Features of the coefficient of variation of parameters of the gas environment in fire in the premises

Abstract

The object of the study is the selec-tive coefficient of variation of danger-ous parameters of the gas environ-ment during the ignition of materials. The measure of the sample coefficient of variation of an arbitrary hazard-ous parameter of the gas environment observed at an arbitrary time interval is substantiated. The representativeness error of the measure of the sampling coefficient of variation, which depends on the value of the measure and the sam-ple size, was determined. The measure allows you to numerically determine its value for an arbitrary observation inter-val. The difference in the measure at the intervals corresponding to the reli-able absence and occurrence of ignition allows to detect the occurrence of igni-tion of the material.
