External use of Limiting Oxygen Index Equipment (LOI)

Limiting Oxygen Index Equipment (LOI) – External services

DESCRIPTION OF THE EQUIPMENT

Limiting Oxygen Index Equipment (Oxygen Index, Fire Testing Technology Limited).

The Limiting Oxygen Index (LOI) equipment is used to determine the minimum concentration of oxygen in an oxygen–nitrogen mixture required to sustain the combustion of a material. This test provides a quantitative measure of flammability, expressed as the LOI value, which is widely used for comparing fire resistance among materials. The sample is mounted vertically and ignited while the oxygen concentration is adjusted until a stable flame condition is achieved. Materials with higher LOI values are considered more flame-resistant. The method is standardized (e.g., ASTM D2863, ISO 4589) and is particularly suitable for polymers and composites.
