For certain locations it may be important to use a  cable which retards flame in  case of fire and is self – extinguishing when the  source of fire is removed. This test is carried out on finished cables to verify this property. The sample cable  is hanged in the chamber and is burned through the burner provided in the Instrument for the prescribed time. After the flame is removed, the period of  Burning of cable is noted by a stop watch. After the cable ceases to burn, the Effected area is measured through the scales provided in the chamber.
