DIN EN 14227 Tyre Noise Emission Performance Test
The DIN EN 14227 test is a critical standard for the evaluation of tyre noise emissions, focusing on the assessment of road noise generated by tyres during their operation. This test is especially important in the automotive sector where reducing noise pollution and improving driving comfort are key objectives. The primary goal of this test is to ensure that tyres meet stringent noise emission requirements set forth by European Union regulations.
The testing process involves several stages, each designed to simulate real-world driving conditions as closely as possible. Specimens must undergo rigorous preparation before the test begins, ensuring accurate and repeatable results. This includes conditioning the specimens in a controlled environment for specific durations to ensure that they are at equilibrium with their surroundings. The specimens are then mounted on specially designed test rigs that can replicate various road surfaces.
The test itself involves rolling the tyre over a defined distance while measuring sound pressure levels using microphones placed strategically around the test rig. The microphones capture audio data which is analyzed to determine the total noise level produced by the tyre during operation. Compliance with the specified limits in DIN EN 14227 ensures that tyres meet the stringent European Union regulations aimed at reducing road noise.
Understanding the importance of this test, our laboratory offers comprehensive services to help automotive manufacturers and suppliers ensure their products comply with these standards. Our state-of-the-art facilities use cutting-edge technology to conduct these tests accurately and efficiently. By leveraging our expertise and advanced equipment, we can provide reliable data that meets or exceeds customer expectations.
Our service includes not only the testing but also comprehensive reporting which provides detailed insights into the performance of each specimen tested. This report serves as a valuable tool for quality managers, compliance officers, R&D engineers, and procurement teams to make informed decisions about product development and improvement.
Scope and Methodology
| Key Parameters | Description |
|---|---|
| Test Rig Design | The test rig is designed to simulate real-world driving conditions, including various road surfaces. |
| Sampling Frequency | Data is collected at a rate of 48 kHz to ensure high resolution and accuracy. |
| Microphone Placement | Microphones are placed at strategic positions around the test rig for comprehensive sound capture. |
| Environmental Conditions | The specimens are conditioned in a controlled environment before testing to ensure accurate results. |
The methodology for conducting DIN EN 14227 tests is meticulously planned and executed. Specimens undergo rigorous preparation, including conditioning them in the required environmental conditions. Once prepared, they are mounted on test rigs designed to simulate various road surfaces. The specimens then roll over a defined distance while sound pressure levels are captured by strategically placed microphones.
The data collected during this process is analyzed using advanced software tools that can accurately interpret the sound emissions generated by the tyres. This analysis helps in determining whether the specimen meets the specified limits set forth in DIN EN 14227. Compliance with these standards ensures that the tyre will perform safely and effectively within the European Union's stringent regulations.
