Key Details
The following table summarises the four harmonised EMC test standards against which the S5C inflator pump was evaluated. All tests were conducted by Waltek Testing Group HCT (Shenzhen) Co., Ltd. on a single representative sample of the product.
| Standard | Full Title | Scope | Result |
|---|---|---|---|
| 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) | Conducted and radiated electromagnetic emissions from the device | Pass |
| 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 of the device to externally generated electromagnetic disturbances | Pass |
| 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) | Harmonic current injection into the public mains supply | Pass |
| 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 | Voltage fluctuation and flicker caused by the device on the public supply network | Pass |
All results confirmed compliance. Following preparation of the required technical documentation and Declaration of Conformity, the CE marking may be affixed to the S5C.
Standards & Compliance
The S5C inflator pump was tested under the EU EMC Directive 2014/30/EU, which sets the essential requirements for electromagnetic compatibility of electrical and electronic equipment placed on the European market. The four harmonised standards applied provide a presumption of conformity with the essential requirements of the Directive.
- Emissions testing under EN IEC 55014-1:2021 verifies that electromagnetic noise emitted by the device does not interfere with other equipment or radio services.
- Immunity testing under EN IEC 55014-2:2021 verifies that the device operates correctly when exposed to electromagnetic disturbances present in a typical home or workshop environment.
- Harmonic current limits under EN IEC 61000-3-2:2019+A1:2021 ensure the device does not inject excessive harmonic currents into the public electricity grid.
- Voltage fluctuation and flicker limits under EN 61000-3-3:2013+A2:2021 ensure the device does not cause unacceptable voltage instability or visible light flicker on the supply network.
Compliance with these standards enables the S5C to bear the CE marking and be legally sold throughout the European Economic Area (EEA). The manufacturer is also required to maintain a Technical File and issue a Declaration of Conformity (DoC) as part of the full CE compliance process.
Validity & Certification Body
This certificate was issued on July 22, 2025 and is based on a single evaluation of a representative sample of the S5C inflator pump. It does not constitute an assessment of the entire production batch or ongoing production quality. The certificate remains valid subject to the product continuing to be manufactured without changes to design, components, or construction that could affect EMC performance. Any such changes would require re-evaluation.

Frequently Asked Questions
- What does this CE-EMC certificate mean for the S5C inflator pump?
-
It means the S5C has been independently tested by Waltek Testing Group HCT (Shenzhen) Co., Ltd. and found compliant with EU EMC Directive 2014/30/EU. This confirms the device neither emits electromagnetic interference beyond permitted limits nor is it unduly susceptible to external electromagnetic disturbances. The CE marking can therefore be applied, allowing the product to be legally marketed across the European Economic Area.
- Which specific test standards were used to certify the S5C?
-
Four harmonised European standards were applied: 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 fluctuation and flicker). Together these cover all major EMC requirements for household appliances and electric tools under the EU EMC Directive.
- What are the input voltage ratings of the S5C?
-
The S5C inflator pump supports DC 5V/3A, DC 9V/3A, DC 12V/2.5A, DC 15V/2A, and DC 20V/1.5A. This multi-voltage input design is consistent with USB Power Delivery (USB-PD) charging profiles, giving the device broad compatibility with modern power sources.
- Does this certificate cover all units produced, or just the test sample?
-
The certificate is based on a single evaluation of one representative sample of the S5C. It does not imply an assessment of the whole production. The manufacturer, Guangdong Bestek Technology Co., Ltd., is responsible for ensuring ongoing production conformity and maintaining the required technical documentation.
