Honda Requirement HES C 206-17 Flammability of Automobile Interior Materials

The HES C 206-17 standard, developed by Honda Motor Company, describes the requirements for the flammability of non-metallic materials used in automotive passenger compartments that have specific combustion resistance requirements stipulated by laws and regulations .

When these materials are subjected to the flammability test, the flammability of the interior materials of the car must comply with the following requirements.

Any of the following characteristics must be met:

• being non-flammable
• self extinguishing
• The burning rate is equal to or less than the values ​​specified in the table for each code and the flame does not spread to the surface.

In addition, the tendency of the burning rate to change depending on the deterioration behavior should either reach saturation at a rate not exceeding the determined burning rate within 336 hours of the deterioration behavior period or show a decreasing rate.

Meanwhile, the flammability test for automobile interior materials must comply with the HES D 6003 standard (HES D 6003 Flammability - Flammability test method for automobile interior materials).

The HES C 206-17 standard defines the technical requirements and test methods for the flammability of automotive interior materials. These standards are not considered valid for the evaluation of all vehicles, as there are many differences between the test conditions in the standards for the evaluation of flammability of automotive interior materials in general, the actual conditions of various automotive interior materials, for example, layout, usage condition and ignition source. However, the HES C 206-17 standard is only for Honda vehicles and is reliable.

For the purposes of this standard,

• Interior material refers to special materials or composite materials used by automotive interior spare parts. Such as backrest, seat cover, seat belt, headrest and so on.
• Burning rate refers to the ratio between the burning distance and the time used to burn this distance, and is usually defined as mm/min.
• Composite material refers to the surfaces of layers consisting of similar or different materials that are tightly joined by different methods such as heat bonding, joining and welding.

Our organization also provides flammability testing services for automobile interior materials within the scope of HES C 206-17 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
