DuPont protective clothing against thermal hazards of an electric arc
We recommend protective clothing made of NOMEX® for protecting people against thermal hazards of an electric arc.
*IEC 61482-1 - Live working - Flame resistant materials for clothing for thermal protection of workers - Thermal hazards of an electric arc :
Scope : This standard specifies test methods to measure the arc thermal performance value of materials intended for use in heat- and flame- resistant clothing for workers exposed to electric arcs.
Heat & Flame Performance criteria :
- Less than 100 mm char length and less than 2 s afterflame after removal from flame, when tested in accordance with ISO 15025, procedure B (bottom-edge ignition) on the outer material
- Determination of arc rating of materials (APTV), when tested with an open electric arc
