Raised Flooring Grades

The quality and performance characteristics of manufacturer’s products vary considerably. Key performance criteria are stipulated for the component parts of a system and generally Contract Administrators or end users will confirm their performance requirements in-line with one of the following specifications:

• National Building Specification Ltd October 1991 Standard Version K41
• PSA MOB PF2 PS/SPU
• BSEN12825 European standard

BSEN 12825 and PSA/MOB PF2 PS SPU – What are the main differences?

There is no British Standard for raised access floors but the PSA Method of Building performance specification “Platform floors (Raised Access Floors)” MOB PF2 PS is the de facto industry standard. The K41 specification is dominant and refers to the PSA MOB PF2 PS/SPU as a specific reference document used in its drafting. The two documents are therefore intrinsically linked in most specifications.

BS EN 12825 was formally adopted in August 2001 under the European Harmonisation Programme as a means of providing equal opportunities of tendering and trading in the UK for European manufacturers of raised access floor products. At this point we would confirm that contrary to the assertions of certain manufacturers, the PSA MOB PF2 PS/SPU has NOT been superseded by the European BSEN12825 specification; it is simply another specification route albeit subject to less stringent rules.

Systems which are compliant with PSA MOB PF2 PS/SPU are subject to independent testing criteria and performance standards. In general these standards are far more stringent than those governing the new European standard BSEN12825. Floors installed to PSA MOB PF2 PS/SPU have a 3 times safety factor whilst those installed to BS EN 12825 have only 2.
