Scope
This part of GB/T 35426 specifies the method for determining the dynamic stiffness of elastic materials used under ordinary floating floors. Dynamic stiffness is one of the parameters that determine the sound insulation performance of floating floors.
This part is applicable to the determination of the dynamic stiffness per unit area of elastic materials that are surface-smooth (see 6) and used continuously under floating floors; it is not applicable to the determination of the dynamic stiffness of elastic materials with a load less than 0.4 kPa1) (such as wall lining materials) or a load greater than 4 kPa1) (such as materials under machine bases).
