Arc Standard EN 61482-2:2020 Performance & Design Requirements

Raising the Bar in Arc Flash Protection A new test standard for arc flash garments, IEC 61482-1-1, has brought stricter requirements to ensure PPE delivers safer, more reliable protection. This change is part of broader updates to IEC 61482-2, reshaping how arc flash clothing is assessed and rated. ELIM – A New Benchmark in Arc Flash Ratings ELIM ATPV EBT

Rating Type Description

0% probability of second-degree burns 50% probability of second-degree burns

50% probability of fabric breakopen

Two Testing Methods, One Goal: Safety Open Arc Test (IEC 61482-1-1) Measures ELIM, ATPV, and EBT50 values using the Stoll Curve. Box Test (IEC 61482-1-2) Uses a contained arc to assess Arc Protection Class (APC 1 or 2) but does not provide an arc rating.

A key feature of the updated test is the introduction of ELIM (Energy Limit Incident) — a performance metric that complements the established ATPV (Arc Thermal Performance Value). While ATPV identifies the energy level where there’s a 50% chance of second-degree burns, ELIM defines the threshold at which there’s 0% chance of such injuries occurring.
