The testing instrument employsThe product structures recommended in the section on air-mixed gas construction of GB18380.12-2008 fully meet the acceptance requirements of quality inspection authorities. Standards: GB/T18380.1-2008, GB/T18380.11-2008, GB/T18380.12-2008, GB/T18380.21-2008, GB/T18380.22-2008, GB/T19666-2005, GB12972, GB3003, IEC60332, MT818, MT386, ISO5656.

Vertical combustion test for single-core wire and cable is conducted using a specified size Bunsen burner and a specific gas source (propane), applying flame at a certain height and an equal ignition angle to the specimen in a vertical position over a timed period. The flammability and ignition hazard are evaluated based on the time to ignition, duration of combustion, and length of the flame.
