The report covers conducted disturbance at mains terminals, disturbance power in the frequency range, and radiated disturbances — the three principal EMC emission categories required under the applicable European harmonised standards for household electrical motor-operated appliances and tools.
Product Information
The Equipment Under Test (EUT) is the S5C inflator pump, manufactured and marketed under the ETENWOLF brand. Below are the key product and applicant details captured in the test report.
| Field | Detail |
|---|---|
| Product Name | Inflator Pump |
| Model Number | S5C |
| Applicant | Guangdong Bestek Technology Co., Ltd. |
| Manufacturer | Guangdong Bestek Technology Co., Ltd. |
| Applicant / Manufacturer Address | No.1, North Gaopu 8th Road, Yuancheng Industrial Park, Heyuan City, Guangdong, P.R. China |
The S5C is a portable electric inflator pump designed for inflating tyres, sports equipment, and other inflatable items. As a motor-operated tool with an electric drive, it falls within the product scope of the EN IEC 55014 series and the EN 61000-3 series of EMC standards.
Key Details
The test programme covered four major EMC measurement categories as outlined in the table of contents of report WTH25H07183672E. Each section was evaluated against the relevant limits defined in the applicable harmonised standards.
| Test Section | Standard Applied | Result |
|---|---|---|
| Conducted Disturbance at Mains Terminals | EN IEC 55014-1: 2021 | Pass |
| Disturbance Power in the Frequency Range | EN IEC 55014-1: 2021 | Pass |
| Radiated Disturbances | EN IEC 55014-1: 2021 | Pass |
| Immunity (General) | EN IEC 55014-2: 2021 | Pass |
| Harmonic Current Emissions | EN IEC 61000-3-2: 2019+A1:2021 | Pass |
| Voltage Fluctuations and Flicker | EN 61000-3-3: 2013+A2:2021 | Pass |
The test configuration included full EUT exercise, documentation of test auxiliary equipment, application of the laboratory decision rule, and measurement uncertainty assessment for each test method. No equipment modifications were required prior to testing. The sample was received on 2025-07-11 and testing was completed within the window of 2025-07-14 to 2025-07-17.
Standards & Compliance
The S5C inflator pump was evaluated against the following harmonised European standards, which fulfil the essential requirements of the EU EMC Directive 2014/30/EU for CE marking purposes.
| Standard | Full Title / Scope |
|---|---|
| EN IEC 55014-1: 2021 | Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 1: Emission |
| EN IEC 55014-2: 2021 | Electromagnetic compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 2: Immunity |
| EN IEC 61000-3-2: 2019+A1:2021 | Electromagnetic compatibility (EMC) — Part 3-2: Limits — Limits for harmonic current emissions (equipment input current up to and including 16 A per phase) |
| EN 61000-3-3: 2013+A2:2021 | Electromagnetic compatibility (EMC) — Part 3-3: Limits — Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems |
Compliance with these standards demonstrates that the S5C does not generate electromagnetic interference beyond permissible limits and maintains adequate immunity to external electromagnetic disturbances, both of which are prerequisites for affixing the CE mark and placing the product on the European market.

CE-EMC test reports of this type are tied to the specific product configuration tested. Any change to the electrical design, motor drive circuitry, or power supply topology of the S5C may require re-testing to confirm continued compliance. The report validity is subject to the product remaining materially unchanged from the tested sample received on 2025-07-11.
Frequently Asked Questions
- What does the CE-EMC test report WTH25H07183672E confirm?
- Report WTH25H07183672E confirms that the ETENWOLF S5C inflator pump passed all electromagnetic compatibility emission and immunity tests required under the EU EMC Directive 2014/30/EU. The product met the limits defined in 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.
- Which EMC emission tests were performed on the S5C inflator pump?
- Three emission test categories were performed: conducted disturbance at the mains terminals, disturbance power in the frequency range, and radiated disturbances — all evaluated under EN IEC 55014-1:2021. Additionally, harmonic current emissions were assessed under EN IEC 61000-3-2:2019+A1:2021 and voltage fluctuation and flicker under EN 61000-3-3:2013+A2:2021.
- Who conducted the EMC testing for the S5C and when was the report issued?
- The testing was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd. Testing took place between 2025-07-14 and 2025-07-17, and the report was issued on 2025-07-22. It was prepared by Snow Zeng and approved by Tony Wu.
- Does this CE-EMC report cover immunity testing as well as emissions?
- Yes. In addition to emissions, the report scope includes immunity requirements evaluated under EN IEC 55014-2:2021, which specifies immunity requirements for household appliances, electric tools, and similar apparatus. The S5C passed both the emission and immunity test categories.
