Overview
ISO 10320:2019, titled "Geosynthetics - Identification on site," is an essential international standard issued by ISO (International Organization for Standardization). This standard specifies the necessary information that must accompany geosynthetic products to enable users to positively identify them on-site as the exact materials ordered. The standard focuses on clear, unique identification of geosynthetics, including those that are unwrapped or rolled out, ensuring correct usage and installation during construction projects.
While ISO 10320:2019 supports product identification, it does not replace technical data sheets nor qualifies for verifying technical compliance. Instead, it facilitates efficient site management, quality assurance, and traceability of geosynthetic materials delivered and installed.
Key Topics
-
Unique Identification on Delivery
Each geosynthetic unit must be labeled or tagged with the following information at the time of delivery for positive identification:
- Manufacturer and/or supplier details
- Product name and product type (including brand and descriptive codes)
- Unit identification (such as roll numbers or codes for traceability)
- Nominal gross mass in kilograms
- Unit dimensions (length × width) or quantity specifications
- Product classification using ISO 10318-1 and ISO 10318-2 standardized terms and symbols
- Main raw material types used in the product components
- Unique color identification where applicable
-
Product Marking for Installation Identification
The standard mandates that geosynthetics be clearly marked with product name and type in a way that remains legible and durable during installation, even if the original packaging is removed. Markings should:
- Be printed or engraved on the product at regular intervals (not exceeding 5 meters) along the machine direction
- Use printed ribbons or color markings when direct markings are impractical
- Maintain unique identification for units processed or cut prior to delivery
-
Traceability and Quality Control
The identification information supports traceability back to production details such as place and date of manufacture, which is critical for project verification and quality assurance.
Applications
ISO 10320:2019 is widely applicable across various geotechnical and civil engineering domains where geosynthetics are used, such as:
- Road construction and maintenance: Ensuring the proper geotextiles and geomembranes are used on-site to enhance soil stability and drainage.
- Landfill and waste containment: Identification of geosynthetic liners critical for environmental protection compliance.
- Water management systems: Confirming the correct installation of geocomposites and filters in hydraulic applications.
- Erosion control and landscaping: Verifying products used for slope stabilization and soil reinforcement.
- Infrastructure and tunneling projects: Guaranteeing correct geosynthetic materials to match engineering designs.
By applying ISO 10320:2019, project managers, contractors, and regulators benefit from enhanced site inspection efficiency and reduced risk of material misidentification.
Related Standards
ISO 10320:2019 works hand-in-hand with other international standards to ensure complete and consistent geosynthetic quality and terminology management:
- ISO 10318-1: Geosynthetics – Terms and definitions
- ISO 10318-2: Geosynthetics – Symbols and pictograms
- ISO 9863-1: Determination of thickness at specified pressures for geosynthetics
- ISO 9864: Test method for mass per unit area of geotextiles
- ISO/TS 13434: Guidelines for durability assessment of geosynthetics
- EN 14196: Test methods for measuring mass per unit area of clay geosynthetic barriers
These complementary standards support consistent product characterization, quality assurance, and communication across the industry.
