Reference standards
Meets the requirements of ISO4589-3:2017 "Plastics - Determination of oxygen index for combustion behavior - Part 3: High temperature test" standard.
Product Features
High temperature digital oxygen index tester is a special testing equipment for measuring the high temperature oxygen index of plastics, rubber, fiber, foam plastics, film, film, paper, textiles and other materials.
Technical parameters
1. Test temperature: continuously set from room temperature to 150 ℃;
2. Temperature deviation: ± 1% ℃;
3. Oxygen concentration (oxygen index): It is a digital direct reading. Resolution: 0.1%.
4. Oxygen concentration (oxygen index) sensor: imported from the United States.
5. Gas supply pipeline: flow meter, pressure gauge, and needle valve.
6. Two pressure gauges provide oxygen output pressure and nitrogen output pressure respectively, and the pressure can be adjusted by adjusting the valve.
7. Measurement range: 0~100%/O2, resolution: 0.1% L/min
8. Measurement accuracy: Level 2.5
9. Combustion cylinder: Quartz glass cylinder, inner diameter: 75mm, height: 450mm
10. Gas flow velocity at the top of the combustion cylinder: 90mm ± 10mm/s
11. Gas flow velocity inside the combustion cylinder: 40mm ± 2mm/s
12. Input pressure: adjustable from 0.25 to 0.5 Mpa
13. Flow meter: one for oxygen and one for nitrogen, with a range of 1-10L/min and a resolution of 0.1L/min
14. Oxygen and nitrogen mixed gas inlet: including stabilizing valve, flow regulating valve, and mixing chamber.
15. Igniter: Special propane handheld electronic firearm. Using copper pipes with a diameter of 2.0mm, the flame can be adjusted to spray 16mm ± 4mm vertically downwards from the outlet.
16. Timer accuracy: ± 0.1/s/h.
17. Glass beads: diameter 4.5mm, filling height 95mm;
18. Sample clamp: one set of hard self-supporting material and one set of soft material clamps;
19. Heating system: Nickel chromium alloy rapid heating electric wire is used, which is wound in sections on a glass tube to ensure uniform temperature inside the test cylinder
20. Temperature measurement system: Mineral insulated heater thermocouple ￠ 1.5mmmm
21. Gas source: Oxygen and nitrogen with a purity of over 98% (to be provided by the purchaser);
22. Power requirements: AC220 (± 10%) V/50HZ;
23. Dimensions: L630 * W350 * H655 (unit: mm);
