Weight rating of cushion estimated based on load at which the performance test chosen no longer functions at design specification.

Weight Rating by Performance

Why this test is needed

The weight rating of a surface identifies the size of a patient that should use that product. An incompatible fit of patient to support surface could result in tissue damage.

How this test is performed

The support surface is aged with desired safety factor and is tested to identify when it stops performing its design specification.
