Overview

EN ISO 9863-1:2016 is an international standard developed by CEN, specifying the methodology for determining the thickness of geosynthetics at defined pressures. It addresses single-layer geosynthetic products, providing precise test procedures to measure thickness under various loads. The standard is essential for consistent identification, quality control, and integration into technical data sheets or complementary property tests, such as hydraulic behavior.

This standard supersedes the 2005 edition, reflecting updated procedures and requirements tailored for a wide range of geosynthetic materials commonly used in civil engineering and geotechnical applications.

Key Topics

• Scope and Purpose
  Applies universally to all single-layer geosynthetics. Specifies thickness measurement methods at specified pressures and load plate areas or point loads.

• Test Procedures
  Four main procedures are detailed:

  • Procedure A: Uses new specimens for each pressure level (2 kPa, 20 kPa, and 200 kPa).
  • Procedure B: Employs incremental loading on the same specimen.
  • Procedure C: Focuses on polymeric and bituminous geosynthetic barriers of uniform thickness.
  • Procedure D: Designed for polymeric and bituminous geosynthetic barriers of non-uniform thickness.

• Apparatus Requirements
  Thickness testers with removable presser-foot surfaces of specified sizes, reference plates, and precise gauges (accuracy to 0.01 mm). The presser-foot ensures uniform pressure across the specimen surface, vital for reliable thickness readings.

• Specimen Preparation
  Minimum of 10 specimens are required, with dimensions exceeding 1.75 times the presser-foot diameter for accuracy. Conditioning for 24 hours is recommended to stabilize test results.

• Measurement and Reporting
  Thickness is recorded as the distance between a reference plate and the presser-foot or between two pressure points for certain barrier materials. Results are expressed as mean values and documented comprehensively, including test parameters and specimen specifics.

Applications

This standard is crucial for industries and engineers involved in the design, testing, and quality assessment of geosynthetics used in:

• Civil Engineering and Geotechnical Projects
  Layers in earthworks, retaining structures, or drainage systems require reliable thickness measurements to ensure mechanical performance and durability.

• Environmental Engineering
  Thickness data informs the behavior of geosynthetics in landfill liners or containment systems, impacting hydraulic resistance and barrier effectiveness.

• Product Development and Quality Control
  Manufacturers utilize this standard to certify product consistency and compliance with contractual specifications.

• Research and Testing Laboratories
  Provides a repeatable, internationally recognized method for thickness evaluation essential for comparative studies and certification processes.

Related Standards

• ISO 9862
  Geosynthetics - Sampling and Preparation of Test Specimens. Compliments EN ISO 9863-1 by ensuring specimen consistency.

• ISO 25619-1
  Geosynthetics - Determination of Compressive Behaviour - Part 1: Compressive Creep Properties. Offers methods related to mechanical behavior under long-term loading, supporting comprehensive geosynthetic characterization.

Summary

EN ISO 9863-1:2016 sets forth a robust framework for measuring the thickness of single-layer geosynthetics under controlled pressures, vital for the material’s identification and performance evaluation. Its procedures ensure repeatability and accuracy, supporting engineers, manufacturers, and testing bodies in delivering reliable data critical for the successful application of geosynthetics in infrastructure, environmental protection, and material innovation.
