For perfect continuity,ESD chairs must have chrome plated back bars and gas lift tubes, plus special conductive oil in the lift tubes. Check ESD chairs with a surface resistance meter that applies 100 volts. This will only measure the dissipative range of the fabric. Now measure from any point on the fabric on either cushion to the drag chain or ESD caster. It’s easy if you have some thin metal. Just put it under a caster or the chain.

ANSI/BIFMA requires a rating of ten to the ninth or lower, but not lower than ten to the fifth.

The sash chain grounding system should be cleaned regularly. Double chairs have been found to be more reliable.
It's best to investigate the seat and back filtration systems. (The resilient foam padding will begin to break down into fine dust after extended use). Staples should be no farther than 1/4” apart, and silicon should be used for proper sealing around the edges. BenchPro™ recommends inspecting and possibly replacing clean room chairs after 10 years use.
