Horizontal Vertical Combustion Tester

Horizontal and vertical combustion test chambers are used to simulate early-stage fire conditions in electrical environments. By simulating real-world scenarios, these chambers can assess the fire risk of materials, the flammability of products, and the safety characteristics of flame spread. Horizontal and vertical combustion test chambers can test the burning performance, burning rate, flame spread, burning intensity, and flame retardant properties of materials and products.

Applications

Horizontal and vertical combustion tester is mainly used for measuring the burning performance of plastic, rubber or film at a predetermined fire source, to determine its fire resistance rating. It can be applied not only for the research, production and quality control departments of lighting, low-voltage electrical appliances, household appliances, electrical machine, tools, instruments as well as electrical connections and other electrical and electronic plastic or rubber products and component parts, but also for the type approval of insulation, plastic , fire blocking material or other solid combustible materials industry.

Test Procedures

Equipment and Environment Confirmation: Check that the power supply, gas supply, and flame source of the combustion testing machine are normal. Gas pressure and oxygen concentration must meet standards. The laboratory must be well-ventilated, free of flammable materials, and the temperature and humidity must meet standards.

Sample Preparation: Prepare samples according to different testing standards, as dimensions, shapes, and weights may vary. Ensure correct placement during installation and avoid close contact with the flame source. Preheat after installation to ensure accurate data.

Test Parameter Setting: Set parameters such as temperature, time, gas flow rate, and flame intensity on the control panel. These parameters must meet standards; adjust according to industry standards or product requirements for different materials.

Test Start: Start the testing machine. It will automatically monitor the temperature and heat the sample. Operators must observe according to procedures, paying attention to flame stability and any abnormalities.

Data Recording and Analysis: The testing machine automatically records combustion data, such as time, temperature, and smoke volume. Operators check the data and analyze combustion performance accordingly.

Equipment Cleaning and Maintenance: After testing, clean the flame tube, pipes, clamps, etc. Regularly check safety facilities to ensure stable equipment operation.
