What is ISO/TS 13434 about?
ISO/TS 13434 is an international standard that provides guidelines for the assessment of the durability of geosynthetics, the object of which is to provide the design engineer with the necessary information, generally defined as changes in material properties or as partial safety factors, to ensure that the expected design life of a geosynthetic can be achieved with confidence.
NOTE: ISO/TS 13434 is applicable to the durability of geosynthetics and not to the durability of the geotechnical structure as a whole.
NOTE: ISO/TS 13434 is not applicable to products designed to survive for only a limited time, such as erosion-control fabric based on natural fibres.
Who is ISO/TS 13434 for?
ISO/TS 13434 on geosynthetics is useful for:
- Civil engineers
- Manufacturers and suppliers of geosynthetic products
Why should you use ISO/TS 13434?
A geosynthetic is a generic term describing a product, where at least one of the components is made from a synthetic or natural polymer, in the form of a sheet, a strip or a three-dimensional structure, used in contact with soil and/or other materials in geotechnical and civil engineering applications.
ISO/TS 13434 provides the general procedure for manufacturing geosynthetics to understand and assess the evolution of the functional properties over the entire design life.
ISO/TS 13434 also provides the available and required properties of a geosynthetic during storage and transportation, construction, backfilling and use.
The design life, margin of safety, end of life and durability assessment of a structure using a geosynthetic is specified in ISO/TS 13434.
ISO/TS 13434 gives the types of geosynthetic such as polymeric durability considerations and individual polymer types giving the typical physical properties of polymeric geosynthetics.
ISO/TS 13434 provides the knowledge of typical additives used in the production of geosynthetics as it plays a major role in polymer stabilization which includes antioxidants, acid scavengers, metal ion deactivators, UV stabilizers, lubricants, plasticizers, lubricants, mineral fillers and scrims.
Overall, ISO/TS 13434 lets you manufacture geosynthetic products by knowing the procedure for assessment of durability considering all the chemical and physical processes that could, potentially, affect the properties of geosynthetic over its service lifetime and ensure the quality of both design and installation.
