special consideration should be given to any geosynthetic barrier installed on the downstream face of a dam. The applications described in this document do not include such situations. 4.2.2 Application 1: “covered in service” In these applications, the GBR is laid on the upstream face of a dam or in a reservoir and is covered in service with a revetment or other protective layers.

The list of characteristics in Table 1 includes those relevant to all conditions of use (A) (essential characteristics are listed in Table ZA.1), and those relevant to specific conditions of use (S). The indication “–” means that the characteristic is not relevant for that function. Where, for the same property, data for more than one function shall be provided, the following ranking order shall be observed: A overrules S, and S overrules “–”. The functions and conditions of use, corresponding with the S-coded characteristics in Table 1, are specified in 4.4. The performances of the characteristics shall be given on basis of the results of tests specified in this document and, where relevant, in accordance with 5.1. Information on how functioning joints can be made should be provided.

Where products are jointed in the factory the liquid tightness and if relevant the strength of the joints shall be tested and data presented. SIST EN 13361:2018
