EMC测试标准（CISPR CLASS-B 与 FCC PART 15B区别在于......）

请问下大家.CISPR CLASS-B 与 FCC PART 15B各用途在什么产品上面？我只知道CISPR CLASS-B 标准在88MHZ-224MHZ会比FCC PART 15B要严格3.5DB.我们的产品用于AV类产品.需要做FCC.CE认证.以上两个标准都要做吗？或者只做其中一项？谢谢大家了

我们的产品是电源适配器

FCC的标准限值是要比CISPR的松一些，如果FCC，CE都要做的话，那肯定是要两个标准都要做的；
CE能过的话，那FCC就一定能过了

The FCC and the CE requirements are not equivalent. The CE limit is only lower than the FCC limit in some ranges. Say for example, before 230MHz, the CE Limit is lower than the FCC limit. However, from 230MHz to 960MHz, the FCC Limit is lower than the CE limit. Hence, a product cannot ensure to pass the FCC requirements even though it passes the CE Class B limit. The corresponding limits of FCC and CE are uploaded to this forum for your reference.

Since the test methods and setups are the same for the FCC & CE requirements, you may check the test results against both the limits by yourself with either FCC report or CE report.
