Full title and description

St ISO 25619-2-2015 — Geosynthetics — Determination of compression behaviour — Part 2: Determination of short-term compression behaviour. This International Standard specifies an index test method to determine the short-term compressive deformation behaviour of geosynthetics under a short-term compressive stress, and is intended primarily for quality control rather than for design.

Abstract

ISO 25619-2:2015 defines a laboratory index test for measuring the short-term compression behaviour of geosynthetic products. The method quantifies deformation under short-term compressive loads and can be applied to specimens after exposure to compressive stress, liquids or light. Results are intended for comparative and quality-control purposes and are not intended to be used directly for structural design.

Scope

This part of ISO 25619 specifies an index test method for determining the short-term compressive behaviour of geosynthetic products. It covers specimen preparation, test apparatus, loading procedure and measurement of deformation under short-duration compressive stress. The procedure is intended for laboratory comparative testing and quality control and is not intended as a basis for design calculations.

Key topics and requirements

• Purpose: index test for short-term compressive deformation of geosynthetics.
• Specimen preparation: defined specimen size and conditioning; provisions for pre-exposure to liquids, stress or light where relevant.
• Test apparatus: description of platens, loading device and displacement-measurement instruments suitable for short-term compression testing.
• Loading procedure: application of a specified compressive stress for a defined short test duration, with controlled loading rate where applicable.
• Measurement and reporting: record deformation (compressive strain) versus applied stress and report test conditions, specimen details and any preconditioning.
• Limitations: method is an index test for quality control and comparison — not intended for direct use in design or long-term performance prediction.
• Environmental considerations: guidance for tests after exposure to liquids or light; tests may be run dry or after specified conditioning.

Typical use and users

Used by materials and quality laboratories, geosynthetic manufacturers, third‑party test houses and specification authors for acceptance testing and product comparison. Geotechnical consultants and procurement teams use results to verify batch consistency and manufacturing quality, while design engineers consult the standard to understand product test data — but do not use it alone for structural design.

FAQ

Q: What is this standard?

A: ISO 25619-2:2015 is an International Standard that specifies an index laboratory test method for determining the short-term compressive behaviour of geosynthetic products.

Q: What does it cover?

A: It covers specimen preparation, required test apparatus, the procedure for applying short-term compressive stress, measurement of deformation and the format for reporting results. The focus is comparative testing and quality control, not design.

Q: Who typically uses it?

A: Manufacturers, independent testing laboratories, quality assurance/quality control personnel, procurement teams and geotechnical consultants who need standardized short-term compression data for geosynthetic materials.

Q: Is it current or superseded?

A: ISO 25619-2:2015 (Edition 2) is the current published edition; the 2008 edition was withdrawn and replaced by the 2015 edition. The 2015 edition was confirmed on review in 2021 and remains current.

Q: Is it part of a series?

A: Yes. ISO 25619 is a multi‑part series addressing compression behaviour of geosynthetics. Part 1 covers compressive creep properties (latest revision published 2021) and Part 2 covers short-term compression (this document).

Q: What are the key keywords?

A: Geosynthetics; compression behaviour; short-term compression; index test; quality control; geotextiles; compressive deformation; ISO 25619.
