Overview
SIST EN ISO 10320:2019, titled Geosynthetics - Identification on Site, is a European Standard adopted by CEN that defines the requirements for labeling and marking geosynthetic products on delivery and installation sites. This standard ensures that users can positively identify geosynthetics as identical to the ordered goods, even when materials are unwrapped or rolled out. It plays a crucial role in quality assurance and traceability without replacing the technical data sheet or verifying product conformity to technical specifications.
The standard was prepared by ISO Technical Committee TC 221 in collaboration with CEN/TC 189 "Geosynthetics" and supersedes the previous EN ISO 10320:1999 edition. It aligns with global efforts to harmonize geosynthetic identification practices to support construction, engineering, and environmental projects.
Key Topics
-
Purpose of Identification on Site
SIST EN ISO 10320:2019 focuses on providing clear, unambiguous identification of geosynthetics during delivery and installation. The aim is to confirm the goods match the order through labeling and marking visible on-site, ensuring product authenticity and aiding project quality control.
-
Information Required on Delivery
Each unit (e.g., rolls or sheets) of geosynthetics must have affixed identification specifying:
- Manufacturer or supplier name
- Product name and type
- Unique unit identification code/number
- Nominal gross mass (kg)
- Unit dimensions (length × width in meters or item count and area)
- Product classification with ISO 10318-1 & ISO 10318-2 compliant terms and symbols
- Main raw material types for each functional component
- Unique color coding specific to product name and type (if applicable)
-
Product Marking for Installation
Markings must be durable and legible on the product itself to allow identification after packaging removal. Methods include:
- Printing or engraving the product name and type at intervals no greater than 5 meters along the machine direction
- Affixing printed ribbons showing product details or using color markings that correspond to the delivered labels
In cases of product processing (cutting, fabrication), unique identification on individual units remains mandatory.
-
Limitations and Scope
This document specifies identification requirements on-site but does not replace technical data sheets or serve as a tool to verify compliance with technical standards.
Applications
SIST EN ISO 10320:2019 is applicable for all types of geosynthetics used in civil engineering and environmental projects, such as:
- Road Construction – Verification of geotextiles and geomembranes on-site during installation to ensure material integrity and specification conformity.
- Landfill and Waste Containment – Accurate identification supports regulatory compliance and later traceability of containment barriers.
- Erosion Control and Drainage Systems – Reliable marking helps contractors correctly position and identify products during installation and inspection.
- Soil Reinforcement and Stabilization – Ensures the use of correct geosynthetic materials for infrastructure longevity and safety.
- Hydraulic Engineering Projects – Facilitates quality control for geomembranes and related products critical to water containment.
By enabling efficient on-site recognition, this standard reduces risks associated with misidentification that could compromise project safety or performance.
Related Standards
The practice of geosynthetics identification is closely linked with the following standards referenced within SIST EN ISO 10320:2019:
- ISO 10318-1: Geosynthetics – Terms and Definitions
- ISO 10318-2: Geosynthetics – Symbols and Pictograms for Product Classification
- ISO 9863-1: Determination of Thickness for Single Layer Geosynthetics
