How to get an EN 300 440 Test Report

An EN 300 440 test report is not about "buying a certificate," but rather an official technical document issued by a qualified laboratory after conducting radio frequency (RF) spectrum testing on Short Range Devices (SRD) in accordance with ETSI EN 300 440. It is typically used for EU CE-RED compliance to prove that the product's transmission power, occupied bandwidth, spurious emissions, frequency tolerance, and other parameters within the 1 GHz–40 GHz range meet the EU radio spectrum requirements.

What is the EN 300 440 Standard?

EN 300 440 (Full name: Short Range Devices — Harmonised Standard for access to radio spectrum) is an EU harmonized standard published by ETSI, applicable to:

1.2.4 GHz wireless keyboards, mice, and remote controls

2.Zigbee / Thread / BLE short-range devices

3.868 MHz / 915 MHz class SRD devices

4.Certain low-cost wireless modules operating in the 1 GHz–40 GHz range

5.Non-cellular, non-broadcast, non-radar low-power RF equipment

Common Accompanying Standards:

Who Needs an EN 300 440 Test Report?

As long as a product has wireless transmission capabilities and falls under the category of short-range devices, EN 300 440 should generally be considered:

1.Smart home appliance remote control modules

2.Bluetooth sensors and beacons

3.Wireless access control systems and card readers

4.IoT terminals

5.RF remote controls

6.Complete products with built-in wireless modules

Note: Even if the "power is very low," as long as it transmits RF, it may fall within the scope of the EU Radio Equipment Directive (RED 2014/53/EU).

Who Issues the EN 300 440 Test Report?

The formal path is:

1.An ISO/IEC 17025 accredited laboratory (e.g., JJR) conducts the testing.

2.The laboratory issues the official EN 300 440 test report.

3.The manufacturer compiles the Technical File / Technical Documentation.

4.The manufacturer or eu authorized representative signs the EU Declaration of Conformity (DoC).

5.The product is affixed with the CE mark.

Whether the involvement of a Notified Body (NB) is required depends on:

1.Whether fully harmonized standards are used

2.Whether specific frequency bands are involved

3.Whether there are software-configurable RF parameters

4.Whether new RED cybersecurity provisions are involved

Many SRD products can use Module A (Internal Production Control); however, this does not mean "no laboratory is needed," but rather it is a combination of "Test Report + Technical File + Self-Declaration."

6 Steps to get an EN 300 440 Test Report

Step 1: Confirm if the product applies to EN 300 440

First, check:

1.Is the operating frequency within 1–40 GHz?

2.Is it short-range and low-power?

3.Is it an SRD, cellular, radar, UWB, or RLAN device?

• 2.4G Wi-Fi/BT Broadband: Usually refers to EN 300 328

• 5G WLAN: EN 301 893

• UWB: EN 302 065

• Sub-1GHz SRD: May also refer to EN 300 220 / EN 300 440

Step 2: Prepare Technical Documentation

Laboratories usually require:

1.Product specifications

2.Circuit schematic diagrams

3.PCB layout diagrams

4.Bill of Materials (BOM)

5.Antenna specifications / gain

6.Draft user manual

7.Software version and RF parameter description

8.Fixed-frequency test software (often required for BT/Wi-Fi)

9.Label / nameplate design

Step 3: Conduct Pre-testing (Strongly Recommended)

Perform a pre-scan using a spectrum analyzer during the R&D phase:

1.Does the transmission power exceed EIRP/ERP?

2.Frequency drift

3.Spurious emissions

4.Occupied bandwidth

5.Antenna matching

Pre-testing can significantly reduce the failure rate of formal testing and the costs associated with rectifications.

