The High-Temperature Oxygen Index (TOI) measuring instrument determines oxygen index at up to 125°C, offering better flammability assessment than traditional methods. As gas temperature increases, the oxygen index decreases. It follows ISO 4589 Part 3 or NES 715 standards, achieving high temps via preheated gas and furnace wall settings. A built-in pump conserves gas between tests, with nitrogen and oxygen bottles connected only during testing.
Application
Evaluating material combustion performance in R&D.
Quality control for product acceptance.
High-temperature safety assessment in industries like aerospace, automotive, and construction.
Standards
ISO 4589-3: Plastics – Oxygen index method (high-temperature test).
GB/T 2406.2 / ISO 4589-2: Plastic oxygen index test (normal/high-temperature).
ASTM D2863: Plastic oxygen index standard.
GB/T 5454-1997: Textile oxygen index method.
NES 714/715: UK oxygen index test standards.
Product Advantages
High-Temperature Precision: Tests up to 200°C with rapid response (10s heating).
Accurate Oxygen Control: ±0.5% concentration accuracy (0–100% range).
User-Friendly Design: Full-color touchscreen with Chinese/English interfaces.
Versatile Testing: Suitable for diverse materials (plastics, rubber, textiles).
Safety Compliance: Meets global standards for reliable data.
Feature
Testing Principle: Vertical sample combustion in oxygen/nitrogen gas flow. Combustion time and oxygen percentage are measured to determine LOI.
Key Components
Heat-Resistant Cylinder: Borosilicate glass (inner dia. >75mm, height >550mm).
Stainless Steel Beads: Enhances gas flow uniformity (4mm dia., 80–100mm height).
Pilot Burner: 2mm inner dia., 400mm length for precise ignition.
Gas Control: Automated oxygen/nitrogen mixing with flow rate 12.1L/min.
