Key Details

The following table captures the primary test parameters evaluated during the CE-LVD assessment of the ETENWOLF S1.

Test Parameter Standard Applied Result
General Safety Requirements for Household Electrical Appliances EN IEC 60335-1:2023+A11:2023 Pass
Electromagnetic Fields – Human Exposure Measurement EN 62233:2008 Pass

Both standards were applied in their most current harmonised forms. EN IEC 60335-1:2023+A11:2023 covers general construction, insulation, leakage current, dielectric strength, mechanical hazards, and abnormal operation tests. EN 62233:2008 governs measurement methods for electromagnetic fields emitted by household appliances with respect to human exposure limits.

All submitted samples were found to fully comply with the requirements of the above specifications. No deviations, exceptions, or conditional passes were recorded.

Standards & Compliance

The ETENWOLF S1 was tested against the following harmonised European standards to demonstrate conformity with the CE Low Voltage Directive:

  • EN IEC 60335-1:2023+A11:2023 — Household and similar electrical appliances – Safety – Part 1: General requirements. This is the primary safety standard for low-voltage household appliances within the European Economic Area. The 2023 revision incorporates updated requirements for electrical insulation, protection against mechanical hazards, abnormal and fault conditions, and marking requirements.
  • EN 62233:2008 — Measurement methods for electromagnetic fields of household appliances and similar apparatus with regard to human exposure. This standard defines the methodology for quantifying EMF emissions to ensure they remain within safe limits for end users.

Together, these standards form the technical basis for the CE marking affixed to the ETENWOLF S1, enabling its lawful sale and distribution within the European Union and EEA member states.

Importers are required to ensure that the product label affixed on the physical unit contains, at minimum, the name and address of both the importer and the manufacturer, in accordance with EU market surveillance regulations.
