Understanding EU RED Requirements and EN 18031 Testing: A Comprehensive Q&A for Device Manufacturers

Written by Palindrome Technologies | Apr 24, 2025 5:45:18 PM

The European Union’s Radio Equipment Directive (RED) 2014/53/EU lays the groundwork for ensuring radio equipment is safe, functional, and interoperable within the EU market. If you're a device manufacturer targeting the EU, this blog will break down what you need to know and do, to comply.

Q1: What is the EU Radio Equipment Directive (RED)?

A: The EU RED is a mandatory regulatory framework that ensures all radio and telecommunications equipment sold in the EU meets essential requirements in the following categories:

  • Health and Safety: Devices must not pose health risks.

  • Electromagnetic Compatibility (EMC): Devices should not interfere with other devices and must tolerate expected interference.

  • Efficient Use of the Radio Spectrum: Devices must use spectrum efficiently to avoid harmful interference.

Q2: Who does the RED apply to?

A: The RED applies to manufacturers, importers, and distributors of radio equipment — this includes:

  • Smartphones and IoT devices

  • Wi-Fi routers, Bluetooth devices

  • Drones, RFID readers, and wireless alarm systems

  • Any equipment that emits or receives radio waves for communication or localization

Q3: How does RED impact device manufacturers?

A: To market products in the EU, manufacturers must:

  1. Prove compliance with the essential RED requirements.

  2. Conduct risk assessments and maintain a technical file.

  3. Affix the CE mark and draft an EU Declaration of Conformity (DoC).

Failure to comply can result in market withdrawal, fines, and reputational damage.

Q4: What is EN 18031 and how does it relate to RED?

A: EN 18031 is a European harmonized standard used to test compliance with RED. It provides structured methods for evaluating:

  • Radio performance

  • Interference mitigation

  • Safety criteria

Testing to EN 18031 demonstrates that your device meets RED requirements — streamlining CE marking and reducing regulatory risk.

Q5: What does EN 18031 device testing involve?

A: The EN 18031 testing process typically includes:

  • Pre-compliance assessment

  • RF performance analysis

  • EMC and safety evaluations

  • Environmental condition simulations

  • Documentation review

Testing can be done in-house (if accredited) or outsourced to a certified testing lab, such as Palindrome Technologies.

Q6: Why choose a lab like Palindrome Technologies?

A: Palindrome Technologies is a trusted lab offering:

  • Expertise in RED and EN 18031 standards

  • Fast turnaround and cost-efficient services

  • Detailed reporting and compliance documentation

Their experience helps OEMs move from development to market faster, with less risk of non-compliance.

Q7: What steps should manufacturers take to meet RED requirements?

Here’s a checklist for RED compliance:

  1. Identify applicable RED requirements
  2. Design the device with standards like EN 18031 in mind
  3. Choose a qualified test lab
  4. Perform compliance testing
  5. Compile a Technical File
  6. Draft and sign the Declaration of Conformity
  7. Affix the CE mark
  8. Keep documentation available for 10 years

Final Thoughts

Navigating EU compliance can be complex, but understanding RED and leveraging tools like EN 18031 testing simplifies the journey. Partnering with experienced labs ensures your product enters the market safely, legally, and confidently.
