They can be. It depends upon what your requirements for conductivity with the floor are.
You can also use plain old bare concrete floors without any coverage. They have been known to be sufficient for some conductive requirements. Concrete flooring can be sufficient for such things as storage or not-so-strict assembly areas. But, concrete can be dependent upon the water table and/or moisture content of the ground it's on. Or, the floor can be painted with conductive paint. A paint specifically made for floors. But you may have to monitor the floor more often. Paint has a tendency to chip. Or you can have the tiled flooring bonded to building earth ground with copper strips. Or, you may not have to have the tiles connected with copper strips. Best to have a defined goal of conductivity that you're going to need, then work from there. If you need clean room or telco/Bellcore or medical equipment mfr type grounding, you might consider using the tiles because their conductivity is repeatable and reliable no matter what. - Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
