Single wire and cable vertical combustion instrument (quality inspection/testing unit model)
Flame calibration device for vertical combustion instrument of single wire and cableThis single wire and cable vertical combustion instrument is suitable for quality inspection/testing units and wire and cable production enterprises for acceptance or qualification review.
1、 Scope of use
The single wire and cable vertical combustion tester is mainly used to evaluate the combustibility of single wire and cable with a conductor diameter greater than 8mm (cross-sectional area greater than 0.5mm2) or less than 8mm (cross-sectional area less than 0.5mm2). Suitable for research, production, and quality inspection departments of electrical and electronic products and their component parts, such as lighting equipment, low-voltage appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, electrical connectors, and accessories. This product adopts the recommended product structure for the air mixing structure in Appendix B of GB18380.12-2008, and the details also meet the acceptance requirements of the quality inspection unit.

2、 Product functional features
The vertical combustion test of a single wire and cable is conducted by using a Bunsen burner of a specified size and a specific gas source (propane) to ignite the specimen in a vertical state at a certain flame and flame angle. The combustibility and ignition hazard of the specimen are evaluated based on the duration and length of ignition and combustion.

4、 Design standards
GB/T18380.1-2008、GB/T18380.11-2008、GB/T18380.12-2008、
GB/T18380.21-2008、GB/T18380.22-2008、GB/T5169.14-2007
5、 Applicable standards
IEC60332、GB/T19666-2005、GB12972、GB13033、MT818、MT386、ISO5656
Another standard recommends two flame calibration methods:
(1) Flame inner flame 50-60mm, outer flame 170-190mm
(2) The time for heating 10g copper head from 100 ℃ to 700 ℃ is 45 ± 5 seconds
If the user uses the second method to verify the flame, a flame calibration device needs to be selected. The flame calibration method is not currently considered for early procurement, and can be added later if necessary.
