It is hard to argue with the Guidelines! (although, do the EMC Guidelines have the same weight of law as the EMC Directive?)
Glad I buy my DIMM modules here in the states, before all the overhead of EMC testing, and ' instructions accompanying the component that clearly indicate these requirements, the pertinent limitations of use and how to comply without resorting to an EMC specialist', is added to the cost of a simple DIMM. ;-) Doug Massey Product Safety Engineer Advanced Compliance Solutions Ph.

Plug-in cards, such as smart cards or input/output modules, designed for incorporation into computers are apparatus commonly found in retail outlets, and available to the general public. Once cards of this type are inserted in a PC they perform a direct function for the user. They must therefore be considered as apparatus and are, consequently, subject to the provisions of the EMC Directive. This does not mean that they must necessarily be intrinsically compliant >from the EMC point of view in all cases, if this is either impossible or impracticable. However, in such cases, they must be designed in such a way that they become fully EMC compliant (emissions and immunity) when they are installed as intended in the apparatus, in any of its possible variants and configurations, without exceptions, and used in the electromagnetic environment determined by the manufacturer. The instructions accompanying the component must clearly indicate these requirements, the pertinent limitations of use and how to comply without resorting to an EMC specialist (such components are available to non-EMC specialists, for a wide range of applications). The manufacturer has the ultimate responsibility for this decision ...". DIMMs are modules containing one or several chips on a small circuit board, so, if they are available to the general public, I believe, the above applies to them. By the way, according to the same guidelines, integrated circuits are components without a direct function.
