Desco 66045 Blue Rubber Statfree T2 Mat Premium Dissipative Dual Layer, 48" Length x 24" Width x 0.06" Thick
Dissipative dual layer rubber material provides a worksurface that does not generate a static charge and will control the discharge rate from all conductors (including esd susceptible items) that are placed on the surface. Meets ANSI/ESD S20.20 worksurface required limit and recommendation of ANSI/ESD S4.1 for contact with ESD susceptible items. Electricals will not drift for the life of the mat. Conductive (less than 10^4 Rtt) bottom layer - limited lifetime warranty: The dedicated conductive layer reduces the resistance to ground (Rtg) from the top of the surface to the groundable point ground and allows the mats to be used with ESD workstation monitors. Electricals will not drift for the life of the mat. Includes 14213 Ground Cord. Lead-free RoHS compliant. Made in America. "The most important functional consideration for worksurfaces is the RTG resistance from the top of the surface to the groundable point." ANSI/ESD S20.20 Table 1 recommends a requirement of less than 1 x 10E9 ohms. "If Charged Device Model damage is a concern then setting a lower resistance limit should be considered. Typically, 1 x 10E6 ohms." "Durability factors that should be considered are hardness, abrasion resistance, tear resistance, etc. Worksurfaces may require special heat resistant materials. Light reflection may be an important ergonomic consideration." (Ref: TR 20.20 section 5.3.1).
