Aachen Dimensional Stability Test (Carpet Tile)

Floor Detective® Laboratory Testing Reference

Summary

The Aachen Dimensional Stability Test is a laboratory procedure used to evaluate dimensional change in modular carpet tile products when exposed to controlled heat and moisture cycling. The test is historically associated with evaluation protocols referenced by the U.S. General Services Administration (GSA) and is intended to assess the dimensional stability of carpet tile backing systems under environmental stress conditions. Results may assist in evaluating claims involving tile growth, shrinkage, peaking, gapping, doming, or modular misalignment. The test evaluates dimensional movement only and does not independently evaluate appearance retention, installation workmanship, adhesive performance, or overall field serviceability. Proper interpretation requires correlation of laboratory findings with field conditions, installation methods, moisture exposure, and environmental history.
