This standard specifies the test method for measuring the noise of the tyre mounted on a test vehicle or trailer under coast-by conditions. Coasting refers to the condition in which the engine is off, there is no power drive, the transmission is in neutral, and the test tyre is in a free rolling state. The tyre noise test results of the vehicle method are closer to the actual effect than the trailer method, but the tyre noise is affected by the suspension parameters; the trailer method test results are closer to the actual noise produced by a single tyre. This standard applies to new passenger car tyres and truck tyres. It is neither suitable for measuring the tyre noise (sound field distribution) of vehicles under normal driving conditions, nor is it suitable for measuring the traffic noise and the degree of harm of vehicles at a given position under normal driving conditions.
