Results: Surface Resistivity: 10⁵ – 10⁸ Ω (within dissipative range). Note: Variability is caused by limited contact area, tool movement, and non-flat surfaces (e.g., alligator clips do not provide stable fastening). 2. Handle-to-Tip: Method: While the 2-Point Probe test evaluates the coating’s resistance at localized areas, the handle-to-bit test evaluates the complete resistance path. This approach simulates the actual discharge path during use—when an operator grips the tool and contacts a fastener— verifying continuous static dissipation from the user’s hand to the workpiece. Conductive bits and grounded ESD gloves (<1×10⁷ Ω) were used to simulate operator handling in an EPA environment. RMV Results: Resistance: 10⁷–10⁸ Ω, well below compliance limits.
Interpretation: Demonstrates continuous conductivity from operator grip to fastener, confirming effective static dissipation under use conditions. 3. Electrostatic Decay (MIL-STD-3010C, Method 4046): Method: Electrostatic decay testing measures a tool’s ability to dissipate charge efficiently. Tools are charged to ±1 kV and monitored for decay to ±1.0 volt when placed in contact with a grounded plate. Compliance requires dissipation within 2 seconds to prove the product will not retain a charge that could transfer to sensitive devices. RMV Results: • +1kV to +1.0V: 0.004 second average • -1kV to -1.0V: 0.003 second average Interpretation: Fast decay times demonstrate effective charge dissipation, ensuring minimal ESD risk.
