To guarantee workplace safety with static-dissipative footwear, you'll need to meet 10 key standards: maintain electrical resistance between 0.1-100 megaohms, verify compliance with EN ISO 20345 and ASTM F2413, guarantee discharge times under 0.2 seconds, keep contact resistance below 35 megaohms, conduct regular testing under both wet and dry conditions, follow proper maintenance protocols, maintain controlled temperature during testing, document certification compliance, implement routine inspection programs, and verify industry-specific requirements. Understanding these standards helps protect sensitive equipment and prevent workplace hazards, but there's much more to maintaining a thorough static control program.
Footwear Resistance Testing Requirements
Static-dissipative footwear testing involves rigorous procedures to guarantee workplace safety compliance. You'll need to verify that your footwear meets specific electrical resistance requirements, typically ranging from 10^6 to 10^8 ohms for static dissipative shoes.
These standards differ from antistatic footwear, which allows a broader range from 100 kiloohms to 1 gigaohm, and conductive footwear, which must measure between 0 and 500,000 ohms. CSA certified footwear requires testing in water for 5 seconds.
Testing must occur under both dry and wet conditions to verify the footwear's performance in various environments. You'll need to maintain specific atmospheric conditions during testing, including controlled temperature and humidity levels.
The testing process involves using metal spheres or shot pellets inside the footwear, along with a base electrode plate. You'll apply a specified voltage for a prescribed time while measuring electrical resistance.
To comply with standards like EN ISO 20345 and ASTM F2413, you must conduct regular testing using approved methods. You can use commercial testers that measure resistance between a hand-held metal bar and metal plate, or follow IEC TS 61340-4-3 specifications using shot pellets and a steel plate configuration.
Static Control Performance Measures
You'll need to understand two critical measures for ESD footwear compliance: electrical resistance testing and maximum voltage limits.
Your ESD footwear must maintain a resistance range between 1 x 10^6 and 1 x 10^8 ohms, which you can verify through twice-daily testing procedures. Regular testing is essential since ESD footwear and flooring work together as an integrated static control system.
According to ANSI/ESD S20.20 standards, your ESD footwear and floor combination shouldn't generate more than 100 volts of static electricity.
Electrical Resistance Testing Requirements
Testing requirements for electrical resistance in workplace footwear are governed by precise standards, with BS EN IEC 61340-4-3:2018 setting the benchmark range of 0.1 to 100 MΩ.
Anti-static footwear must maintain electrical resistance levels between 0.1 and 1000 megaohms to meet safety requirements.
You'll need to use commercially available footwear conductivity testers, such as the Sole-Mate TM II, to verify compliance with these requirements.
The IEC TS 60079-32-1 standard outlines how to measure resistance between a hand-held metal bar and a metal plate.
When you're working in environments with electronic components or flammable materials, you must maintain strict adherence to these testing protocols. You can't rely on visual inspection alone, as static dissipative properties can change during use.
Instead, you'll need to conduct regular testing using standardized procedures, which may include the alternative method of filling shoes with shot pellets on a steel plate, as specified in IEC TS 61340-4-3.
For proper compliance, you should establish an in-house testing program using approved footwear testers. This is particularly vital in hazardous environments where static electricity poses significant risks.
Remember that meeting these requirements isn't just about regulatory compliance – it's essential for preventing damage to sensitive equipment and verifying workplace safety.
Maximum Voltage Dissipation Limits
Effective voltage dissipation forms the cornerstone of workplace safety standards for static-dissipative footwear. You'll find strict performance measures that regulate how quickly and effectively your footwear must dissipate static charges, with standards requiring discharge times of less than 0.2 seconds to guarantee maximum protection in sensitive environments. High-quality products like Ergo-Stat grounders achieve spectacular static decay performance.
- SD ranges vary from 10 to 100 megaohms, with specific requirements based on your industry's needs

ESD Protection Rating Systems
You'll find that ESD footwear ratings center on resistance measurements, with standards requiring less than 35 megaohms of contact resistance to meet compliance.
Testing methods involve measuring the resistance between a person's hand on a metal plate and their feet on a conductive electrode, all under controlled temperature and humidity conditions as specified by EN 61340-4-3.
Proper ESD protection requires specific footwear classifications ranging from S1 to S5, with each level offering different protective features while maintaining the necessary static dissipative properties. Regular cleaning and maintenance of footwear is essential since dirty contact areas can significantly reduce static dissipative performance.
Resistance Range Standards
Several key resistance range standards govern the classification and performance of ESD-protective footwear. You'll need to understand that ESD footwear must maintain electrical resistance between 0.1 and 100 MΩ to comply with BS EN IEC 61340-4-3:2018, which is considerably more stringent than anti-static footwear requirements of 0.1 to 1000 MΩ.
Footwear must demonstrate contact resistance below 35 MΩ to qualify as ESD capable. Testing is typically conducted at 25°C ambient temperature to ensure standardized measurement conditions.
Testing must occur under specific temperature and humidity conditions.
Certification requires precise resistance measurements following standard protocols.
When you're selecting ESD footwear for your workplace, you'll find that these resistance ranges aren't arbitrary – they're specifically designed to protect sensitive electronic equipment while maintaining enough conductivity to safely dissipate static charges. The standards guarantee that static electricity flows in a controlled manner through the footwear to the ground.
This is particularly vital in electronics manufacturing and explosive environments where uncontrolled static discharge can damage components or create safety hazards.
You'll need to verify that your ESD footwear supplier provides certification documentation confirming compliance with these resistance standards, as this guarantees reliable protection for your sensitive equipment and processes.
Test Methods Explained
Building on established resistance standards, proper testing methods guarantee ESD footwear performs as intended in the workplace.
You'll need to understand both contact and air-gap discharge tests, which measure your footwear's ability to withstand different types of electrostatic discharge. Contact discharge directly tests the maximum voltage resistance, while air-gap discharge evaluates protection across an air space.
When testing your static-dissipative footwear, you can use devices like the Sole-Mate II to verify its protective condition. According to safety standards, footwear must maintain a resistance range of 1 to 100 megohms for proper static dissipation. For a more detailed evaluation, you'll encounter two primary methods: the hand-held metal bar method and the steel plate method.
The steel plate method, specified by IEC TS 61340-4-3, measures resistance between your shoe (filled with shot pellets) and a metal plate. Meanwhile, the hand-held metal bar method assesses the complete resistance path through your body and feet.
You must verify that your footwear meets IEC 61000-4-2 ratings, which range from Level 1 (2 kV) to Level 4 (8 kV contact/15 kV air). Most ESD protection devices comply with Level 4 or higher, providing you with reliable protection in hazardous workplace environments.
Material Composition Standards
Through rigorous industry standards, static-dissipative footwear must incorporate specific materials that facilitate safe electrical charge dispersion. You'll find that these shoes typically feature conductive rubber or polyurethane outsoles embedded with carbon or metallic particles, creating a reliable path for static discharge.
