What is a car interior combustion testing machine?
In automotive manufacturing, safety is always a top priority. In recent years, with the rapid development of new energy vehicles, the flame retardant properties of automotive interior materials have attracted much attention. As a professional testing equipment, the automotive interior combustion testing machine has become an important tool to ensure vehicle safety. This article will introduce in detail the definition, use, working principle and related standards of the automotive interior combustion testing machine, and attach a structured data form for reference.
1. Definition of automotive interior combustion testing machine
The automotive interior combustion testing machine is a professional equipment used to test the flame retardant properties of automotive interior materials (such as seat fabrics, dashboards, ceilings, etc.). It simulates real fire scenarios and detects key indicators such as the burning speed, flame spread, and smoke generation of materials under the action of flames to ensure that materials meet national safety standards.
2. Purpose of automobile interior combustion testing machine
Automotive interior combustion testing machines are mainly used in the following scenarios:
1.Materials research and development: Help R&D personnel optimize the flame retardant formula of interior materials.
2.Quality control: Ensure that mass-produced materials comply with industry standards.
3.Regulatory certification: Provide automobile manufacturers with test reports that comply with national or international safety regulations.
3. Working principle of automobile interior combustion testing machine
The testing machine usually completes the test through the following steps:
1. Fix the material to be tested on the test bench.
2. Use a standard flame source (such as a propane flame) to apply flame to the surface of the material.
3. Record the material’s burning speed, flame spread distance, smoke density and other data.
4. Evaluate the flame retardant grade of the material according to preset standards (such as GB 8410-2006).
4. Relevant standards for automotive interior combustion testing machines
The following are common domestic and foreign automotive interior flame retardant test standards:
| Standard name | Scope of application | Main test indicators |
|---|---|---|
| GB 8410-2006 (China) | Automotive interior materials | Burning speed, flame spread |
| FMVSS 302 (USA) | Automotive interior materials | Horizontal combustion performance |
| ISO 3795 (International) | Automotive interior materials | burning rate |
5. Technical parameters of automobile interior combustion testing machine
The following are the technical parameters of a typical automotive interior combustion testing machine:
| Parameter name | Parameter value |
