How To Test The Flame Retardant Effect Of Flame Retardant Fabrics? At present, the flame retardant effect test methods of flame retardant fabrics mainly include the following: Limiting oxygen index (LOI) method: LOI refers to the minimum oxygen concentration required to maintain the candle-like burning of the fabric when combustion occurs in a mixture of oxygen and nitrogen. The larger the limiting oxygen index, the better the flame retardant …
