Safety Shoe Voltage Tester: Essential Guide for Electrical Hazard Compliance

A safety shoe voltage tester is a critical device used to evaluate the electrical insulation performance of protective footwear, ensuring compliance with international safety standards. This equipment applies high voltage to simulate hazardous electric environments, verifying that shoes prevent electric current from passing through to the wearer. Key aspects include applicable standards, technical parameters, and operational principles.

Applicable Standards

The tester adheres to global safety regulations such as ASTM F2413 (USA), ISO 20345 (EU), and EN 61340 (IEC). These standards define minimum requirements for electrical hazard (EH) footwear, specifying voltage thresholds and insulation resistance values.

Main Parameters

Voltage Range: Adjustable up to 20 kV AC/DC.

Test Duration: 1–60 seconds (programmable).

Current Limit: ≤5 mA (to prevent shoe damage).

Display: Digital readout for real-time leakage current.

Working Principle

The tester generates a high-voltage electric field between two electrodes, placed inside and outside the shoe. When the shoe’s insulation degrades, current leaks through the material, triggering an alarm. Sensors measure leakage current, and results are compared against standard thresholds.

Test Principle

Electrode Setup: Inner electrode contacts the footbed; outer electrode surrounds the shoe.

Voltage Application: Gradually increases to test voltage (e.g., 18 kV).

Leakage Monitoring: If current exceeds 5 mA, the shoe fails.

Result Analysis: Pass/fail indication and data logging for quality control.

This tester ensures workers in industries like construction, utilities, and manufacturing wear footwear capable of withstanding electric hazards, reducing workplace injuries. Regular testing with calibrated equipment maintains compliance and safety.
