ISO 10318-2:2015/Amd 1:2018

Overview

ISO 10318-2:2015/Amd 1:2018 is an important amendment to the international standard addressing geosynthetics, specifically focusing on symbols and pictograms. Published by the International Organization for Standardization (ISO), this amendment updates Part 2 of ISO 10318, which standardizes graphical representations used in the geosynthetics industry. These symbols are crucial for ensuring clear communication, consistency, and safety across technical documents, product specifications, and engineering drawings.

This amendment introduces three new pictograms that serve practical purposes in identifying key geosynthetic applications: stabilization, secondary containment, and waterproofing and underground structures. By harmonizing these visual codes, ISO 10318-2 facilitates better understanding among manufacturers, engineers, designers, and regulatory bodies worldwide.

Key Topics

• Standardized Symbols and Pictograms
  The document defines a set of internationally accepted symbols representing geosynthetic products and functions. This amendment adds three specific pictograms for common geosynthetic uses.

• New Pictograms Introduced

  • Stabilization: Symbolizes geosynthetics used to reinforce soil and improve ground stability.
  • Secondary Containment: Represents materials deployed as containment liners or barriers to prevent leakage or contamination.
  • Waterproofing and Underground Structures: Denotes geosynthetics applied for waterproofing solutions and protection of subterranean infrastructure.

• Technical Committee ISO/TC 221
  The amendment was developed by ISO Technical Committee 221, specializing in geosynthetics, ensuring the standard reflects current industry practices and innovations.

• Compliance and Intellectual Property
  The document adheres to ISO/IEC Directives and respects intellectual property rights, providing legal and procedural clarity for users.

Applications

The standardized symbols and pictograms outlined in ISO 10318-2:2015/Amd 1:2018 are integral to numerous geosynthetics applications, enabling consistent labeling and documentation:

• Civil Engineering Projects: Clear graphical representation of geosynthetics used in soil stabilization for embankments, retaining walls, and road construction.
• Environmental Protection: Identification of geosynthetics designed for secondary containment in waste management sites, landfills, and chemical storage facilities.
• Infrastructure Waterproofing: Standardization of icons for waterproofing membranes and geosynthetics that protect tunnels, basements, and underground structures from water ingress.
• Product Manufacturing and Packaging: Facilitates uniform marking and certification, helping manufacturers comply with international standards and improve market clarity.
• Technical Documentation and Design Drawings: Enhances readability and reduces ambiguity in engineering and architectural drawings through universally understood symbols.

Related Standards

ISO 10318-2:2015/Amd 1:2018 complements other standards within the geosynthetics domain and related fields:

• ISO 10318-1:2015 – General terminology for geosynthetics, providing definitions that underpin symbol usage.
• ISO 10318-3 – Specifications and test methods for geosynthetics (where applicable), supporting the standardized communication of product properties.
• ISO/IEC Directives Parts 1 & 2 – Guidelines for the preparation, approval, and maintenance of ISO standards, ensuring consistency and quality.
• ISO 17892 – Geotechnical investigation methods, which often reference geosynthetics in soil stabilization contexts.
• ISO Standards on Environmental Management – Related to containment and pollution prevention systems incorporating geosynthetic materials.

ISO 10318-2:2015/Amd 1:2018 plays a vital role in advancing clear, efficient, and globally recognized communication within the geosynthetics industry. Adopting these updated symbols and pictograms ensures improved safety, regulatory compliance, and interoperability in engineering, manufacturing, and environmental protection sectors worldwide.
