Deflections:

The following is designed to help when calculating an acceptable deflection rate: For pedestrian traffic, the deflection of a floor panel under the design load shall not exceed 10mm or 1/200th of the span, whichever is the lesser. The difference in level between a loaded and a neighbouring unloaded flooring shall not exceed 4mm.

Deflections rates taken from BS4592-0:2006.

Below load data is for a concentrated load, a point load of approx. 300x300mm square similar to pedestrian loadings.
