IS 11239.12 Horizontal Burning Characteristics Apparatus

Introduction

The foam horizontal burning characteristics apparatus 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 Apparatus 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.
