[PSES] Length of coiled cables

2012-09-20 Thread Kim Boll Jensen
Hi

 

I remember to have seen an official definition of how to define the length
of a coiled cable. This is very interesting when testing EMC burst on cables
over 3 meter. When is a coiled cable 3 meter?

 

Especially I need a definition for medical devices under EN 60601-1-2.

 

Best regards,

 

Mr. Kim Boll Jensen

CISPR 24 says that:

  Coil cables (such as keyboard cables) shall not be intentionally
  stretched during testing. For such cables, the length specified in
  the table notes refers to the stretched conditions.

but not sure about the other standards.

Tom
