Standard Test Method for Determining the Protective Performance of Eye and Face Protective Products from Arc Hazards
-
ASTM F2676 provides the test method for evaluating how well eye and face protective products (such as safety glasses, face shields, or goggles) perform when exposed to an electric arc hazard. It is essential for ensuring worker safety in electrical environments where arc flashes are possible.
Key aspects of this standard include:
-
Arc Flash Simulation:
The test method uses a controlled electric arc to simulate real-world arc flash conditions. Protective products are exposed to incident energy, heat, and light produced by the arc. -
Evaluation of Optical and Structural Performance:
This standard assesses both the thermal resistance and optical clarity of protective eyewear and face shields. It measures whether materials deform, ignite, melt, drip, or allow damaging energy to pass through. -
Protective Threshold Energy (ATPV/ELIM Equivalent for Eye/Face):
The testing determines the arc rating or protective performance value (expressed in cal/cm²) at which the product prevents the onset of failure, such as penetration or dangerous heat transfer. This gives workers a clear guideline on the level of arc protection offered. -
Coverage and Design Considerations:
Beyond material integrity, ASTM F2676 evaluates the product’s design—such as curvature, coverage area, and mounting systems—to ensure it shields vulnerable areas of the face and eyes under arc exposure. -
Compatibility with Other PPE:
Since face and eye protection is often worn with helmets, hoods, or respirators, this standard supports testing in realistic configurations to confirm that combined PPE does not introduce gaps or unsafe conditions.
In summary:
ASTM F2676 is the definitive test method for determining how effectively protective eyewear and face shields perform against arc flash hazards. By establishing a protective performance value, it helps employers and workers select appropriate face and eye PPE that aligns with the arc hazard levels they may encounter. -
