Hi John,
Do electric torque driver required product qualification? If yes, which standard shall be use a reference. If no, what is justification. The Electric driver is grounded.
Thanks

There are no qualificaiton requirements for hand tools at this time. I would treat this as a possible isolated conductor. If the tip to ground is less than 10*9 ohms, then it is not isolated.
Second, does it come into contact with an ESD sensitive item? Typically these types of tools only connect the “ground” cponnection of a device which is typically not that sensitive.
In any case, if it is grounded it should be fine.

Thanks John for your technical feedback.

Hello,
Greetings of the day to all from India
As of now, neither of the two standards have any specific Information defined on the evaluation of hand tools like Brushes-Tweezers- Pliers etc, except the one on Soldering /Desoldering per ANSI/ESD S.20.20.2021
The main idea is to measure the resistance of the person holding the tool to ground. Generally, a loop resistance measurement from the hand, through the tool, to a metal plate. This technique can be applied to brushes, tweezers, and most hand tools. Some tools can be measured for electrical resistance using a two-point probe or static decay using a charged plate monitor.

Good day
