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 movement within modular carpet tile products when exposed to controlled heat and moisture cycling. The test is historically associated with carpet tile evaluation methods referenced by the U.S. General Services Administration (GSA) and is commonly used to assess backing-system stability under environmental stress conditions. Aachen testing may assist in evaluating claims involving tile growth, shrinkage, seam peaking, gapping, doming, edge deformation, or modular misalignment. The procedure evaluates dimensional movement characteristics only and does not independently determine installation quality, adhesive performance, appearance retention, maintenance conditions, or overall field serviceability. See also Carpet Seam Peaking, Carpet Problems, and Flooring Laboratory Testing and Analysis for broader context.
