oSIST prEN ISO 10318-2:2025

Overview

oSIST prEN ISO 10318-2:2025 - Geosynthetics - Part 2: Symbols and pictograms defines standardized property symbols, graphical symbols, and pictograms used in European and international standards for geosynthetics. Developed by the Slovenian Institute for Standardization (SIST) in alignment with ISO/TC 221, this document directly supports clear communication and harmonization across the global geosynthetics industry. By providing a universally recognized system of symbols and pictograms, oSIST prEN ISO 10318-2:2025 enhances the understanding, specification, and documentation of geosynthetics in design, manufacturing, testing, and construction.

Key Topics

• Property Symbols: Defines consistent symbols for physical, hydraulic, and mechanical properties of geosynthetics, such as thickness (d), mass per unit area (ρ), permeability coefficient (k), and tensile stress (σ).
• Graphical Symbols and Pictograms: Establishes pictograms for different geosynthetic products (e.g., geotextiles, geomembranes, geogrids) and their typical functions (such as separation, filtration, reinforcement, drainage).
• Application Area Icons: Provides application-specific symbols for clear identification of typical geosynthetics uses, including reservoirs, transportation infrastructure, erosion control, and waterproofing.
• Cross-standard Consistency: Aligns with relevant EN and ISO geosynthetics standards, contributing to global harmonization and interoperability across technical documents, specifications, and testing records.
• Reference to Related Definitions: Points users to additional International Standards for definitions of any property symbols or pictograms not directly covered in this part.

Applications

The standardized symbols and pictograms described in oSIST prEN ISO 10318-2:2025 are essential tools for a wide range of geosynthetics-related tasks and stakeholders:

• Technical Documentation: Ensures clarity and reduces misinterpretation in specifications, test reports, compliance documents, and manuals.
• Design and Engineering: Facilitates communication between designers, engineers, and contractors by using universally recognized symbols in designs, drawings, and project documentation.
• Construction and Installation: Supports field teams with clear pictograms that identify geosynthetic functions and product types, improving on-site decision-making and quality assurance.
• Testing and Quality Control: Provides consistency for laboratory reports and certifications, promoting comparability and regulatory acceptance.
• Training and Education: Acts as a reference in geosynthetics training, ensuring new practitioners understand industry-standard terminology and visual language.
• International Trade and Regulation: Promotes cross-border acceptance and regulatory compliance by aligning with ISO and EN documentation expectations.

Related Standards

For comprehensive understanding and correct application, oSIST prEN ISO 10318-2:2025 should be used alongside other key geosynthetics standards, including:

• ISO 10318-1: Geosynthetics - Part 1: Vocabulary - Definitions of general terms and primary properties.
• ISO 9863-1: Geosynthetics – Determination of thickness at specified pressures.
• Related EN and ISO standards: Covering detailed test methods, product specifications, and additional vocabulary relevant to geotextiles, geomembranes, geogrids, and other geosynthetics.
• ICS Codes: 01.040.59 (Textile technology vocabularies), 01.080.01 (Graphical symbols in general), 59.080.70 (Geotextiles).

By adopting oSIST prEN ISO 10318-2:2025, organizations involved in geosynthetics manufacturing, design, testing, and construction can ensure greater clarity, efficiency, and global compatibility in their technical communications and documentation.
