ESD Infomation:
	
All parts of the chair are anti static
	
The chair is either covered in “Hi Tech” Fabric or Medistat vinyl which are both dissipative materials and have a resistance to ground point
	
That does not exceed 10’10
	
The seat and backrest is earthed to the chassis mechanism.
	
The chassis is connected to the chromed gas lift, this fits into the polished alloy base and all is grounded via the conductive castors or glides, whichever is fitted.
	
The chairs are checked using a OHM – STAT MEGOHMMETER.
	
The test is carried out by placing a 5 kilo weight on the chair seat. This weight is connected to the test box and another lead from the test box is connected to a steel plate placed under one of the castors ( or glide) . A charge is then passed through the chair to determine resistance to ground.
