DYNAMIC STIFFNESS

 

The resilient underlay by Eterno Ivica has the proper elasticity for a high acoustic comfort.

The test is specific for resilient underlays and is performed on a sample of size 200x200 mm. 

The dynamic stiffness test measures the elasticity of a metrial resilient subjected to the load transmitted by the screed above.

The standard that describes the evaluation tests is: UNI EN ISO 29052-1

 

The section below illustrates the position of the resilient underlay in composing a slab. 

It is valid for all the tests shown on the folllowing pages.
