| Concentrated loads are applied on a small area and are typically imposed by stationary furniture and equipment with legs. A concentrated load is applied to the surface of the panel resulting in deflection and permanent set. Deflection and permanent set (rebound) are measured at the top surface after the load is removed. |
|
Uniform loads are applied over the entire area of the panel and are typically imposed by stationary furniture and equipment without legs. The uniform load rating is specified in kilogram per square meter. |

| The load at which the panel has structurally failed and can no longer accept any loading. This is sometimes expressed as a multiple of concentrated load and referred to as a safety factor. |
|
Dynamic loads are an important factor when selecting the access floor system. Determine the loads and the distribution of the loads which will be rolled across the floor and select the appropriate system. |
