Bringing a kitchen electrical appliance to market, even in small volumes, can feel daunting when you consider safety regulations, CE marking, and the potential costs of testing. But if your appliance is relatively simple, and if you make strategic choices early, the process can be much faster, safer, and more economical than people expect.
This post will share some tips on how to keep product certification manageable.
1. Keep It Simple
Some electrical kitchen products are simpler than others. An egg cooker or a water heater is simpler than a blender or a big grill. And simpler means fewer opportunities to be unsafe. In the end, it means more straightforward testing, and a much cheaper way to verify compliance.
2. Reuse Safety-Critical Components with Known Compliance
A critical insight for first-time builders: You don’t need to reinvent every part of the system. The safest, fastest way forward is to use existing, certified components, especially for anything that handles power, heat, or user interaction.
For example:
-
Use a pre-certified heating element rated for your voltage and use case.
-
Source a UL/CE-marked external power supply that eliminates the need to handle mains wiring internally.
-
Choose an off-the-shelf microcontroller module that doesn’t emit radio signals (unless absolutely needed), which avoids additional FCC/EMC hurdles.
This approach significantly reduces the scope and cost of testing. When components are already certified to the relevant harmonised standards, you can presume conformity under Directive 2014/35/EU, which is a major legal advantage.
However, there is a big difference between “I see a UL logo on the component” and “I have picked a component that is certified to the right standard and for which the supplier provided all the documentation”. It is a deep topic.
3. Understand the Low Voltage Directive (2014/35/EU)
Directive 2014/35/EU (LVD) harmonises safety standards across the EU for electrical products operating within certain voltage limits (typically 50–1000 V AC or 75–1500 V DC). For most consumer kitchen appliances, it’s the primary directive governing electrical safety in the EU & UK.
The directive allows manufacturers to self-declare compliance by creating a technical file demonstrating compliance with essential safety requirements. It includes testing to the applicable harmonised European standards (which are listed in the official database on the europa.eu website — typically including “60335” in the name).
By designing your product to fit within these existing frameworks and documenting how each component meets its respective safety role, you improve your odds of passing tests the first time and of putting a compliant product on the market.
You are interested in going for a UL certification (or equivalent, such as ETL, CSA, etc.)? It’s mostly the same process, based on the same base standards — the IEC 60335-1 standard + the specific standard that applies to your product category (it starts with “IEC 60335-2”). The advice contained in this article is all applicable!
4. Design to Limit Your Testing Scope
For instance, if you use a separate external power supply that is pre-certified, you can probably avoid having to test electrical insulation to the same depth.
Similarly, if you use a low-power, non-boiling heating element, you may fall under the less demanding standard EN 60335-2-49 (for food warmers) instead of EN 60335-2-15 (for kettles and water boilers), which involves more stringent testing for boiling safety and pressure.
Typical testing
If you plan to sell both in the USA & Canada and the EU & UK, some tests can probably be done by the same lab at the same time, based on the various standards:
- RoHS: both for EU & UK and some USA states
- Functional safety: both for LVD and UL mark (or equivalent)
- Electro-magnetic compatibility: both for USA (FCC) and for EU & UK
This testing could come in at under US$10,000 for a simple product that uses the right pre-certified modules/components.
5. Document What Matters
Even when self-declaring CE compliance, you must keep a technical file. This should include, among other:
-
A general product description and intended use
-
Component datasheets and certifications
-
Risk assessments and design safety justifications
- Test reports and accompanying data
-
A Declaration of Conformity (DoC)
If all the safety-critical components/modules in your appliance are traceable to an existing safety standard, your overall system becomes easier to defend in front of regulators and more trustworthy to customers.
Conclusion
For early-stage builders of kitchen electrical products, certification doesn’t have to be overwhelming. The smartest path forward is to stay simple, reuse proven components, and align your design with the relevant standards from the IEC 60335 family.
