IEC 60331-3:2009 Tests for electric cables under fire conditions - Circuit integrity - Part 3: Test method for fire with shock at a temperature of at least 830 °C for cables of rated voltage up to and including 0,6/1,0 kV tested in a metal enclosure
This part of IEC 60331 specifies the test procedure and gives the performance requirement@ including a recommended flame application time@ for cables of rated voltage up to and including 0@6/1@0 kV required to maintain circuit integrity when subjected to fire and mechanical shock under specified conditions. It is intended for use when testing cables of greater than 20 mm overall diameter. It describes the means of sample preparation@ the continuity checking arrangements@ the electrical testing procedure@ the method of burning the cables and the method of shock production@ and gives requirements for evaluating test results. This part of IEC 60331 is applicable to low-voltage power cables@ and control cables with a rated voltage. NOTE Although the scope is restricted to cables with rated voltage up to and including 0@6/1@0 kV@ the procedure may be used@ with the agreement of the manufacturer and the purchaser@ for cables with rated voltage up to and including 3@3 kV@ provided that suitable fuses are used.