Step 4: Send Samples to the Laboratory for Formal Testing

Conventional prototypes:

1.2–3 complete prototypes

2.3–5 prototypes for complex products

3.Products with interchangeable antennas must be tested with high/low gain combinations

Testing environment:

1.Shielded room

2.Semi/Full anechoic chamber

3.Calibrated spectrum analyzers, power meters, and antenna systems

Step 5: get the Formal EN 300 440 Test Report

The report should include:

1.Standard version (e.g., EN 300 440 V2.2.1)

2.Sample configuration

3.Test setup photos

4.Measured curves / spectrograms

5.Data on occupied bandwidth, power, spurious emissions, and frequency error

6.Judgment conclusion (Pass/Fail)

7.Laboratory qualification information

Step 6: Incorporate into the RED Technical File and Sign the DoC

The EN 300 440 report is only one part of RED compliance. A complete technical file must also include:

1.RF report

2.emc report

3.Safety report

4.Exposure assessment

5.Risk analysis

6.User manual

7.DoC (Declaration of Conformity)

8.Software/version management description

Technical files must typically be kept for 10 years after the product is discontinued and are subject to random checks by EU market surveillance authorities.

What are the Estimated Testing Cycles and Costs?

Costs depend on:

1.Number of frequency bands

2.Modulation methods

3.Whether multi-antenna configurations are used

4.Whether rectifications are needed

5.Whether a supplementary EN 18031 cybersecurity assessment is required

Rule of Thumb: Pre-testing costs a little, while rectifications cost a lot; failing to review antennas and power during the design phase makes redoing molds later much more expensive.

Most Common Failure Points for EN 300 440

1.Frequency tolerance exceeded: Insufficient crystal oscillator precision, frequency deviation after temperature changes.

2.EIRP limits exceeded: Miscalculated antenna gain, or failing to retest after changing antennas.

3.Failed spurious emissions: Poor power supply filtering, clock radiation, poor antenna matching.

4.Occupied bandwidth exceeds the mask: Unreasonable modulation parameters or data rate settings.

5.Using certified modules but the complete device still exceeds limits: Overall layout, casing, power supply, and antenna altered the RF performance.

6.Software-configurable RF parameters: No parameter locking mechanism, which RED audits will reject.

7.Ignoring EN 301 489 / EN 62368-1: Assuming "Having an EN 300 440 report = ce compliance is completed."

EN 300 440 Report ≠ ce certificate

This is the most common point of confusion for clients:

1.EN 300 440 Test Report: Proves that RF spectrum items have been tested according to standards and passed.

2.CE-RED Compliance: Requires Technical File + DoC + CE Mark.

3.NB Certificate: Issued by a Notified Body only under specific circumstances.

4.Module Report: Does not directly equate to a complete device report.

In short:

An EN 300 440 report is core evidence within the RED Technical File, not the market authorization itself.

Summary:

To get an EN 300 440 test report, manufacturers must first confirm that their product is a 1–40 GHz short-range wireless device. Then, prepare schematics, PCB layouts, BOM, antenna specifications, and fixed-frequency software, and send samples to an ISO/IEC 17025 laboratory to conduct RF testing according to ETSI EN 300 440. After passing, get the official report, merge it with EMC, safety, and exposure assessment documents into the RED Technical File, sign the eu doc, and affix the CE mark. This report proves spectrum compliance and is part of the RED compliance system, but it is not an independent certificate.

9. FAQ: Common Questions about EN 300 440 Test Reports

Q1: Can we issue the EN 300 440 test report ourselves?

No. Formal reports used for CE-RED compliance must be issued by a laboratory with the corresponding capabilities and qualifications; internal corporate debugging data can only be used for R&D validation.

Q2: Should Bluetooth products use EN 300 440 or EN 300 328?

2.4 GHz broadband frequency-hopping devices usually refer to EN 300 328; however, the specifics are still determined by equipment category, bandwidth, duty cycle, and technical mode.

Q3: The module already has an EN 300 440 report; does the complete device still need testing?

Usually, complete device RF/EMC evaluations are still required. A module report cannot automatically cover changes brought about by the complete device's antenna, casing, power supply, and layout.

Q4: How long is the EN 300 440 report valid?

There is no fixed "1-year expiration." However, when product design, antennas, crystal oscillators, RF parameters, or standard versions change, a reassessment is required.

Q5: What happens if goods are shipped to the EU without a report?

You may face customs detention, delisting from platforms, market surveillance penalties, product recalls, and liability for compensation.
