Qualification Report – ANSI/ESD S20.20 - SCS R3 Dissipative Rubber Mat

Q: What standard and product are qualified in this report?

The report qualifies an SCS R3 dissipative rubber mat under ANSI/ESD S20.20.

Q: How are resistance results measured and under what conditions?

Resistance is measured as resistance to a groundable point and resistance point-to-point after 48–72 hours conditioning at 12% RH and 50% RH (23°C), using 100V and N=3 specimens.

Q: Which test method and references are used for the data tables?

Test methods reference ANSI/ESD STM4.1, and the figures are identified for work-surface measurements: Figure 1 for resistance-to-groundable point and Figure 2 for resistance point-to-point.

Qualification Report – ANSI/ESD S20.20 evaluates a SCS R3 dissipative rubber mat using surface resistance testing under controlled environmental conditions. Measurements are reported as resistance to groundable point and resistance point-to-point, taken after 48–72 hours conditioning at 12% RH and 50% RH (23°C), with N=3 specimens and a 100V test voltage. Data include pass thresholds, per-position sample results, and statistical min/mean/max values. Test methods reference ANSI/ESD STM4.1, with calibration and equipment listed for the corporate lab environment chamber and resistance measurement instruments.
