ASTM F2178-12
Standard Test Method for Determining the Arc Rating and Standard Specification for Eye or Face Protective Products

5.2 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.

5.3 This test method specifies a standard set of exposure conditions. Different exposure conditions may produce different results.

5.4 This specification covers the minimum performance criteria for arc resistance and other requirements for eye or face protective products used by workers who may be exposed to thermal hazards of momentary electric arcs or flame.

5.5 The purchaser has the option to perform or have performed any of these tests in order to verify the performance of the eye or face protective product. Claims for failure to meet the specification are subject to verification by the manufacturer.

1.1 This test method and product specification is used to measure the arc rating and specify the requirements for products intended for use as eye or face protection for workers exposed to electric arcs that would generate heat flux values from 84 to 258201;120 kW/m²8201;[2 to 600 cal/cm²s]. Products are tested as sold.

1.2 This test method determines an arc rating for eye or face protective products. The faceshield, safety spectacle, goggle or or other applicable portions of the complete product must meet ANSI Z87.1. This excludes the textile or non ANSI Z87.1 testable parts of the hood assemblies or other tested products. This standard does not measure optical and impact properties (see ANSI Z87.1) but does specify requirements for optical and impact properties.

1.3 The materials covered by this standard are in the form of faceshields attached to the head by protective helmets (hard hats), headgear, hood assemblies, safety spectacles or goggles. Faceshields, safety spectacles or goggles are tested with or without other face and head protective products, for example, sock hoods, balaclavas, sweat shirt hoods or jacket hoods.
