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.
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.
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.
