I'm sure John is correct. IMO a DoC without listing each 61000-4-x item with level and performance criteria yields a document worthy of lining a bird cage. (Now then, I wonder how many of mine - even with 61000-4-x:yyyy listed - ended up in a bird cage anyway?)
There will always be some users and system assemblers that will be subjecting a finished system or installation to EMC tests. So, without the basic details these customers can only guess how a product was tested from the product family standard; assuming their final product is in the same family.... EN 61326 (EMC for measurement control and lab equipment) complicates this matter by having it's general immunity requirements plus a few other immunity "environments" in the Annexes. And, it offers a choice of different sets of performance criteria for the 61000-4-x basics; even A for all 61000-4-x if functional safety is a concern. Worse yet, every few years these standards face revision....
