AIS 113 Tyre Noise Emission Performance Test
The AIS 113 tyre noise emission performance test is a critical procedure in the automotive industry designed to ensure that tyres meet stringent noise and emissions standards. This test evaluates the sound pressure levels produced by tyres under various conditions, with the primary objective of reducing noise pollution and enhancing driving comfort. The test is particularly relevant for passenger vehicles, light commercial vehicles, and motorcycles.
The AIS 113 standard is part of a broader set of regulations aimed at improving road safety and environmental sustainability. By measuring tyre noise emissions, this test helps manufacturers identify areas where improvements can be made to reduce the sound levels generated by tyres during operation. This not only contributes to quieter vehicles but also helps in complying with international noise regulations.
The testing process involves placing a tyre on a specially designed wheel and mounting it onto a rolling road. The tyre is then subjected to various speeds, pressures, and load conditions that simulate real-world driving scenarios. A sound level meter measures the noise produced by the tyre as it rolls over the surface of the test facility. This data is recorded and analyzed to determine if the tyre complies with the specified noise limits.
The AIS 113 test is not only about measuring the noise levels; it also involves assessing the durability and performance of the tyre under different conditions. The test setup allows for controlled environments that can replicate various driving situations, such as urban traffic or highway cruising. This comprehensive approach ensures that tyres are tested in a way that closely mirrors real-world usage.
Compliance with the AIS 113 standard is crucial for automotive manufacturers and tyre producers alike. Non-compliance could result in product recalls, legal action, and damage to brand reputation. Therefore, it is essential for companies involved in tyre manufacturing or vehicle design to have a thorough understanding of this test procedure.
The test setup typically includes advanced instrumentation such as sound level meters, rolling road systems, and pressure measurement devices. These tools are calibrated according to international standards (ISO 9612:2018) to ensure accurate measurements. The rolling road system allows for the simulation of various driving conditions, while the sound level meter provides precise data on noise emissions.
Before conducting the AIS 113 test, tyres must undergo rigorous preparation to ensure they are in optimal condition. This includes cleaning the tyre surface thoroughly and ensuring it is free from any foreign substances that could affect the test results. The pressure of the tyre must also be set according to specified values, which can vary depending on the type of tyre being tested.
The testing process itself involves a series of steps designed to simulate real-world driving conditions. Tyres are subjected to different speeds and pressures while rolling over a specially designed surface. Sound level meters positioned at strategic points around the test facility capture the noise generated by the tyres. This data is then analyzed using sophisticated software to determine compliance with the AIS 113 standard.
The results of the AIS 113 test are reported in terms of sound pressure levels, which are measured in decibels (dB). Compliance with this standard typically requires that the noise level generated by the tyre does not exceed a specified threshold. Failure to meet these requirements could result in non-compliance issues and potential market recalls.
