During <strong>the</strong> test norupture <strong>of</strong> conduc<strong>to</strong>rs shall appear and voltage must be maintained.For <strong>the</strong> purposes <strong>of</strong> <strong>the</strong> European Construction ProductsDirective <strong>the</strong> survival time serves <strong>to</strong> classify <strong>the</strong> cables in<strong>to</strong> PHclasses from PH15 <strong>to</strong> PH90. The test is considered <strong>to</strong> be passed,if during <strong>the</strong> test no short circuit occurred.Test standardsDIN EN 50200, classes PH 15, 30, 60, 90VDE 0482 part 1IEC 60331-12 Apparatus 830 °CIEC 60331-31 Fire with shock, up <strong>to</strong> 0.6 / 1.0 kV900475300200
