Measurement method for noise of motorcycles and mopeds 3.1 General test conditions
Except for the road conditions and climatic conditions of the driving test, the rest shall comply with the relevant provisions of GB/T5378. 3.2 Road conditions
3.2.1 The road conditions for the driving test shall be:
a. Flat road: in line with national first and second-class roads; b. Mountain road: the average longitudinal slope of the road surface shall not be less than 5%; Gravel road: in line with national third and fourth-class roads. C
3.2.2 The test road should be selected from a section with low traffic volume, which is convenient for the vehicle speed and conducive to test safety. 3.3 Climate conditions
Approved by the State Administration of Technical Supervision on November 16, 1995 and implemented on May 1, 1996
GB/T 4570—1995
The climate conditions for driving tests (except for special provisions) are not restricted. Test mileage and mileage distribution
4.1 The total mileage of the durability test includes four parts: running-in mileage, inspection mileage, performance test mileage and driving test mileage. The total test mileage is specified in Table 1.
