- The report was prepared by Snow Zeng and approved by Tony Wu at Waltek Testing Group HCT (Shenzhen) Co., Ltd.
- No equipment modifications were required during testing.
- A decision rule was applied in accordance with the applicable test report form.
Standards & Compliance
The ETENWOLF S0 Mini Bicycle Pump was tested against the following harmonized European standards, which support compliance with the EU EMC Directive (2014/30/EU):
| Standard | Description |
|---|---|
| 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 — Limits for harmonic current emissions (equipment input current ≤16 A per phase) |
| EN 61000-3-3:2013+A2:2021 | Electromagnetic compatibility — Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems |
These standards collectively assess the EMC emission profile of motorized household and similar equipment, ensuring the ETENWOLF S0 does not generate excessive electromagnetic interference under normal operating conditions. The use of the TRF (Test Report Form) TRF EN IEC 55014-1: 2021-EMC-001-V01 confirms alignment with the structured reporting methodology defined by the standard.

The CE-EMC test report WTH25H09245616E is valid as supporting technical documentation for the CE marking of the ETENWOLF S0 within the European Economic Area. Validity is subject to the product design remaining unchanged from the tested sample configuration. Any hardware or firmware modification affecting electromagnetic characteristics would require re-evaluation.
Frequently Asked Questions
- What does CE-EMC certification mean for the ETENWOLF S0 pump?
-
CE-EMC certification means the ETENWOLF S0 has been independently tested and confirmed to meet European electromagnetic compatibility standards. Specifically, it does not emit electromagnetic disturbances above the limits defined in EN IEC 55014-1:2021, ensuring the device will not interfere with other electronic equipment during normal use.
- Which standards were used to test the ETENWOLF S0 for CE-EMC compliance?
-
The ETENWOLF S0 was tested against four harmonized EU standards: EN IEC 55014-1:2021 (emissions), EN IEC 55014-2:2021 (immunity), EN IEC 61000-3-2:2019+A1:2021 (harmonic current emissions), and EN 61000-3-3:2013+A2:2021 (voltage fluctuations and flicker). All tests returned a Pass result.
- Who conducted the EMC testing for the ETENWOLF S0?
-
The EMC testing was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an independent third-party testing laboratory based in Shenzhen, Guangdong, China. The report reference number is WTH25H09245616E, issued on 2025-09-19.
- Is the CE-EMC test report still valid if the product design changes?
-
No. The test report WTH25H09245616E is valid only for the specific hardware configuration of the ETENWOLF S0 as tested. Any design change that could affect electromagnetic emission characteristics — such as motor, circuitry, or shielding modifications — would require a new EMC evaluation and updated test report.
