ASTM D8203-18 (2023) PDF

Full title and description

Standard Test Method for Determination of the Horizontal Water Flow Rate of a Geosynthetic Screening Material, Product, or Device — ASTM D8203-18 (reapproved 2023). The method defines a laboratory procedure to measure the horizontal water flow rate through geosynthetic screening materials and sediment retention devices (SRDs) under a constant-head condition using potable water; it is intended primarily for quality control and product development rather than as a performance specification.

Abstract

ASTM D8203 specifies placing a test specimen across the mouth of a box reservoir and maintaining a predetermined constant head upstream; once steady-state seepage is reached the discharge volume and elapsed time are measured to calculate horizontal water flow rate. The test simulates clear-water sheet-flow conditions (no sediment) and yields an index property useful for comparing and controlling SRD products.

Scope

This test method covers procedures for determining the horizontal water flow rate through a geosynthetic or geosynthetic‑enhanced screening device (for example, silt fences, wattles, filter logs, and similar SRDs) under a constant-head pressure using potable water. The standard is intended for use in quality control and product development and expressly is not a full performance test for site conditions. SI units are the standard for the method.

Key topics and requirements

• Test specimen installation across an upper “box” reservoir and sealing against the box bottom and sides to prevent bypass flow.
• Use of a lower receiving reservoir sized to accommodate seepage and permit steady-state measurements.
• Maintaining a predetermined constant upstream head and measuring discharge volume and elapsed time after steady-state is achieved.
• Reporting horizontal flow rate as an inherent (index) property for comparison, quality control, and assessment of product changes (not a field performance guarantee).
• Referenced terminology and related practices (for example, Terminology D4439 and Practice D4354) are used to define terms and sampling procedures.

Typical use and users

Used by manufacturers of geosynthetic screening products and sediment retention devices, independent testing laboratories, environmental and civil engineers involved in erosion and sediment control, research institutions studying SRD behavior, and quality‑assurance teams evaluating product changes. Accredited geosynthetics laboratories and industry accreditation bodies commonly list D8203 among test methods for SRD characterization.

Related standards

Commonly referenced documents include ASTM Practice D4354 (sampling of geosynthetics), Terminology D4439 (geosynthetics terminology), Guide D5819 (selecting test methods for geosynthetic evaluation), and other D35 committee publications covering erosion-control products and SRDs. The test is under the jurisdiction of ASTM Committee D35 on Geosynthetics (Subcommittee D35.05).
