Key Details
The test report covers both Electromagnetic Interference (EMI) emission testing and Electromagnetic Susceptibility (EMS) immunity testing across multiple test categories as required by the applicable standards. Below is a summary of the test scope.
EMI Emission Tests
| Test Item | Frequency Range | Measurement Uncertainty |
|---|---|---|
| Conducted Emissions — AC Mains | 9 kHz – 150 kHz | ±3.74 dB |
| Conducted Emissions — AC Mains | 150 kHz – 30 MHz | ±3.34 dB |
| Radiated Emissions | 30 MHz – 200 MHz | ±4.52 dB |
| Radiated Emissions | 200 MHz – 1000 MHz | ±5.56 dB |
EMS Immunity Tests
| Test Item | Port / Phenomenon |
|---|---|
| Electrostatic Discharge (ESD) | Enclosure |
| Radio Frequency Electromagnetic Fields | Enclosure |
| Electrical Fast Transients (EFT/Burst) | AC Power Port |
| Surges | AC Power Port |
| Injected Currents (Conducted RF) | AC Power Port |
| Voltage Dips and Interruptions | AC Power Port |
EUT Operating Modes During Testing
| Mode | Title | Description |
|---|---|---|
| TM1 | Charge Mode | DC 20V input via adapter |
| TM2 | Working Mode | DC 10.8V internal battery |
The EUT was configured to produce its highest possible emission and immunity stress levels throughout all test phases, in accordance with the applicable operation manual.
Standards & Compliance
The S7 was evaluated against the following harmonised European standards, which support CE marking under the applicable Radio Equipment and Electromagnetic Compatibility regulatory frameworks.
| Standard | 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 — Product family standard |
EN IEC 55014-1:2021 defines limits and measurement methods for radio-frequency disturbance characteristics of electrical household appliances, electric tools, and similar apparatus. EN IEC 55014-2:2021 specifies immunity requirements for the same product category, covering phenomena such as ESD, radiated RF fields, fast transients, surges, conducted disturbances, and voltage dips.
Ongoing compliance is the responsibility of the manufacturer. Any product modification that may affect emission or immunity performance must be re-evaluated to confirm continued conformity.
Validity & Certification Body
This test report was issued on 2025-04-10 and carries reference number WTH25X04079092E. As a test report rather than a time-limited certificate, its evidentiary validity is tied to the product configuration tested. Any change to the hardware, firmware, or power supply configuration of the S7 may require re-testing.

Frequently Asked Questions
- What does CE-EMC certification mean for the ETENWOLF S7 inflator pump?
-
CE-EMC certification confirms that the S7 inflator pump meets the electromagnetic compatibility requirements of the European Union. This means the device neither emits electromagnetic interference above permitted limits nor is it susceptible to external electromagnetic disturbances that would impair its normal function. It is a mandatory requirement for placing the product on the EU market.
- Which standards were used to test the S7, and why do they apply?
-
The S7 was tested to EN IEC 55014-1:2021 (emission) and EN IEC 55014-2:2021 (immunity). These standards form the product-family standard for household appliances and electric tools, the category that portable inflator pumps fall under. Together they cover both outgoing interference and incoming susceptibility.
- Who conducted the EMC testing and is the laboratory accredited?
-
Testing was conducted by Waltek Testing Group (Shenzhen) Co., Ltd., an established third-party EMC and safety test laboratory based in Shenzhen, China. The report was reviewed and approved internally by a qualified manager, and the laboratory’s official stamp is required for the report to be considered valid.
- Does this test report expire, and what triggers a re-test?
-
Unlike some certificates, EMC test reports do not carry a fixed expiry date. However, the results are specific to the tested sample configuration. If the manufacturer modifies the hardware design, power supply, firmware, or any component that could affect electromagnetic performance of the S7, the product must be re-evaluated to confirm that compliance is maintained.
