What are the RoHS testing items for electric ovens in the EU?

Electric ovens, as household electrical appliances, must comply with RoHS Directive 2.0 (2011/65/EU) and its amendment (EU) 2015/863 when exported to the EU. Depending on their structure and material composition, RoHS testing must cover 10 restricted hazardous substances in both metallic and non-metallic components.
I. RoHS Testing Items for Electric Ovens (10 items in total)
Item No. Hazardous Substance Chemical Symbol Limit
1 Lead (Pb) ≤1000 ppm (0.1%)
2 Mercury (Hg) ≤1000 ppm
3 Cadmium (Cd) ≤100 ppm (0.01%, strictest)
4 Hexavalent Chromium (Cr⁶⁺) ≤1000 ppm
5 Polybrominated Biphenyls (PBBBs) ≤1000 ppm
6 Polybrominated Diphenyl Ethers (PBDEs) ≤1000 ppm
7 Di(2-ethylhexyl) Phthalate (DEHP) ≤1000 ppm
8 Butylbenzyl Phthalate (BBP) ≤1000 ppm
9 Dibutyl Phthalate (DBP) ≤1000 ppm
10 Diisobutyl Phthalate (DIBP) ≤1000 ppm ppm
Note: The first six items are original RoHS directive requirements; the last four phthalate plasticizers have been mandatory for all electrical and electronic equipment (including household appliances) since July 22, 2019.
II. Key Testing Points by Material (Typical Components of Electric Ovens)
1. Metal Components (e.g., outer casing, heating element bracket, screws, thermostat metal casing, wiring terminals)
Testing Items: Only 4 heavy metals need to be tested.
Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (Cr⁶⁺)
Common Risk Points:
Surface plating (may contain hexavalent chromium)
Solder (traditional solder contains lead; confirm whether lead-free solder is used)
Alloy materials (e.g., zinc alloy die-castings may contain cadmium or lead)
2. Non-metallic Components (e.g., plastic panels, wire insulation, temperature control knobs, internal cables, circuit board substrate, sealing strips)
Testing Items: All 10 items need to be tested.
4 heavy metals + 2 brominated flame retardants (PBBs/PBDEs) + 4 phthalates
Common Risk Points:
Recycled materials added to plastics (may contain brominated flame retardants)
PVC wire insulation (commonly contains...) (Denyl phthalates such as DEHP and DBP are used as plasticizers)
Circuit board solder resist ink and encapsulating adhesive (may contain bromides)
III. Key Considerations
1. Homogeneous Material Separation Testing
RoHS requires testing of "homogeneous materials".
For example: A wire with insulation → the copper conductor (metal) and the PVC sheath (non-metal) must be tested separately.
2. Applicability of Exemption Clauses
Some components may be eligible for RoHS Annex III exemptions, such as:
Lead in high-temperature solder (e.g., used for heating element connections)
Lead in ceramic components (e.g., some temperature control sensors)
However, the basis for the exemption must still be declared for the entire device; compliance cannot be assumed outright.
3. Test Report Requirements
The report must be issued by a third-party laboratory with ISO/IEC 17025 accreditation (DEZEW Testing CNAS Registration No.: L8083).
The report must include:
Product model, sample description
Bill of Materials (BOM)
Testing standard (usually IEC 62321 series)
Comparison of measured values and limits for each substance
IV. Typical Material List for Electric Oven Testing (Recommended)
Component Material Type Number of Test Items
Stainless Steel Shell Metal 4 items
Plastic Control Panel Non-metal 10 items
Internal Power Cord (PVC) Non-metal 10 items
Circuit Board (PCB) Non-metal 10 items
Thermostat Metal Shell Metal 4 items
Heating Element Pin Solder Joint Metal 4 items (Focus on lead)
Door Seal Silicone Strip Non-metal 10 items (Some laboratories may exempt phthalates, but full testing is recommended)
Recommendation: Prioritize laboratories with CNAS/CMA accreditation or EU recognition. Our laboratory ensures reports are valid globally.
V. Relationship between RoHS and Other Certifications
Electric ovens exported to the EU also need to meet the following requirements:
CE Certification (including LVD Low Voltage Directive + EMC Electromagnetic Compatibility + RoHS)
Energy Efficiency Label (ErP Directive) (if applicable)
Food Contact Material Testing (e.g., baking trays, grill racks, etc., parts in direct contact with food require LFGB or EU 10/2011 testing)
Note: RoHS is a component of CE certification. Without RoHS compliance, the CE mark cannot be legally affixed.
Summary
RoHS testing for electric ovens = Metal parts (4 items) + Non-metal parts (10 items)
Key Controls: Lead (solder), hexavalent chromium (electroplating), phthalates (wires/plastics), brominated flame retardants (circuit boards)
