Schluter®-DITRA-HEATTesting and CertificationsUncoupling MembraneThe method used to establish the overall performance of a tile assembly under loading is the ASTM C627 “Standard Test Method for EvaluatingCeramic Floor Tile Installation Systems Using the Robinson Type Floor Tester.” The assembly is tested in cycles using a loaded, revolvingcarriage. Load, wheel hardness, and number of revolutions vary with each cycle. Once a specified level of damage is exceeded, the test isstopped. The TCNA Handbook for Ceramic, Glass, and Stone Tile Installation assigns performance levels to an assembly based on the numberof cycles successfully completed. The ratings include residential, light, moderate, heavy, and extra heavy, in order of improving performance.
