Key Details
The certificate documents compliance across four specific electromagnetic compatibility standards. The table below summarizes the tested standards and their scope as stated in the certification document.
| Standard | Full Title | Scope |
|---|---|---|
| EN IEC 55014-1:2021 | Electromagnetic compatibility – Requirements for household appliances, electric tools and similar apparatus – Part 1: Emission (CISPR 14-1:2016 + COR1:2016) | Limits and measurement methods for radio-frequency disturbance characteristics of household appliances and electric tools (emissions) |
| EN IEC 55014-2:2021 | Electromagnetic compatibility – Requirements for household appliances, electric tools and similar apparatus – Part 2: Immunity – Product family standard (CISPR 14-2:2015) | Immunity requirements for household appliances and electric tools against electromagnetic disturbances |
| EN IEC 61000-3-2:2019+A1:2021 | Electromagnetic compatibility (EMC) – Part 3-2: Limits – Limits for harmonic current emissions (equipment input current ≤16 A per phase) | Limits for harmonic current emissions injected into the public supply system |
| 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, for equipment with rated current ≤16 A per phase and not subject to conditional connection | Limits for voltage fluctuations and flicker caused by equipment in low-voltage supply systems |
All four standards were evaluated and the ETENWOLF S3 was found to be fully compliant, granting presumption of conformity with the essential requirements of the EU EMC Directive.
Standards & Compliance
The ETENWOLF S3 inflator pump has been evaluated against the following European harmonized standards under the EU EMC Directive 2014/30/EU:
- Emissions Standard: EN IEC 55014-1:2021 – Controls radio-frequency disturbance emissions from household appliances and electric tools, ensuring the device does not generate electromagnetic interference that could disrupt other equipment.
- Immunity Standard: EN IEC 55014-2:2021 – Verifies that the product can operate correctly in the presence of external electromagnetic disturbances, confirming functional robustness in real-world environments.
- Harmonic Current Limits: EN IEC 61000-3-2:2019+A1:2021 – Ensures the product’s harmonic current emissions into the public supply network remain within permissible limits for equipment drawing up to 16 A per phase.
- Voltage Fluctuation & Flicker Limits: EN 61000-3-3:2013+A2:2021 – Confirms that voltage changes and flicker caused by the product in the public low-voltage supply system are within allowable limits.
Compliance with these harmonized standards provides a presumption of conformity with the essential requirements of the EMC Directive. The manufacturer is authorized to affix the CE marking to the ETENWOLF S3 upon preparation of the required technical documentation and Declaration of Conformity.

Frequently Asked Questions
- What does CE-EMC certification mean for the ETENWOLF S3 inflator?
-
CE-EMC certification confirms that the ETENWOLF S3 cordless tire inflator complies with the European Union’s Electromagnetic Compatibility Directive (2014/30/EU). This means the product has been tested and verified to neither emit electromagnetic interference above permissible levels nor be adversely affected by electromagnetic disturbances in its operating environment, making it legally marketable across EU member states.
- Which specific EMC standards was the ETENWOLF S3 tested against?
-
The ETENWOLF S3 was tested against four harmonized European standards: EN IEC 55014-1:2021 (emissions), EN IEC 55014-2:2021 (immunity), EN IEC 61000-3-2:2019+A1:2021 (harmonic current limits), and EN 61000-3-3:2013+A2:2021 (voltage fluctuation and flicker limits). All tests were conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd.
- Who conducted the CE-EMC testing for the ETENWOLF S3?
-
The testing was performed by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an accredited third-party testing laboratory located in Shenzhen, China. The certificate was issued under Reference No. WTH25H07183669E and signed by Tony Wu, General Manager, on July 22, 2025.
- Does CE-EMC certification cover all regulatory requirements for the ETENWOLF S3 in Europe?
-
CE-EMC certification specifically addresses electromagnetic compatibility under Directive 2014/30/EU. Depending on the product’s full feature set and intended markets, other EU Directives — such as the Low Voltage Directive (LVD) or the Radio Equipment Directive (RED) — may also need to be observed.
