The main purpose
The high-temperature oxygen index tester belongs to the flame retardant series of test equipment, which is used to determine the combustion performance of self-supporting vertical strips or thin sheets of plastic materials with a thickness of 10.5mm under test conditions, or dry vertically supported films or films Determination of combustion behavior of materials.
Model: ISO4589
Applicable standard
International Standard: ISO4589-3:1996 "Oxygen Index Determination of Plastic Combustion Behavior - High Tears Test"
BS2782 Part 143ASTM D 2863
Instrument characteristics
1. Has a combustion cylinder with a heating element and preheater. The temperature in the combustion cylinder is adjustable and controllable.
2. The whole process of the test is controlled by a computer, with a high degree of automation. The operator only needs to input the required oxygen concentration value from the keyboard according to the test requirements, and the instrument will
It can automatically track and adjust to stabilize the oxygen concentration at the set value.
3. Directly detect and display the oxygen concentration value of the sample combustion chamber.
4. The automatic ignition mechanism ensures safe and reliable ignition.
5. It is automatically processed by the computer to display each set of test data and judge the reliability of the obtained test data.
technical indicators
1. Test temperature range: 25°C~150°C;
2. Test temperature control accuracy: ±2°C when ≤125°C, ±3°C when >125°C
3. Oxygen concentration setting range: oxygen concentration value 10%~60% (±0.1%);
4. Oxygen and nitrogen flow can be controlled at the set value, control accuracy: ±0.01L/min, resolution: 0.01L/min;
5. Oxygen concentration step size: can be set from 0.1%;
6. Burning time: 1 second to 300 seconds:
7. Igniter flame height: 15~20mm adjustable;
8. Ignition time: 15s±1s;
9. Quartz glass combustion cylinder size: inner cylinder (inner diameter ≥ 75mm, height ≥ 450mm); outer cylinder (the gap between the inner cylinder and the inner cylinder is between 5mm and 10mm, and the height is the same as the inner cylinder).
