Products Description
ISO3795-1989 Car Interior Materials Flammability Test Chamber
Product overview:
This equipment uses an integral intake automatic ignition system with a combustion delay of only 0.1 seconds to ensure full combustion of the gas. It is suitable for the evaluation of the horizontal combustion characteristics of interior materials of automobiles (cars, multi-purpose passenger cars, trucks and buses).
The testing machine is composed of a control box, a combustion box body, a combustion blowtorch, a solenoid valve (flow meter), a high-pressure igniter, a thermometer, a signal control line, the upper and lower brackets of the sample, and a fume hood. The control box and combustion box are made of stainless steel, beautiful appearance, smoke and gas corrosion resistance, and the control system has a high degree of automation, with automatic ignition, automatic air supply, automatic timing, automatic end of the test and other functions.
Use environment:
Power supply: single-phase AC220V± 10%, 50/60Hz
Technical parameters:
Mainly used as interior materials for automobiles (cars, multi-purpose passenger cars, trucks and buses).
Ambient temperature: 10 ° C to 35 ° C Relative humidity: 30% to 90%
System Composition
Control devices, combustion chamber, burner, flow meter, specimen fixture, air pipe and fume hood
Control Devices
The control part is installed on the left side of the combustion chamber, which integrates timing, flow regulation, lighting, and fan on the control panel.
Flame Application Timer
0~999.9/S/M/H, can be preset, accuracy ≤0.5s
Burning Timer
0~999.9/S/M/H, accuracy ≤0.5s
Flame Height
38mm, observed through a 38mm flame height gauge, adjustable by flow meter
Burner
Inner diameter is 9.5 mm. It is located in the test cabinet so that the center of its nozzle is 19mm below the center of bottom edge of open end of the sample. It is made of brass and with auto ignition function.
Specimen Holder
U-shaped bracket: made of two U-shaped corrosion-resistant metal slabs, the upper bracket has 6 pin holes, the lower bracket has 6 pins, the support is in the form of 0.25mm diameter heat-resistant wires spanning the frame at 25mm intervals over the bottom U-shaped frame. The plane of the lower side of samples shall be 178mm above the floor plate. The distance of the front edge of the sample holder from the end of the chamber shall be 22mm, the distance of the longitudinal sides of the sample holder from the sides of the chamber shall be 50mm
Test Gas
The gas supplied to the burner shall have a calorific value of approximately 38MJ/m³, such as natural gas, city gas, liquefied gas
Metal Comb
At least 110mm in length, with seven to eight smooth rounded teeth per 25mm
Combustion Chamber
Length: 385mm, depth: 204mm and height: of 360mm. There are ten venting holes with a diameter of 19mm at the bottom of the combustion chamber. The four side walls have 13mm wide ventilation groove near the top. The top of the combustion chamber is provided with a hole for inserting a thermometer. The hole is arranged at the center of the top, and the center of the hole is 20 mm from the inner side of the rear panel. A collecting tray for collecting molten drippings is placed at the bottom of the combustion chamber, and the tray is placed between the two rows of venting holes without affecting the ventilation of the venting holes.
