Comparison table for Defined Movement Specifications.
|UK Concrete Society TR34 4th edition||ACI Fmin numbers||DIN 15185||VDMA|
Although all the above specifications have the same method of testing transverse elevation, DIN 15185 and VDMA do not have a rate in change in elevation control.
TR34 and ACI F min are measured in the same way and have the same properties of measurement. DIN 15185 and VDMA are measured the same both transversely and longitudinally but have different property limits. VDMA also has a micro wave control called Fx.
As there are no direct comparisons longitudinally, comparisons have been made by testing many 1000’s of metres of the same floor but with differing instruments.
