RED FAQ SAR and RF Exposure

Under RED, SAR and RF exposure sit in the Article 3(1)(a) health and safety assessment. The evidence should connect the actual radio configuration to intended and reasonably foreseeable use, not just cite a general CE or lab certificate.

This FAQ helps decide which frequency, power, antenna, body-position, accessory, software, harmonised-standard, and test-report records belong in the RED technical documentation.

Overview

For RED and wireless exposure, start with Article 3(1)(a): radio equipment must protect health and safety. SAR is one exposure metric, not the required method for every radio product. The applicable assessment depends on the frequency, power, antenna, distance from the body, operating mode, and product scenario. Exposure-related harmonised standards listed for RED address specific cases, including wireless communication devices used next to the ear or close to the human body. The evidence file should show the operating frequency bands, , antenna configuration, intended body position, , accessories and software that affect transmission, the applicable OJEU-listed standard or other technical specification, and the test or engineering evidence used to support the conclusion.

Question 1

What SAR and RF exposure evidence is needed under RED?

The RED does not treat or as a separate marketing claim. It is part of the Article 3(1)(a) health and safety essential requirement, assessed through the conformity assessment and documented in the technical documentation.

Answer the exposure question directly: identify the radio equipment, each intentional transmitter, frequency band, , antenna and enclosure configuration, operating modes, intended distance from the body, foreseeable near-body or next-to-ear use, and the standard or technical specification used to evaluate exposure. State whether the evidence is a measurement, another measurement, a calculation, or a standards-based low-power assessment, and why that method fits the scenario.

  • Use Article 10(8) data as a starting point: instructions for intentional transmitters must include frequency bands and maximum radio-frequency power.
  • For devices used next to the ear or close to the human body, check whether the current OJEU references for EN 50360:2017/A1:2023 and EN 50566:2017/A1:2023 cover the product and operating scenario; do not assume those two standards cover fixed, remote, implanted, or every low-power product.
  • Keep the or test report, standard-selection rationale, antenna drawings, radio settings, software version, accessory assumptions, separation-distance assumptions, and engineering judgement with the RED technical documentation.

What and evidence is needed under RED?

Keep evidence that links the actual transmitter configuration to Article 3(1)(a): frequency bands, , antenna and enclosure design, intended and reasonably foreseeable body position, operating modes, accessories, software or firmware affecting transmission, selected standard or technical specification, and the or assessment or test report.

Does a general CE certificate answer the question?

No. A CE mark or certificate is not enough by itself. The technical documentation should show why the specific radio equipment, in its intended and , meets the health and safety requirement for human exposure to electromagnetic fields.

Question 2

How do Article 3(1)(a), Article 10(8), Article 17, and Article 21 fit together?

Article 3(1)(a) is the obligation: radio equipment must protect health and safety. Article 17 is the assessment rule: the conformity assessment must cover intended operating conditions and, for Article 3(1)(a), reasonably foreseeable conditions. Article 10(8) supplies key transmitter facts for intentional emitters. Article 21 is where the supporting technical documentation is anchored.

That means the exposure answer should not be written only as a standards citation. It should be a traceable chain from product facts, to exposure scenario, to standard or technical specification, to test or analysis, to the declaration of conformity.

  • Record the frequency band and used for each intentional transmitter and operating mode.
  • State whether users can hold, wear, mount, carry, or operate the product next to the ear, close to the body, at a fixed distance, or in an installation.
  • Include the standard edition or alternative specification used, and explain any exclusions, partial application, or product differences from the tested configuration.

Question 3

What records should stay in the technical documentation?

The exposure file should be reviewable without project history. A market-surveillance reviewer should be able to see what was assessed, what transmitter configuration was tested or analysed, which standard or specification was used, and why the conclusion still matches the product placed on the EU market.

For RED and , use an evidence map covering the Article 3(1)(a) health and safety requirement, Article 17 use-condition assumptions, Article 10(8) frequency and power information, applicable harmonised standards, test reports, EU declaration, and change-control triggers.

  • Keep product identifiers, hardware revision, antenna layout, enclosure material, radio module data, transmitter power settings, and software or firmware versions that can affect RF output.
  • Keep , , or engineering assessment reports with the tested modes, channels, antennas, accessories, duty cycles, and separation distances clearly tied to the marketed configuration.
  • Reopen the assessment when the antenna, enclosure, radio module, maximum power, firmware, accessory set, user instructions, intended body position, , or market restriction changes.

Question 4

Implementation checklist for SAR and RF exposure

Use the checklist to produce a documented yes, no, or needs-escalation answer for the specific radio equipment, not for a generic product category.

  • Confirm whether the product intentionally emits radio waves and list every transmitter, antenna, operating band, and setting.
  • Classify the use scenario: next to ear, hand-held, body-mounted, close proximity to the body, fixed installation, remote from users, or multiple configurations.
  • Select the current OJEU-listed where it covers the product; if using another specification, document why it is adequate and whether notified-body involvement is triggered for the relevant RED requirement.
  • Tie each or test report to the marketed hardware, software, antenna, accessory, and user-instruction configuration.
  • Update instructions and safety information so users understand the intended use conditions relied on in the exposure assessment.

Question 5

Common SAR and RF exposure documentation mistakes

The main failure mode is mismatch: the evidence exists, but it does not match the product, antenna, firmware, accessory, frequency band, power setting, or use distance being sold in the EU.

  • Do not reuse a module, supplier, or lab report unless the host-product antenna, enclosure, RF settings, installation, and user-position assumptions still match.
  • Do not cite an old standard reference without checking whether the OJEU listing has been amended, withdrawn, restricted, or replaced for the exposure scenario.
  • Do not bury separation-distance or body-position assumptions in engineering notes if the user instructions need those conditions for the assessment to remain true.
  • Do not let a firmware or power-table change ship without checking whether it changes the Article 3(1)(a) exposure conclusion.
