| 4.6 | EMS — Immunity | Voltage dips and short interruptions |
Standards & Compliance
The P100 Ball Pump was evaluated against the following harmonised European standards applicable to household appliances and electric tools under the EU EMC Directive 2014/30/EU.
| Standard | Title | Scope |
|---|---|---|
| EN IEC 55014-1:2021 | Electromagnetic Compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 1: Emission | Limits and measurement methods for electromagnetic emission from equipment in the frequency range 9kHz to 400GHz |
| EN IEC 55014-2:2021 | Electromagnetic Compatibility — Requirements for household appliances, electric tools and similar apparatus — Part 2: Immunity — Product family standard | Immunity requirements covering ESD, radiated RF fields, EFT/burst, surges, conducted RF immunity, and voltage dips |
Compliance with these standards supports CE marking of the product for sale in the European Economic Area. The manufacturer bears ongoing responsibility for maintaining compliance; any product modification that could affect emission or immunity levels must be re-evaluated to confirm continued conformity.

Frequently Asked Questions
- What does this CE-EMC test report confirm about the P100 Ball Pump?
-
The report confirms that the ETENWOLF P100 Ball Pump passed both electromagnetic emission (EMI) and electromagnetic immunity (EMS) evaluations conducted by Waltek Testing Group. The device complies with EN IEC 55014-1:2021 and EN IEC 55014-2:2021, which are the harmonised standards required for CE marking under the EU EMC Directive 2014/30/EU.
- What is the difference between EMI and EMS testing covered in this report?
-
EMI (Electromagnetic Interference / Emission) testing measures the level of electromagnetic noise the device generates — both conducted noise on the power line and radiated noise through the air — to ensure it does not interfere with other equipment. EMS (Electromagnetic Susceptibility / Immunity) testing verifies that the device continues to operate correctly when exposed to external electromagnetic disturbances such as electrostatic discharge, RF fields, power line surges, and voltage dips.
- Does this report cover all CE certification requirements for the P100?
-
No. This report addresses only the EMC (electromagnetic compatibility) requirements. CE marking for a product like the P100 Ball Pump may also require evaluation under additional directives, such as the Low Voltage Directive (LVD) or the Radio Equipment Directive (RED), depending on the product’s features. Separate test reports or declarations would cover those requirements.
- If the P100 design is modified, is this test report still valid?
-
Not necessarily. As stated in the report, any modification to the product that could affect its emission or immunity characteristics must be re-evaluated to confirm that compliance has been maintained. The manufacturer — Guangdong Bestek Technology Co., Ltd. — is responsible for ensuring ongoing conformity after any design change.
