UNE 103-602 covers determination of swelling pressure in soils using an oedometer or consolidometer-style laboratory setup.
For geotechnical laboratories, this reference usually points to consolidation cells, controlled loading, displacement measurement, specimen preparation, and careful reporting of swelling behavior. If you need help matching the cited requirement to a practical equipment path, contact our team.
UNE 103-602 Determination of Swelling Pressure of a Soil in an Oedometer
UNE 103-602 is a Spanish geotechnical test standard for determining soil swelling pressure. It is relevant when expansive soils or moisture-sensitive geotechnical materials are part of the project evaluation.
The standard should be followed with the exact edition named by the project requirement because specimen handling, loading, and interpretation details can affect the result.
Quick Definition
Document type: geotechnical test standard.
Main focus: swelling pressure of soil measured in an oedometer-style apparatus.
Primary equipment path: oedometers, consolidation cells, loading systems, displacement measurement, and specimen preparation tools.
What This Standard Covers
UNE 103-602 covers laboratory determination of the pressure associated with soil swelling under controlled conditions.
The method is especially relevant for soils that may expand with moisture change and where swelling pressure can affect foundations, pavements, slabs, retaining structures, or earthworks.
Why This Standard Matters in Testing
Swelling pressure is important because expansive soils can create uplift, distortion, cracking, or long-term serviceability problems.
For labs and buyers, the cited standard helps define the equipment path needed to apply controlled conditions and capture reliable deformation or pressure response.
Common Materials, Product Types, or Applications Covered
The standard applies to soil specimens prepared for geotechnical swelling pressure evaluation.
Common material or product areas: expansive soils, clay-rich soils, compacted soil specimens, undisturbed samples, and project-specific geotechnical materials.
Common application questions: whether a soil specimen can generate swelling pressure that matters for geotechnical design, construction control, or failure investigation.
Common Test or Verification Workflow
A typical workflow places a prepared soil specimen in an oedometer or consolidation cell, controls moisture and loading conditions as required, and records the response needed to determine swelling pressure.
The specimen condition, loading path, drainage condition, and acceptance interpretation should follow the cited UNE requirement.
Workflow focus: specimen preparation, oedometer setup, controlled loading or restraint, swelling response measurement, and reporting.
Equipment Commonly Used for This Standard
UNE 103-602 generally uses geotechnical consolidation or swelling-pressure equipment rather than general-purpose tensile equipment.
Common equipment families: oedometers, consolidometers, swelling pressure cells, loading systems, displacement sensors, specimen rings, trimming tools, water-control accessories, and reporting software.
Selection focus: confirm specimen size, pressure range, measurement resolution, number of cells, loading method, and exact edition before quoting equipment. If you are comparing equipment configurations for this workflow, request a quote.
How to Read This Designation or Revision
UNE 103-602 is a UNE designation for a Spanish geotechnical standard.
The cited year or current project specification should control the setup because geotechnical standards may be replaced, adopted, or referenced differently across contracts.
Related Standards, Methods, or Frameworks
UNE 103-405 and EN ISO 17892-5 can appear in related consolidation or compressibility testing programs, but swelling pressure should be handled according to the exact cited requirement.
