The single wire and cable vertical burner is suitable for quality control/inspection units and wire and cable manufacturers for acceptance or qualification audits.

The standard recommends two types of flame calibration.

(1) Flame inner flame 50 ~ 60 mm, outer flame 170 ~ 190 mm

 (2) 10g copper head from 100℃ to 700℃ in 45±5S  

If the user uses the flame verification method, the flame calibration device is required as an option. The flame calibration method will not be considered in the first phase of purchase, but can be added later if required. 

I. Scope of application

The single wire and cable vertical combustion tester is designed to evaluate the combustibility of single wires and cables with a conductor diameter greater than 0.8mm or a cross-sectional area of not less than 0.5mm2). It is suitable for research, production and quality control of electrical and electronic products and their components such as lighting equipment, low-voltage electrical appliances, household appliances, machine tools and appliances, motors, electric tools, electronic instruments, electrical instruments, electrical connections and accessories. This model adopts the product structure recommended in GB18380.12-2008 Appendix B on the air mixing structure part, and the details also fully meet the acceptance requirements of quality inspection units.  

Second, the product function characteristics

Single wire and cable vertical burning test is to use the specified size of Bunsen burner and a specific gas source (propane), according to a certain flame height and a certain angle of flame application on the vertical state of the test product timed to ignite, burning duration and burning length to assess its flammability and fire risk.
