I think that protection objective is the right keyword here. If you (re)sell equipment consisting of individual modules put together in one product, you (the company) has to prove that the protection objective was reached by performing a couple of measurements and tests with the product (plus quality control system etc.).
If you (individual or company) put together a system/rack consisting of different compliant components and do not resell it, you are still liable when the ensemble is the source of interference. For the first case you go through a series of tests and you have to fulfill the requirements. For the second case you better follow the installation instructions/recommendations of the individual manufacturers/suppliers. In the case of interference with equipment installed according to the instructions, the manufacturer will also become involved in providing a solution (please correct me if I'm wrong). If the installation was done differently, the individual/company installing the equipment is entirely responsible. My (personal) view...

I understand your point, but I believe that the actual situation is as I have explained it. It simply doesn't make sense that I (my company) can buy a number of products and put them on a shelf, or even install them in a rack, without any EMC issue being raised, but if the manufacturer puts then into a rack for me, he has to spend $$$$ having the rack tested for EMC, and indeed it may not pass, because the acceptable emissions form the items add up to exceed a limit. -- This is my travelling signature, adding no superfluous mass.
