ASTM F2178 - Face Protection

Arc flash testing to ASTM F2178, Standard Test Method for Determining the Arc Rating and Standard Specification for Eye or Face Protective Products, is used to calculate the Arc Rating (ATPV or Ebt) for face shield, hood, and balaclava/goggle PPE products. Testing is performed using the ASTM F2178 Specification and the Arc Rating is determined using a mannequin head mounted with sensors measuring the incident energy and heat transfer through the product as compared to the Stoll Curve. Arc flash hoods are assigned the Arc Rating that is the lowest between the faceshield component and the fabric component of the product.
