Abstract

Heat Release Rates of organic materials are studied in many countries, but there is no mathematical formula to represent their shape. We considered a mathematical expression of the Heat Release Rate Curve by a simple equation. And we also derived the index of degree of combustibility, named 'Burning Index (BI)'. The Heat Release Rate Curve is expressed by the derivative of a probability function of maximum value and has three parameters; an amplitude coefficient, a time width coefficient and an ignition index. BI is in proportion to an amplitude and a time width and in inverse proportion to an ignition index. BI values of cable plastic compounds with flame-retardant material had good relations with the quantity of non-organic ingredients.
