Select EMC tests by starting with the apparatus, its intended use, its electromagnetic environment, and the essential requirements for emissions and immunity.
Use this page to document which harmonised standards, configurations, phenomena, deviations, reports, and technical-file outputs support a Directive 2014/30/EU conformity decision.

A useful EMC test plan is not a copied list of laboratory tests. It explains why the selected standards and assessments cover the apparatus as placed on the EU market, including normal intended operating conditions, representative configurations, relevant electromagnetic phenomena, and any gaps that must be justified in the technical documentation.
First identify whether the item is equipment covered by Directive 2014/30/EU and whether it is apparatus, a component or sub-assembly liable to create or be affected by electromagnetic disturbance, a mobile installation, or part of a fixed installation. Do not select standards before this scope call is made.
Then translate Annex I into test-plan questions: what disturbances can the product generate, what disturbances can it reasonably face in its intended use, and what level of immunity is needed so it operates without unacceptable degradation of that intended use.
Use harmonised standards as evidence only when the references have been published for the EMC Directive and the selected parts actually cover the product's essential requirements. A standard can support presumption of conformity only for the requirements it covers.
For a test plan, list the standard reference, edition or dated reference used for the declaration, product function it covers, phenomena covered, ports or interfaces covered, and any essential requirements left outside its scope.
Check whether the standards matrix, representative configurations, deviation record, test reports, and EU declaration references line up before the apparatus is placed on the EU market.
The EMC assessment must cover all normal intended operating conditions. If the apparatus can run in different configurations, the plan should identify the representative configurations selected by the manufacturer and explain why they are sufficient.
Do not invent numeric limits in the content plan. Limits, test levels, measurement methods, performance criteria, and setups belong in the cited standard, laboratory procedure, or justified technical specification, with the file showing which source supplied each value.
A test plan should make partial use of a harmonised standard visible. If a standard is applied only in part, the technical documentation needs to specify the parts applied and describe the solutions used for the remaining essential requirements.
Where no harmonised standard exists, a harmonised standard is not fully applied, the product is too large for the prescribed facility, in-situ testing is used, or another technical method is selected, the plan should show the technical methodology and evidence rather than implying presumption of conformity.
The final test-plan package should let a reviewer trace the path from product facts to standards, tests, results, deviations, and declaration language. Keep it with the technical documentation, not only in laboratory email threads.
When the product changes, the standards list changes, or a new variant is added, reopen the test-plan selection record and decide whether the change affects the EMC assessment, reports, declaration of conformity, instructions, or CE marking basis.
