Notes:
The above comparisons are not direct numerical comparisons but based on the results of over 1 million square metres of floor survey results. A direct comparison is not possible due to the above specifications having completely different methods of data collection and data analysis.

Defined Movement Specifications
| DEFINED MOVEMENT SPECIFICATIONS | | ACI FMIN NUMBERS | TR34 TABLE 4.3 | TR34 APPENDIX C
TABLE C.1 | DIN 15185 | | Fmin 100 | Superflat | DM1 | Comparable | | Fmin 75 | Category 1 | DM2 | | Fmin 50 | Category 2 | DM3 | - |
Notes:
Although the above specifications have very similar compliance tests for the transverse property, they all have very different methods of measuring the longitudinal property's, save Fmin and TR34 DM categories which are comparable. The comparisons have therefore been made, mainly on the transverse property's and many 1000's linear meter of aisle checked with multiple comparative surveys.
