This test is mainly used for quality control, production control and material … Web- the higher the LOI the lower the flammability. Air contains approximately 21% oxygen and therefore any material with an LOI of less than 21 will probably support burning in an open-air situation. In the LOI test, a candle like sample is supported in a vertical glass column and a slow stream of oxygen/nitrogen mix is fed into the glass column. From lowest (Least flame-retardant) to highest (Most flame-retardant): • HB: slow burning on a horizontal specimen; burning rate < 76 mm/min for thickness < 3 mm or burning stops before 100 mm • V-2: burning stops within 30 seconds on a vertical specimen; drips of flaming particles are allowed. grandparents tax allowance
