Car seat foam performance tester
Applicable standards:
GB/T 6670-2008"Determination of falling ball resilience of soft foam polymeric materials" : This standard specifies the test method of falling ball resilience of soft foam polymeric materials, which is suitable for the resilience test of car seat foam.
ASTM D3574Standard Test Methods for Flexible Cellular Materials - Slab, Bonded, and Molded Urethane Foams: This is an American Society for Materials and Testing （ASTM） standard that covers a variety of test methods for flexible honeycomb materials （including polyurethane foam）， including tensile, compression and other performance tests, which are applicable to the relevant performance tests of automotive seat foam.
Main parameters:
| Parameter | Description |
|---|---|
| Test type | Depending on the characteristics of the foam material and test needs, the tester may support various test types such as tensile, compression, rebound, and collapsible hardness tests. |
| Test range | The test range of the tester should cover common performance parameters of automotive seat foam materials, including tensile strength, elongation at break, compression deformation, resilience, compressive hardness, etc. |
| Accuracy and resolution | The accuracy and resolution of the tester determine the precision and reliability of test results. Generally, the tester must have high accuracy and resolution to ensure the accuracy of measurements. |
| Sample size | The tester usually has specific requirements for sample dimensions. For example, tensile test samples may require stamping with a specific die, while compression and rebound tests may need samples of specific sizes and shapes. The tester must adapt to the required sample dimensions. |
| Test speed | Test speed refers to the rate at which the tester applies load or displacement during testing. Different test types may require different speeds, so the tester must support adjustable test speeds to meet diverse requirements. |
| Data acquisition and processing | The tester must be equipped with an advanced data acquisition and processing system capable of real-time data recording during tests and subsequent analysis. This helps users accurately assess the performance characteristics of foam materials. |
| Safety performance | The tester must include comprehensive safety features, such as overload protection and an emergency stop button, to ensure the safety and reliability of the testing process. |
