ESD Sandals | Electric Static Dissipative footwear

B.A.S.S. (Belgium's-A-StaticScience) * ESD prevention clearly distinguish the difference between an ESD work shoe and an ESD Safety Shoe.  ESD shoes,to whom belong ESD sandals, have an electrostatically dissipative conductive shoe sole, popularly known as antistatic shoes (which is not the same, incorrectly).  Safety Shoes are classed as ESD safe shoes when the resistance value of the system person-shoe-floor is below 3,5 x 10^7 resp. 35 MOhm according to EN 61340-5-1.

IEC 61340-4-3, Electrostatics Part 4-3: Standard test methods for specific applications : Footwear

IEC 61340-4-5, Electrostatics Part 4-5: Standard test methods for specific applications : Methods for characterizing the electrostatic protection of footwear and flooring in combination with a person.

5.3.2 Personnel grounding

For standing operations, personnel can be grounded via a wrist strap system or by a flooringfootwear system. When a flooring-footwear system is used, either of the two following conditions shall be met:

  • the total resistance of the system (from the person, through the footwear and flooring to equipment ground) shall be less than 3,5 × 107 ?;
  • the maximum body voltage generation shall be less than 100 V and the total resistance of the system shall be less than 1 x109 ?.

A.2 Measurement procedure for ESD-footwear testing 

The operator shall stand with one foot on the conductive footwear electrode. The hand contact plate shall be pressed to verify that the person/footwear system resistance is within acceptable parameters (see Figure A.2). The test shall be repeated for the other foot. The test apparatus can be an integrated, commercially available tester or other instrumentation that is capable of measuring resistance from 5,0x104 Ω to at least 1,0x108 Ω. The tester open-circuit voltage is typically between 9 V d.c.and 100 V d.c.
