Geosynthetics - Test methods for measuring mass per unit area of clay geosynthetic barriers

This European Standard describes a test method for the laboratory determination of the mass per unit area of a sample of clay geosynthetic barrier (GBR-C) in the condition as received.
Since manufacturers quote mass per unit area at a given moisture content, it is necessary to measure the moisture content.

Overview

EN 14196:2016 is a European Standard developed by CEN that specifies the test methods for determining the mass per unit area of clay geosynthetic barriers (GBR-C). This standard focuses on laboratory procedures for accurately measuring the mass per unit area of GBR-C materials as received, including the precise evaluation of moisture content in the clay component. The standard provides a systematic approach to ensure reliable and repeatable measurements essential for quality control and product specification in geotechnical applications.

Key Topics

• Scope and Purpose
  The standard applies to clay geosynthetic barriers used primarily in environmental and civil engineering projects. It addresses the importance of measuring the mass per unit area at a defined moisture content because manufacturers typically quote this parameter under specific moisture conditions.

• Test Specimen Preparation
  Specimens must be cut from the geosynthetic barrier in specific sizes and distributed over the full sample width to obtain representative results. The cutting process includes techniques to minimize clay loss, which can impact accuracy.

• Measurement Procedures
  Key equipment includes precise balances, dies or templates for specimen cutting, and auxiliary tools like knives and spatulas. The clay component's moisture content is measured gravimetrically following ISO 11465 standards to ensure consistency.

• Calculation Methods
  The standard outlines formulas to calculate:

  • Mass per unit area of the whole GBR-C specimen
  • Mass per unit area of the clay component by subtracting the synthetic component
  • Moisture-normalized mass per unit area of the clay component adjusted to 0% moisture content

• Determination of Synthetic Component Mass
  If unknown or uncertain, Annex A describes a detailed method to separate and measure the synthetic components’ mass after removing the clay. This includes washing, drying, and weighing procedures to accurately assess synthetic material contribution.

• Reporting Requirements
  Comprehensive reporting guidelines ensure all critical parameters are documented, including sample identification, cutting method, specimen details, constituent descriptions, test values, and any testing deviations.

Applications

EN 14196:2016 is essential for stakeholders involved in the manufacturing, testing, and application of clay geosynthetic barriers in the following areas:

• Environmental Protection
  Used in landfill liners and containment systems where clay barriers prevent contaminant migration.

• Civil Engineering
  Applied in dams, reservoirs, canals, and other water containment structures to ensure water-tightness.

• Infrastructure Projects
  Helps designers and contractors verify material specifications to meet performance and regulatory requirements in roadway embankments and mining operations.

• Quality Control & Compliance
  Ensures consistent product quality across batches and supports adherence to European regulations and project specifications.

Related Standards

To effectively apply EN 14196:2016, users should be familiar with these referenced standards which support the test methodology and terminology:

• EN ISO 9862 – Geosynthetics: Sampling and Preparation of Test Specimens
  Provides guidance on representative sampling techniques crucial for reproducible test results.

• EN ISO 10318-1 – Geosynthetics Part 1: Terms and Definitions
  Defines essential terminologies related to geosynthetic materials for consistent communication.

• ISO 11465 – Soil Quality: Determination of Dry Matter and Water Content on a Mass Basis (Gravimetric Method)
  Specifies the moisture content measurement technique indispensable for normalizing mass values.
