Scope (English)

This standard specifies a test procedure for assessment of falling flaming droplet/particle when a single vertical electrical insulated conductor or cable, or optical fibre cable, is subjected to defined fire conditions. This standard 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.
