IEC 61482-1 Method A - Fabrics
IEC 61482-1-1 Method A, Determination of the arc rating (ATPV or EBT50) of flame resistant materials for clothing, commonly used in the EU, is a test method to determine the Arc Rating (ATPV or EBT) of a fabric or a multi-layer combination of fabrics. Prior to testing, samples are laundered five times using ISO Method 6330. For compliance with IEC 61482-2 and to obtain CE Marking, both fabrics and garments must be arc tested. IEC 61482-1-1 Method A is identical to ASTM F1959 with the exception of different laundry preconditioning methods to prepare samples.
