EVS-EN 61482-1-2:2007

This part of IEC 61482 specifies methods to test material and garments intended for use in heat- and flame-resistant clothing for workers exposed to electric arcs. In contrast to the test methods in IEC 61482-1-12 a directed and constrained electric arc in a low voltage circuit is used to classify material and clothing in defined arc protection classes. The test methods specified in this document are aimed to give a decision if arc thermal protection is met under defined conditions. Two protection classes are tested. Protection class 1 and class 2 are safety requirements covering actual risk potentials due to electric fault arcs.
