The resilient undelray by Eterno Ivica is resitant at high loads.
The test is specific for resilient underlays and is performed on a sample of size 200x200 mm.
The compressibility test measures the crushing of a resilient material subjected to a load cycle in pre-set time intervals.
The standard that describes the evaluation tests is: UNI EN 12431
Below, an example of a schematization of the loading and unloading cycle with identification of measured thickness.
