Automatic ISO 4589-2 Oxygen Index Tester for Plastics Flammability Testing
Product Description
The ISO 4589-2 Oxygen Index Tester is a high-precision combustion performance testing device developed according to ISO 4589-2:2017 and ASTM D2863 standards. It determines the Limiting Oxygen Index (LOI) of polymer materials including plastics, rubber, textiles, foams, and composites.
Key Features
- Measures minimum oxygen concentration required for material combustion
- Uses imported high-precision oxygen sensor and mass flow controller
- Fully automatic ignition system with single-button operation
- Real-time data display with automatic LOI value calculation
- Superior repeatability and accuracy compared to manual instruments
- Essential for quality inspection, laboratories, and R&D facilities
Standards Compliance
ISO 4589-2:2017 - Plastics - Determination of burning behaviour by oxygen index - Part 2: Ambient-temperature test
Applications
Evaluates combustion characteristics under controlled oxygen-nitrogen mixed gas flow conditions for:
- Plastic products: PE, PP, PVC, PC, ABS
- Rubber materials: NR, SBR, Silicone, Fluororubber
- Textiles: Cotton, polyester, nylon, aramid fiber
- Foam materials: PU, PS, PE foam (density >100 kg/m³)
- Composite materials: GFRP, CFRP, laminated wood
- Building components: Insulators, seals, pipes, sheets
Note: Suitable for solid, laminated, or cellular form products (80-150mm × 10mm × 4-10mm). Not suitable for liquids, powders, or non-self-supporting materials.
