12. Different between Zap-Up* & Standard ESD shoe Zap-Up* Standard ESD Shoe More than 100V Less than 50V 4. Body Voltage May/ may not complied to S20.20 Complied to S20.20 electrical hazard limit 6. Safety Often non-permanent with migratory additive Permanent for life 5. ESD Permanency Typically 10e6 to 10e8Ω Better (1MΩ to 2 MΩ) 3. Elec Resistance May/may not meet compliance Meets life-time compliance 2. ANSI/ESD S20.20 More Expensive Cheaper 1. Price
13. ESD Shoe Resistance Test (ANSI/ESD STM 97.1) 1 to 2 MΩ show completely a person’s body-to-ground test
