  1. Product qualification is normally conducted during the initial selection of ESD control products and materials. Any of the following methods can be used: product specification review, independent laboratory evaluation or internal laboratory evaluation.
  2. For ESD control footwear/flooring systems that were installed before the adoption of this standard, ongoing compliance verification records can be used as evidence of product qualification.
  3. The required limit of < 1.0 x 10E9 ohms is the “maximum” allowed value. The user should document the resistance values that were measured for product qualification for the footwear and the floor to comply with the < 100 volts body voltage generation and use these resistances for compliance verification.

  2. For standards that have multiple resistance test methods, these limits apply to all methods.
  3. Worksurfaces are defined as any surface on which an unprotected ESDS item is placed.
  4. Due to a wide variety of applications for worksurfaces, specific requirements that could be broadly applied are difficult to determine. If there is a concern for CDM failures, then a lower limit of 1×106 ohms for point to point and point to groundable point should be considered.

AmeriWorx Conductive Vinyl Tile Meets These Requirements

The following test reports show that AmeriWorx Tile meets all aspects of ESDA 20.20-2014 as reflected in the tables below:

EPA = ESD protected area. A defined location with the necessary materials, tools, and equipment capable of controlling static electricity to a level that minimizes damage to ESD susceptible items.

Examples: 100 = 10E2 , 1000 = 10E3 , 10000 = 10E4 , 100000 = 10E5 , 3.49 x 10E4 = 34900
