European standard for raised access flooring
BS EN 12825 has six classifications of ultimate load, ranging from >4kN to >12kN. There is then a choice of a safety factor of 3 or 2. For each of these ultimate load and safety factors, three maximum deflections under working load conditions are available - 2.5mm, 3.0mm and 4mm.
Ultimately the standard creates 72 classes from which to select. The complexities involved in writing a specification can be arduous and there is scope for misinterpretation. Our Technical Specification Team are always available to help advise on selecting a raised access flooring system that is suitable for your building project.
