Is the performance of your dycem floor covering still high enough?
[18.09.2006]Has it been two years or longer since you installed a Clean Zone or Work Zone floor covering from Dycem? Then it is high time to check whether the floor covering is still functioning properly – namely preventing contamination in the cleanroom.
You purchased a CleanZone or WorkZone because 99% of detectable contamination in the cleanroom can be prevented by the use of these floor coverings.
This assumes, of course, that the floor covering was installed professionally and was cleaned at regular intervals using adequate cleaning agents. However, even when treated according to instructions, the particle retention capacity of the floor covering decreases over time. A test method developed by Dycem reveals this phenomenon.
A special measuring instrument – the Advanced Force Gorge (AFG) – was developed for the easy and highly specific measurement of tension and compression forces in Newtons.
The measured Newtonian force is set in relation to the particle retention capacity and the particle collection capacity of CleanZone and WorkZone, as illustrated in the table below. The higher the force in Newtons, the higher the particle retention capacity of the floor covering. The table contains typical readings for CleanZone measured with an AFG in relation to the percentage of particles removed from a clean surface.
If the attraction force in Newtons is less than 10, then we recommend replacing the floor covering, since this corresponds to a maximum particle retention capacity of only 55%.
Undoubtedly, you too would like to ascertain whether the floor covering installed two or more years ago still fulfils its purpose: to prevent particles from penetrating the cleanroom.
Therefore: take no risks and make an appointment with us to measure the function of your floor coverings!
Note: This measuring method was designed and tested only for CleanZone and WorkZone. The suitability of this technique can therefore not be guaranteed for peel-off mats or other polymer floor coverings.
