ESD Brush made in Electrostatic Discharge (ESD) protective materials protect contents from static electricity and electrostatic damage.These materials are designed to absorb the charge and pass it to the ground , saving you thousands of dollars by reducing or eliminating product damage. It conforms to ANSI/ESD S20.20*1999 requirement.This standard requires conductive materials surface resistance to be <1.0 x 10^4 ohms and dissipative  materials to be >1.0 x 104 ohms to <1.0 x 10^9 ohms when tested per  EOS/ESD S11.11. The materials also conform to the static decay requirement of FTM-101B, Method 4046.1 dissipating a 5000 Volt charge to 0 when grounded in less than 2 seconds.
