Auditorium chairs are generally placed in batches in auditoriums, conference rooms, cinemas and major theaters, and most of the materials used for auditorium chairs are wood and cloth. As the weather gets hotter and hotter, fire accidents are still fresh in my memory. Therefore, for this kind of auditorium chairs placed in batches, they are also in public places. Fire prevention requirements must be very strict to avoid accidents.

The first step is to select the fireproof and flame-retardant cloth of the auditorium chair to be tested, cut the required amount, and select the fabric flame-retardant function tester (vertical method) for testing. The temperature of the experiment is between 0 ~ 30 ℃, the temperature in the regular interval is selected, and then the atmosphere with 30% ~ 80% relative humidity is selected (also the regular interval is selected).

The second step is to turn on the power supply, then put the cloth into the experimental box, close the door, conduct a preliminary experiment, adjust the igniter to a certain height and temperature, watch the timer, and then adjust the ignition time and duration of the flame according to the relevant data and specifications. After repeated experiments, observe the changes of the cloth to obtain the flame resistance of the cloth. Remember to experiment repeatedly to obtain uniform data, In order to provide the correct fire prevention function.
