- The step sound reduction depends on the floor construction (thickness of the floating floor, cement, etc.). The step sound reduction is assumed with a standard mock-up, and a full EN 10140-3 test is initiated.
- The material test is made in accordance with EN 17409:2019 and the result is presented as an average of the latest analysis of the rubber.
- Non-standardised test method for the determination of density and the detection of free impurities in rubber granules. The test method is used as the values obtained using ASTM D5603 are below the detection limits.
