摘要
通过对比ISO 362—1:2007与ISO 362:1998噪声标准在测试要求上的主要差异,可知ISO 362—1:2007在测试仪器、测量场地、测试环境和测量车辆准备4个方面提出更严格的要求。ISO 362—1:2007采用的测试方法比ISO 362:1998更复杂,主要体现在参考点、测试挡位和测试环节的选择以及进线速度的确定和数据处理与计算等5个方面。最后,通过某一样车依据两个标准分别进行测试,获取测试结果的差异。
By comparing the main differences in test requirements between noise standards ISO 362-1 ： 2007 and ISO 362 ： 1998, it is clear that ISO362-1 ： 2007 has more strict requirements on test instruments, test site, test environment and test vehicle preparation. The test method used in ISO362-1：2007 is much more complicated than that in ISO362：1998 in respects of selections of reference point, gear position and test items as well as the determination of approaching speed and data processing and so on. Finally, the noise measuring test is conducted on a sample vehicle as per two standards respectively with the differences of test results obtained.
