Dear Jim Just a couple of points on your item 2, which you and most others are probably well aware of anyway...
If you are making 'multifunction' equipment (e.g. a refrigerator with an LCD display and internet browser) you may have to apply two different product-family standards. For the fridge example this could be EN 55014-1 and EN 55014-2 for the domestic appliance functions, plus EN 55022 and EN 55024 for the Internet functions. (Refer to EMCTLA Technical Guidance Note No. 40 at www.emctla.org) A presumption of conformity to the EMCD is only a presumption of conformity. Where the electromagnetic environment or proximity to sensitive devices (such as radio receivers) for the intended use of a product is not adequately covered by the most relevant harmonised standard, there is a possibility that the EMCD's Protection Requirements (Article 4 and Annex III in 89/336/EEC) might not be complied with. In such situations, especially if there are complaints of actual interference related to the product, enforcement actions could be taken against a manufacturer even though his product met the most relevant harmonised EMC standard in every detail.
