Factory equipment, however large, is apparatus and not fixed installation, and if so, is the recommended conformity assessment for these "in situ" testing?

Manufacturers of equipment only supply apparatus. A fixed installation cannot be supplied. Apparatus is installed within a fixed installation. Therefore the Apparatus route to conformity should be followed including all necessary Technical Documentation (i.e. EMC Testing, Risk Analysis etc). The EMC Technical Documentation for this apparatus will then be handed over to the Responsible Person of the specified Fixed Installation who is required to retain it within the Fixed Installation's EMC Technical File. The only exception to this is for apparatus intended for a given fixed installation and not otherwise commercially available where a formal EMC Assessment is not required but must meet the documentation requirements given in the Directive for Fixed Installations. This might include the need to do in-situ testing to demonstrate that the fixed installation EMC characteristics remain unchanged. For any apparatus, ideally EMC testing should be conducted within an EMC Chamber. If this is not possible (e.g. due to its physical dimensions) then 'in-situ' testing should be undertaken. A risk assessment taking into account the tests that cannot be performed and the differing testing techniques employed in-situ will be made and included within the apparatus' EMC Technical Documentation.
