Specifies a test procedure for assessment of falling flaming droplets/ particles when a single vertical electrical insulated conductor or cable, or optical fibre cable, is subjected to defined fire conditions. NOTE - Testing to IEC 60332-1-3 may be performed simultaneously with that to IEC 60332-1-2, if required. Recommended requirements for performance are given in Annex A. IEC 60332-1-3 specifies the use of a 1 kW pre-mixed flame and is for general use, except that the procedure specified may not be suitable for the testing of small single insulated conductors or cables of less than 0,5 mm2 total cross-section because the conductor melts before the test is completed, or for the testing of small optical fibre cables because the cable is broken before the test is completed. Has the status of a group safety publication in accordance with IEC Guide 104.
