ASTM D4595/D4595M Standard Test Method for Tensile Properties of Geotextiles by the Wide-Width Method

At a Glance

Document type: Test Method.

Edition: active, current edition D4595/D4595M-23.

Property determined: tensile properties.

Scope

Measurement of tensile properties of geotextiles using a wide-width specimen.

Applicable to woven fabrics, nonwoven fabrics, layered fabrics, knit fabrics and felts used in geotextile applications.

The distinguishing feature is that the specimen width is greater than its length, which minimizes the necking-down effect and gives a closer relationship to expected field behaviour.

Results provide design parameters for reinforcement applications such as reinforced roadways, embankments over soft subgrades, retaining walls and slopes.

What the Result Tells You

A test to ASTM D4595/D4595M characterises the tensile properties of the material or assembly under the conditions the method fixes: specimen form, rate of loading and the environment in which the test is run.

Because the numbers depend on those fixed conditions, a result is only meaningful when the report names the standard, the edition and any options the method allows.

Reading the Designation

ASTM D4595/D4595M: a dual designation. One half carries the inch-pound version and the other the SI version. The two systems are used independently, never mixed inside a single report.

When a drawing, purchase order or quality procedure cites this document, the test setup, the specimen and the report follow that citation.

Below you can find the products in our catalog that support this standard and the related testing workflow.

Side-Action Tensile Grips

Side action tensile grips provide quick, secure clamping for films, thin sheets, textiles, fine wires, polymer strips, and other flexible specimens on universal testing machines. Available in manual lever and screw-action configurations, they support different force ranges, jaw surfaces, and specimen sizes. Their side-clamping design helps improve alignment, reduce slippage, and speed up routine tensile testing in QC and R&D labs.

Snubbing Grips for Wire and Cable Testing

Snubbing grips, also known as capstan grips, are designed for tensile testing of wires, cables, ropes, textile strips, and geogrids that can slip or break in standard clamps. By wrapping the specimen around curved surfaces, they increase friction and reduce grip-end failures. These fixtures help laboratories achieve safer, more repeatable axial loading for high-strength or flexible materials.
