TOI Fire Testing Equipment for High Temperature Oxygen Index Test Apparatus
TOI High Temperature Oxygen Index Test Apparatus
Introduction:
High Temperature Oxygen Index Test Apparatus belongs to anti flaming test equipment for measuring the combustion performance of the vertical bars or 10.5mm thin plastic material under test conditions.It is also suitable for combustion performance of vertical supporting film or thin film materials .
Standards
- ISO4589-3: 1996 "oxygen index burning plastic behavior of high-temperature test measurement"
- BS2782 Part 143
- ASTM 2863
- NES 715
Characteristics
1. The combustion cylinder with a heating element and a preheater.The temperature of combustion cylinder is adjustable .
2. The computer automatically controls the whole test process. The operator inputs the oxygen concentration value from the keyboard based on the test requirements. The TOI apparatus can automatically adjust the oxygen concentration value in the rangeof setting.
3. Direct detection and display of oxygen concentration value in the sample chamber.
4. Automatic ignition is safe and reliable .
5. The computer automatically handles each set of testdata,and the determining reliability of the testdata .
