Standards & Compliance
The ETENWOLF S1 was tested against the following harmonized European standards, which support conformity with the CE marking Electromagnetic Compatibility (EMC) Directive 2014/30/EU. All standards listed are the versions specified in the original test report.
| Standard | Title | Scope |
|---|---|---|
| EN IEC 55014-1: 2021 | Electromagnetic Compatibility – Requirements for Household Appliances, Electric Tools and Similar Apparatus – Part 1: Emission | Conducted and radiated emissions from motor-operated and thermostatically controlled appliances |
| EN IEC 55014-2: 2021 | Electromagnetic Compatibility – Requirements for Household Appliances, Electric Tools and Similar Apparatus – Part 2: Immunity | Immunity requirements for the same equipment category |
| EN IEC 61000-3-2: 2019+A1:2021 | Electromagnetic Compatibility – Limits for Harmonic Current Emissions | Limits for harmonic current emissions for equipment with input current up to and including 16 A per phase |
| EN 61000-3-3: 2013+A2:2021 | Electromagnetic Compatibility – Limitation of Voltage Changes, Voltage Fluctuations and Flicker | Limits for voltage changes and flicker for equipment with rated current up to and including 16 A per phase |
These standards are published by the International Electrotechnical Commission (IEC) and adopted as harmonized European Norms (EN) by CENELEC. Conformance to these standards provides a presumption of conformity with the essential requirements of the CE EMC Directive, enabling the CE mark to be affixed to the product for distribution in the European Economic Area.

Frequently Asked Questions
- What does CE-EMC certification mean for the ETENWOLF S1?
-
CE-EMC certification confirms that the ETENWOLF S1 portable tire inflator meets the electromagnetic compatibility requirements of the European EMC Directive 2014/30/EU. This means the product does not generate electromagnetic interference beyond permitted limits and is sufficiently immune to external electromagnetic disturbances. It is a mandatory requirement for legally placing the product on the market within the European Economic Area.
- Which specific standards were used to test the ETENWOLF S1 for CE-EMC compliance?
-
The ETENWOLF S1 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 emissions), and EN 61000-3-3: 2013+A2:2021 (voltage fluctuations and flicker). All tests resulted in a Pass.
- Who conducted the CE-EMC testing for the ETENWOLF S1?
-
Testing was conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd., an accredited EMC testing laboratory based in Shenzhen, Guangdong, China. The report was prepared by Snow Zeng and approved by Tony Wu. Testing took place from 2025-12-15 to 2025-12-19, with the report issued on 2025-12-25.
