整车EMC测试哪里可以办理?10m法电波暗室提供精确EMC检测
1.整车EMC测试车辆的选择
同一款车,动力总成可能不同,高低配配置那么多,不可能没一种配置都测,在选择被车车辆时,一般遵循下面的原则:
1)如果车辆存在不同的动力总成配置,那么测试的车辆应该覆盖所有的动力总成配置。
2)相同的动力总成配置,如果存在高低配置,那应该选择高配置的车辆来做试验,对于低配置的车辆依据高配车辆结合零部件测试报告认可。
3)如果该款车既有三厢又有两厢,一般选择三厢来做试验。两厢车依据三厢车的结果结合未覆盖部门的零部件测试报告认可。
总的原则,选择最大化的配置进行试验,未完全覆盖的部分具体问题具体分析。
2.整车EMC测试
一般整车需要做以下测试,跟零部件EMC测试类似,也包括发射测试(EMI)和抗干扰测试(EMS),对于某些整车厂还有主观收音评价测试。
