IS 11239.12 Horizontal Burning Characteristics Tester
Introduction
The foam horizontal burning characteristics tester is designed
according to the national standard GB/T 8332-2008: the horizontal
combustion method is used to determine the combustion performance
of foam. It is suitable for measuring the horizontal combustion
performance of small samples of foamed plastics with a density of
less than 250kg/m³ under a small flame. The Horizontal Burning
Characteristics Tester is equipped with PLC and touch screen to
realize the intelligent measurement of the experiment, which can
provide the experimenter with convenient and simple operation
process to the greatest extent.
