Hi experts,
Do I need to measure Voltage in a ESD worksurface - besides resistance based on TR53? (What would be the limit if I want to keep this Voltage measurement?)
Thank you
Santiago,
You do not need to measure the voltage of a worksurface because if your worksurface meets the ANSI/ESD S20.20 resistance to ground compliance verification limit of < 10^9 ohms, it should not be able to hold a voltage. If your worksurface is holding a voltage, it would be either an insulator or an isolated conductor with a resistance to ground > 10^9 ohms.

Hello,
Greetings of the day from India
TR 53 is for compliance verification test audits and it calls for testing of Rg only per ANSI /ESD STM4.1
For Product qualification test per S 20 20 -2014 it was required to measure the surface voltage also per ANSI/ESD STM 4.2 but it is withdrawn in the current 2021 version and ANSI/ESD STM 4.2 is no longer valid.
Now, only per ANSI /ESD STM4.1 Rgp (resistance to ground able point) for PQ test and Rg (resistance to ground) for CV test are required.
Thank you
