In our daily life, so much friction is occurred frequently at the office especially. Walking or moving with chairs on floor often result in friction. Static electricity occurred by friction at this time is stored in the human body and make people feel unpleasant. MAXI F&R TILE with antistaitc finishing material decreases static electricily for certain amount of time or prevents people from feeling static electricity.  The method of test The outline of test The method of test JIS L 1023-1992 Complying with stroll method. Measure electrification potential when pedestrian keeping a lead line walks regulary(100 step/Min.) on the floor laid raised floor.(shoes : Synthetic shoes) Electric resistance of MAXI F&R TILE is the level of 108Ω. In case of raised floor base of metal, human body electrification potential and time to be cut in half in human body electrification potential is so small. Moreover, Antistatic quality is excellent human body electrification potential and Time to be cut in half in human body electrification potential could be changed much by a kind of raised floor base and shoes.  The method of test The outline of test The method of test JIS K 6911 Measure surface resistance and volume resistance on floor itself. Measure electric resistance of floor, using electrode like a picture.
