RED standards not cited in the OJEU

Yes, but use it carefully. An uncited standard, a draft standard, a withdrawn standard, or a standard cited for a different scope can support the technical rationale, test plan, or design file. It should not be described as giving RED presumption of conformity unless the relevant reference, or relevant part of the reference, has been published in the Official Journal for the essential requirement you are claiming.

For RED, the practical consequence is route selection. Article 17 allows internal production control for Article 3(1) and Article 3(4) assessments, but for Article 3(2) and Article 3(3), where OJEU-cited harmonised standards have not been applied, have only been applied in part, or do not exist, the equipment must be submitted to EU-type examination followed by conformity to type or to full quality assurance for those essential requirements. During an activated internal market emergency, Article 43c can exceptionally allow a Member State to authorise designated crisis-relevant radio equipment without the normally mandatory notified-body procedure if the equipment meets the conditions in that Article.

Start with the requirement, not with the standard number. Identify whether the point is Article 3(1)(a) safety, Article 3(1)(b) EMC, Article 3(2) efficient spectrum use, an activated Article 3(3) requirement, or Article 3(4) common-charger capability. Then map each requirement to the OJEU-cited standard used, the parts applied, and any missing coverage.

Where the cited standard has a notice or restriction, treat the restriction as part of the record. A standard may be listed while still not conferring presumption for a particular clause, parameter, test condition, antenna configuration, receiver parameter, or other limited point. For example, Implementing Decision (EU) 2025/138 cites EN 18031-1:2024, EN 18031-2:2024, and EN 18031-3:2024 with notices covering their rationale and guidance sections and specified implementation options. The technical file should identify any applicable notice and explain how the affected point is assessed. Check the binding OJEU decision and all later amendments; the Commission's consolidated summary is useful for checking but states that it is informational, can be incomplete, and does not itself create legal effects.

For Article 3(2) and Article 3(3), Article 17 is explicit: if the manufacturer has not applied OJEU-cited harmonised standards, has applied them only in part, or no such standards exist, the equipment is submitted to either EU-type examination followed by conformity to type or full quality assurance for those essential requirements.

This does not mean every uncited standard automatically forces the same route. The route depends on which essential requirement the gap concerns and whether an OJEU-cited harmonised standard fully covers the relevant requirement for the exact equipment. The record should identify the gap before choosing the route.

The claim attached to a standard matters. A file can say that an uncited standard informed the test method or design rationale. It should not say that the product is presumed compliant under RED because of that standard unless the relevant OJEU citation supports that claim.

Supplier radio-module reports can be especially easy to overread. They may support part of the assessment, but the finished equipment file still needs to cover the actual host product, antenna configuration, software, intended use, instructions, and any Article 3 requirement not covered by the supplier evidence.
