How do you test the combustibility of automotive interior material?

 

 

1. Determine test parameters and requirements: including the size and shape of the test sample, required test equipment and instruments, test conditions, etc. These parameters and requirements can be obtained from relevant standards and specifications.

2. Sample preparation: According to requirements, prepare interior material samples that meet the test size and shape. Make sure the sample surface is clean and free of dust and contaminants.

 

3. Ensure safe conditions: When conducting testing, make sure to do it in a safe place, away from flammable items, with adequate ventilation, and prepare safety equipment such as fire extinguishers. Also, make sure to use appropriate personal protective equipment, such as safety glasses and gloves.

 

1. Ignition test: Place the sample in a vertical sample fixture and use a sample burner or flame ignition source to ignite the least flammable part of the sample. Indicate the duration of the ignition source and whether the sample spontaneously ignites.

 

2. Observe the behavior of the sample: observe the flame diffusion speed of the sample, whether there is dripping during the combustion process, the combustion termination time, etc. Record the necessary observations.

 

3. Specified test time: According to standard requirements, the test is conducted within a specified time, usually a specified time period, such as 10 seconds, 20 seconds, etc. Observe and record the combustion behavior of the sample during this time.

 

4. Smoke density and toxicity testing: Some standards also require testing for smoke density and toxicity, which can be done by collecting the smoke released during combustion and analyzing it using appropriate equipment.

 

5. Result recording and analysis: According to the requirements of the standard, record the test results, including burning rate, burning time, smoke density, etc. Compare test results with relevant standards for analysis and evaluation.

 

It should be noted that the above steps are just a common method, and the specific testing steps may vary depending on standards and specifications. In order to ensure the accuracy and reliability of the test results, it is recommended to refer to the applicable standards and specifications, and to follow the relevant guidelines of the laboratory or professional organization. In addition, before conducting any testing, please ensure that you have sufficient testing experience and expertise, or seek assistance from a professional laboratory.
