Leading you to an educated decision.
When a standard appears in the Official Journal (OJ), it has been harmonized (approved) by the European Committee for Electrotechnical Standardization (CENELEC) and given a number beginning with an EN prefix. The EN stands for European Norm, which indicates all member countries of the EU recognize this standard and will honor it as the norm throughout the European Union. Product and generic standards are two common EMC standards that appear in the OJ.
Product standards describe a product or product-family classification. Generic standards are categorized by the environment that the product will be marketed in: domestic or heavy industrial. If there is no product standard for your device, you are not considered exempt but rather would use generic standards by default.
