Needle Flame Test Chamber
Electronic Product Flame Test Apparatus , IEC 60695 Needle Flame Test Chamber
Product Introduction of the Needle Flame Test Chamber
It is developed according to the requirements of the standard IEC 60695-11-5, IEC 60335-1, IEC 60950-1, IEC 60065 on the needle flame combustion test, and fully meets the national standards GB4706.1-2005, GB5169.5 and related UL standards new integrated equipment. The device adopts a full-color seven-inch touch operation display screen. At the same time, the horizontal and vertical movement of the pattern clip is controlled by a motor, which can automatically move up and down, left and right without manual dialing.
This test uses simulation techniques to assess fire hazard due to simulating the effect of a small flame due to fault conditions. For other similar products on the market, at the beginning of the test, you need to press the left hand to start the recording time and pull the Bunsen burner to the position where the sample is placed with the right hand. After the visual recording time is up, pull the Bunsen burner back by hand. This instrument is designed to avoid the user's uncoordinated mis-operation as much as possible. When starting the test, press "start" on the touch screen to automatically move the Bunsen burner to the right to the position of the sample. At the same time, the time relay counts. The light will automatically return to the starting position.
Product Features of the Needle Flame Test Chamber
1. Programmable controller touch screen + PLC control, realizing multi-function control/detection/calculation/data display
2. High degree of automation: automatic recording of test time, automatic display of test results, automatic timing, automatic ignition, automatic return of the Bunsen burner after the end of flame application, and the option to turn off the gas or not
3. When starting, you can choose whether to automatically ignite or not
4. The front, back, up, and down advance and retreat of the sample clip can be controlled by touch screen. Start, stop, gas, timing, ignition, save, save, lighting, and exhaust are all controlled by touch screen, and the test can be completed with a touch of fingertips.
5. The timing button cooperates with PLC to automatically record and store the burning time
6. The test time system is automatically recorded and the test results are generated
