I suggest to you to send a mail to ETSI. In this way you can have an official answer.

I’m wondering why, or if I’m misinterpreting the requirements. e.g. compare the characteristic severity with the test severity for the example below. Type Parameter Characteristic Severity Test Severity Random frequency range 10- 200, 200-2000 5-20 20-200 I quickly checked the tests for the other classifications (Careful Transportation etc) and none of them require at least the upper frequency range of 2000Hz. This particular test severity that starts below the Characteristic Severity. The base document is IEC 60068-2-64, which I don’t have. Is the ETSI a sub-set of the equipment classes in the IEC document, and the IEC describes additional classifications that would necessitate the entire range listed under the Characteristic Severity? How about the fact that the test severity in this case starts below the characteristic severity range? - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
