# Table 2, Footnote 6 states: “A periodic body voltage generation test should be done to verify the voltage is less than 100 volts.” Does Product Qualification of the Footwear/Flooring System need to be done on a periodical basis?

Yes, if the requirements are met. Per ANSI/ESD S20.20-2021 Section 8.3.1 – “Insulators”:
“For any process essential insulators located **less than or equal to 25 mm from an unprotected ESDS item** , the voltage on the surface of the insulator shall be less than 125 volts when measured with a non-contact electrostatic voltmeter. When using an electrostatic field meter, the reading shall be less than 125 volts when measured at the meter’s stipulated measuring distance.”

This is a recommendation only. While a good idea to do this test on a periodic basis, there are no requirements to perform this test after qualification.
