The higher the compactness, the lower the water absorption and the greater the value required to break the tile. It is important to underline that the breaking load of a single tile, measured according to the en ISo 10545/4 standard is generally much lower than the real load capacity of that same tile once installed on the loor. It can be shown, by means of calculations and mathematical models, that the load capacity of a itted tile is superior even by a few dozen times, to the load that causes the rupture, during the bending resistance test in the laboratory, of the single tile when it is not installed.
È importante sottolineare che il carico di rottura della singola piastrella, misurato secondo la norma en ISo 10545/4 è generalmente assai inferiore alla reale capacità di carico della stessa piastrella in esercizio, una volta inserita nel pavimento.
