Is Carpet More Conductive Than Tile

Conductive carpet tile is often specified incorrectly for use around energized equipment in call centers 911 dispatch areas flight towers and server rooms.

Is carpet more conductive than tile.

1e06 ω or 1 meg ω to 1e09 ω. The conductive adhesive must always be more conductive than the surface of the floor. If point to point resistance is lower than the point to ground resistance which again would happen if the adhesive were not as conductive as the tile there may be cause for safety concerns. Faa 019f section 4 1 3 3 2 for instance contains a safety warning saying conductive materials shall not be used for floor mats carpeting or other flooring where personnel may be in.

The adhesive did not in any way alter the resistance or conductivity of the flooring material. If the flooring material is more conductive than the underlying adhesive electrostatic esd charges will remain on the floor surface potentially creating a safety hazard for people walking on. Due to its material composition conductive rubber restricts and controls the flow of electricity more predictably than composite floors like conductive carpet tile. To confirm that a flooring material meets electrical specs for the specific application test surface.

United s esd carpet tiles broadloom is true esd conductive carpeting not mere off the shelf carpeting sometimes marked as anti static. 2 our conductive precoat binds the yarn tufts to the primary backing and provides electrical continuity across all tufts. Conductive tile is required in these areas. Items dropped on tile floors are more likely to break when compared with items dropped on carpeted floors.

If the floor is more conductive than the underlying adhesive charges may remain on the surface of the floor creating a potential safety hazard. Some conductive carpet products measure as low as 2 5 x 10e4 25 thousand ohms or lower 40 times more conductive than recommended safety standards. This conductive coating draws static charges downward from the walking surface through the thickness of the tile. Explosives handling is a special case.

Static conductive true esd carpeting provides reduced maintenance cost finally no more esd floor waxes or strippers as well as ergonomic comfort and outstanding sound deadening capabilities. Static dissipative tile measuring less than 1 0 x 10 e8 should be used in these applications. Tile and carpet disadvantages. Tile is a more permanent option than carpeting and it is.

As we know electricity always seeks its fastest path to ground. The underside of the shadowfx carpet tile backing is pre coated with a conductive carbon loaded material. I would consider sd material to be the minimum requirement per ansi esd s7 1 2005 via ansi esd s20 20 2007.
