The Textile UL94 Horizontal Vertical Flame TesterTechnical Parameters

The Textile UL94 Horizontal Vertical Flame Tester is used to test the textile, appliances and plastic materials parts for the horizontal, vertical It is according to ANSI/UL94, IEC60950-1, IEC695-2-2.

UL94 Horizontal Vertical Flame Tester technical parameters：

1. Sample frame: It consists of a rectangular metal frame. 12 sample fixing pins are installed along the long side of the rectangular frame with a length of 560mm and a width of 150mm. The distances between the sample fixing pins and the bottom edge are 5mm, 10mm and 190mm respectively. , 370mm, 550mm and 555mm, the length of the fixed pin is 30mm.

2. Template: used for sampling for sample drilling.

3. Timing device: time the three marking lines respectively, and the timing stops automatically when each marking line is burnt.

4. Combustion gas source: industrial propane or butane or propane/butane mixed gas (provided by the user)

5. Sample: L560mm*W170mm, 3 pieces each in the warp and weft directions

6. Combustion torch: meet the requirements specified in Appendix A of GB/T5456-2009, and the nozzle diameter is φ0.19mm

7. Flame height: the horizontal distance from the top of the igniter to the yellow flame is (25±2)mm; the vertical distance from the top of the igniter to the yellow flame is (40±2)mm.

8. Ignition timer: 99.99h/min/s can be set arbitrarily, resolution: 0.01s/min/h, precision: 0.1s

9. Delay timer (T1 time, T2 time, T3 time): 99.99h/min/s can be set arbitrarily, resolution: 0.01s/min/h, precision: 0.1s

10. The angle between the axis of the igniter and the surface of the sample: 0°/30°/90° can be converted

11. Ignition system: high-voltage electronic automatic ignition

12. Igniter: adopt automatic movement and manual conversion of angle

13. Dimensions: L920mm×W650mm×H1670mm

14. Test power supply: AC220V±10%, 50HZ.

UL94 Horizontal Vertical Flame Tester working principle：

In the prescribed igniter flame, the vertical direction of the sample surface or the bottom edge of the ignition 10 s. Determine the flame spread on the sample to the three mark lines used respectively time.
