The carpet 45° combustion tester test box is composed of ignition timing device, ignition device and safety control system. The combustion box is made of stainless steel. The box should be equipped with a glass observation window, the top of the box is equipped with a smoke exhaust port, and there are a row of ventilation holes in the lower part of both sides. The box is equipped with a sample holding frame device and a horizontal position into 45°.
Scope of application:
It is suitable for carpet combustion performance test to detect the flame retardancy and thermal shrinkage of carpets.
standard:
GB/T 14768-93 Test method and evaluation of carpet burning performance at 45°
Features:
1. The tester is composed of a test part and a control part and adopts an integrated design, which is convenient for on-site installation and debugging;
2. Large observation window, easy to observe the burning state of the sample;
3. The test frame consists of a press frame and a bottom plate. Material: 304 stainless steel. The outer dimension of the pressing frame is 400mm long x 220mm wide, the inner dimension is 360mm long x 180mm wide; the bottom plate dimension is 485mm long x 220mm wide
4. Imported brand high-precision pressure regulating valve to adjust the gas flow and accurately control the flame height of 24mm;
5. The high-precision pressure regulating valve adjusts the combustion pressure to 3.92kPa (400mmH20 );
6. The burner angle can be adjusted horizontally and vertically;
7. Imported Bunsen burner precisely controls flame height and heat release;
8. Advanced industrial appearance and control design, easy to access the sample and burner;
9. Programmable controller 7" touch screen to realize control/detection/calculation/data display.
- Pulse high voltage electronic automatic ignition.
-The timing button cooperates with PLC to automatically record and store the burning time.
