Length 350mm Single Cable Flammability Ul 94 , Blue Vertical Flammability Test
Scope of application:
This machine is suitable for the flammability test of various wire and cable insulation covering material PE, PVC and SRPVC. During the test, according to GB/t18380.11-2008 test standard. The two ends of the specimen are fixed and perpendicular to the metal cover of the metal plate. Lighted torch, make the tip of the blue inner cone touch the specimen surface and keep burner and vertical axis 45 °.
Meet the standard:
Conformity to GB/t18380.11-2008 test standard production.
Vertical combustion test method
This standard specifies the experimental method and experimental requirements for the vertical combustion of a single insulated wire or cable under flame conditions.
The experimental method specified in this standard does not apply to a small line with a diameter of less than 0.8mm or less than 0.5mm2, because its conductor will be melted before the end of the experiment.
Before the test, all samples should be in the temperature of (23 + / - 5) ℃, relative humidity (50 + 20) % reach thermal equilibrium conditions (with at least 16 h).
If insulated wire or cable surface with paint or varnish coating, the specimen shall be placed under (60 + 2) ℃ temperature 4 h, then the above processing.
Main features:
The equipment is applicable to the determination of the Nondelayed combustion performance of the wire by direct combustion of the ignition source.
The equipment is mainly composed of control box, vertical combustion test box and burner.
Main parameters:
All technical indicators meet the standard.
The combustion gas USES a pure 95% propane gas.
Internal diameter of nozzle: 12.0 mm, nozzle outlet 7.0 mm.
Control box length 350mm, width 340mm, high 445mm.
The metal cover is 430mm long, 300mm wide and 1210mm high.
Vertical combustion test was tested by test wire cable length: 600 + 25mm
