Key Details
The report is structured across five main test categories, each verified against defined limits under the applicable standards. The table below summarises the key test sections, the methodology applied, and the result for each.
| Section | Test Category | Applicable Standard | Result |
|---|---|---|---|
| Section 3 | Conducted Disturbance at Mains Terminals | EN IEC 55014-1: 2021 | Pass |
| Section 4 | Disturbance Power in the Frequency Range | EN IEC 55014-1: 2021 | Pass |
| Section 5 | Radiated Disturbances | EN IEC 55014-1: 2021 | Pass |
| Section 6 | Immunity — Voltage Fluctuations & Flicker | EN 61000-3-3: 2013+A2:2021 | Pass |
| Section 7 | Harmonics Current Emissions | EN IEC 61000-3-2: 2019+A1:2021 | Pass |
Key procedural details recorded in the report include:
- Measurement uncertainty values were documented for each test section in accordance with standard requirements.
- EUT exercise software and equipment configurations were recorded to ensure test reproducibility.
- A decision rule was formally applied when evaluating pass/fail outcomes relative to limits and measurement uncertainty.
- Test equipment lists and instrument calibration details were included for each section.
- Total report length: 51 pages.
Standards & Compliance
The C2PRO was evaluated against the following European harmonised standards, which satisfy the essential requirements of the EU EMC Directive 2014/30/EU:
| Standard | Title | Scope |
|---|---|---|
| EN IEC 55014-1: 2021 | Requirements for Household Appliances, Electric Tools and Similar Apparatus — Part 1: Emission | Conducted and radiated emissions; disturbance power |
| EN IEC 55014-2: 2021 | Requirements for Household Appliances, Electric Tools and Similar Apparatus — Part 2: Immunity | Immunity requirements for motor-driven and similar devices |
| EN IEC 61000-3-2: 2019+A1:2021 | Electromagnetic Compatibility — Limits for Harmonic Current Emissions | Harmonic current emissions into the public supply network |
| EN 61000-3-3: 2013+A2:2021 | Electromagnetic Compatibility — Limitation of Voltage Changes and Flicker | Voltage fluctuations and flicker in low-voltage supply systems |
These standards collectively address the primary EMC emissions and immunity concerns for battery-powered motor-driven tools sold in EU member states. Compliance with EN IEC 55014-1 and EN IEC 55014-2 is the standard route for CE marking of household and similar motor-operated appliances.
Validity & Certification Body
The test report was prepared and approved by qualified personnel at the issuing laboratory. Report validity is contingent on the product remaining unchanged from the tested configuration. Any modification to the hardware, firmware, or motor drive circuitry of the C2PRO may require re-evaluation.

Frequently Asked Questions
- What does the CE-EMC test report WTH25H11289147E confirm for the C2PRO?
- Report WTH25H11289147E confirms that the C2PRO Wireless Portable Tire Pump passed all required electromagnetic compatibility emissions and immunity tests under EN IEC 55014-1: 2021, EN IEC 55014-2: 2021, EN IEC 61000-3-2: 2019+A1:2021, and EN 61000-3-3: 2013+A2:2021. This supports the product’s CE marking and confirms it meets EU EMC Directive 2014/30/EU essential requirements.
- Which specific EMC tests were conducted on the C2PRO?
- The testing covered five main areas: conducted disturbance at mains terminals, disturbance power in the frequency range, radiated disturbances, harmonic current emissions, and voltage fluctuations and flicker. All five test categories returned a Pass result. Tests were carried out between 2025-11-04 and 2025-11-06 at the Waltek HCT laboratory in Shenzhen.
- Does passing this EMC report mean the C2PRO is fully CE certified?
- This report addresses the EMC component of CE compliance. Full CE marking for a wireless portable tire pump typically also requires assessment under relevant safety directives (such as the Low Voltage Directive or Machinery Directive, depending on classification) and may involve additional documentation. This EMC test report is one essential element of the complete CE technical file.
- Will the CE-EMC certification remain valid if the C2PRO design changes?
- No. The report is valid only for the exact hardware and firmware configuration that was submitted and tested. Any significant change to the motor drive circuit, enclosure, or electronic components of the C2PRO may require a new EMC evaluation to maintain CE compliance.
