ISO

The oxygen consumption rate calculated from the oxygen concentration in the combustion product gas stream, as well as the heat release rate during combustion, are critical parameters for evaluating the combustion performance of materials. Accurately measuring the heat release rate during the combustion process is crucial for predicting fire hazards and for flame-retardant treatments. This process complies with the following test standards:  ISO5660-1/-2, ASTM E1354, ASTM E1740, ASTM E1550, ASTM D5485, ASTM D6113, NFPA 271, NFPA 264, CAN/ULC-S135, and BS 476.
