“The most important functional consideration for work surfaces is the resistance from the top of the surface to the groundable point (Rgp).
This establishes the resistance of the primary path to ground for items placed on the surface. IEC 61340-5-1 has set a resistance to ground
range for work surfaces of less than 1,0 x 10E9 ohms. However, it is sometimes necessary to use work surfaces that are much more
conductive. This is allowed under IEC 61340-5-1 but the reasons for using a more conductive work surface shall be documented in the ESD
control program plan.” (CLC/TR 61340-5-2:2008 User guide clause 4.7.1.2.5 Electrical considerations – Work Surfaces)
