GB / 8323.2 2008 Vertical Flammability Chamber ZY6166B Plastic Smoke Density For Test Lab

Plastic combustion smoke density meter is based on standard GB / 8323.2 2008

and ISO5659-2 “plastic smoke generated part 2 single room method determination of smoke density test method” stipulated in the technical conditions and developed a new type of determination of smoke density test equipment,

the standard is suitable for the determination of plastic than the optical density of smoke generated during burning,

and to maximize the than light density of the test results. It is used to evaluate the smoke performance of plastic under specified conditions.

1. Application:

Combustion product stream through the oxygen concentration of the oxygen consumption and calculate the heat release rate, heat release rate of the material is also the material properties of the combustion products of the combustion burner of the most important parameters, more accurately measure the material during combustion heat release rate, for predicting fire hazard prevention and fire-retardant treatment is extremely important.
