Product Description
45 Degree Combustion Tester is a kind of equipment used to test the combustion performance of materials under 45 degree tilt angle. It is usually used to test whether the materials in construction, furniture, automobile and other fields meet the relevant safety standards, especially for the detection of flame retardant properties.

Furniture materials (e.g. sofas, mattresses)
Plastic and rubber
Automobile interior materials
Wire and cable materials
3. Areas of application
Construction industry: used to test the fire performance of construction materials to ensure that the materials meet fire safety requirements.
Automotive industry: to test the combustion characteristics of automotive interior materials to prevent fire accidents.
Furniture industry: to test the flame retardant properties of furniture materials to ensure the safety of families or public places.
Electronic products: testing the flame retardant properties of electrical shells and accessories.
4. Technical parameters

Specimen size: generally 100mm x 100mm or 200mm x 200mm (according to specific standard requirements)
Burning time: according to the characteristics of the material and experimental requirements
Temperature control range: often have a higher temperature setting range, used to simulate the actual fire environment
Smoke detection: Some high-end equipment is equipped with smoke density testing to help assess the smoke hazard during combustion.
5. Equipment Features
Precise control: able to accurately control the combustion temperature and the source of ignition.
Safety: with overheating protection, automatic power cut off and other safety features.
Compliance with standards: meet the requirements of ISO, UL, BS and other international safety standards.
Multifunctionality: able to test the combustion performance of different materials and support customized testing.
6. Test Standards
UL94: The U.S. burning standard for plastics, testing the burning behavior of materials under vertical and horizontal ignition sources.
ISO 3795: used to test the combustion performance of automotive interior materials.
GB/T 8627-2017: China's standard for the combustion performance of plastics and wire and cable materials.
7. Operation steps
Prepare the specimen and make sure it meets the standard size.
Install the specimen in the test position of the combustion tester and set the temperature and fire source.
Start the equipment and begin the test, observe the burning response of the material at an angle of 45 degrees.
Record data such as burning time, flame spread rate, and smoke production.
Evaluate the flame retardancy of the material based on the test results.
8. Common Problems
Equipment Failure: If the heating element is damaged or the electric circuit fails, the test may not be carried out.
Unqualified materials: Some materials may have too fast flame spreading speed and too much smoke at an angle of 45 degrees, which requires timely adjustment of the production process.
Standards Update: With the continuous updating of standards, the equipment needs to be upgraded and calibrated in due course to comply with the latest industry norms.

FAQ's of 45 degree combustion testing machine:
Q: How does the 45 Degree Combustion Testing Machine operate for flammability assessment?
A: The machine positions the fabric or film specimen at a fixed 45 angle. The burner automatically ignites using methane or propane, and the combustion duration is recorded via a microcomputer timer. Operators monitor results through the digital LCD display and can record data both manually and digitally for comprehensive documentation.
Q: What safety features are built into this combustion testing machine?
A: Safety is prioritized through the inclusion of an acrylic flame shield that protects operators, a ventilation exhaust for smoke and gases, and corrosion-resistant stainless steel construction. Additionally, the specimen holder is robust, and testing is conducted in a controlled, semi-automatic manner to mitigate risks.
Q: When is it appropriate to use this equipment in textile testing?
A: The machine is specifically suitable when fabric or film requires flammability evaluation at a standard 45 angle, as per industry regulations or quality assurance processes. It is commonly used in laboratory settings, manufacturing quality control, and compliance testing for textiles and related materials.
Q: Where should the combustion tester be installed for optimal operation?
A: For safe and effective use, install the machine on a stable benchtop in a well-ventilated laboratory environment. Ensure access to an AC 220V, 50 Hz power supply and an appropriate gas source (methane or propane with 0.1~0.3 MPa pressure). Keep the machine away from sources of excessive moisture or heat.
Q: What is the procedure for conducting a test with this equipment?
A: Place a single specimen (150 1 mm 13 1 mm) in the stainless steel specimen holder. Adjust test parameters using the digital controls, set the ignition time (up to 99.9 s), and start the test. The burner ignites automatically, and combustion time and burn length are measured. Data are displayed immediately and can be recorded as needed.
Q: Why is automatic timing and digital output beneficial for combustion tests?
