The safety hat antistatic performance tester is a specialized device designed to evaluate the electrostatic discharge (ESD) protection capabilities of protective helmets used in hazardous environments. This article outlines its applications, technical specifications, operational principles, and adherence to international safety standards, critical for ensuring worker safety in industries prone to explosive atmospheres.
The tester complies with global standards such as EN 13463-1 (ESD for flammable environments), NFPA 701 (fire hazards), and ATEX (explosive atmospheres), ensuring compliance for oil/gas, chemical, and pharmaceutical sectors.
| Parameter | Specification |
|---|---|
| Resistance Range | 10⁶ Ω–10¹² Ω (surface resistivity) |
| Charge Decay Time | 0–999 seconds (programmable) |
| Test Voltage | ±10 kV (adjustable) |
| Sample Dimensions | Up to 300 mm × 300 mm |
| Environmental Control | Temperature/humidity stabilization |
The tester applies a known electrostatic charge to the helmet’s surface and measures the time required for the charge to dissipate. Electrodes and sensors monitor surface resistivity and discharge rates, with software calculating compliance to predefined thresholds.
Charge Application: Simulates static buildup via high-voltage electrodes.
Decay Monitoring: Tracks voltage decay over time to assess ESD risks.
Compliance Validation: Compares results to standards (e.g., EN 13463-1 <10⁹ Ω).
This tester enables manufacturers to develop helmets that prevent spark-ignited explosions, critical for industries handling flammable materials. Its precision and compliance with global standards make it a vital tool for ensuring worker safety and regulatory adherence.
