Electric toothbrushes, as small household appliances, must pass RoHS 2.0 testing, which covers the control of 10 hazardous substances. This article provides a complete guide to EU RoHS testing reports for electric toothbrushes.
I. Core Testing Items and Limits (RoHS 2.0 Standard)
| Hazardous Substances | Limit Requirements | Key Components of Concern
| Cadmium (Cd) | ≤100ppm | Batteries, Metal Plating
| Lead (Pb) | ≤1000ppm | Circuit Board Solder, Plastic Housing
| Mercury (Hg) | ≤1000ppm | Switch Contacts, Fluorescent Indicator Lights
| Hexavalent Chromium (Cr6+) | ≤1000ppm | Anti-corrosion Coating of Metal Brackets
| Polybrominated Biphenyls (PBBs) | ≤1000ppm | Flame-retardant Plastic Components (e.g., Motor Housings)
| Polybrominated Diphenyl Ethers (PBDEs) | ≤1000ppm | Flame Retardants for Circuit Boards
| Phthalate Esters (4 items) | Total ≤0.1% | Silicone brush heads, soft rubber grips (DEHP/DBP, etc.)
II. Processing Procedure (5 efficient steps)
1. Sample Preparation
2 complete units (including battery and brush heads) + disassembled parts:
Plastic shell (10-20g), metal bracket (5-10g), circuit board (complete)
Silicone brush heads need to be packaged separately (for phthalate testing)
2. Institution Selection
Qualification Requirements: Must have ISO/IEC 17025 certification (e.g., DEZEW Testing CNAS registration number: L8083)
3. Testing Cycle and Cost
Cycle: Regular 5-7 working days, expedited 3 days (additional 50% fee applies)
Cost: Approximately 1000-2000 RMB per complete unit (varies depending on the number of parts; additional fees apply for disassembled testing of multiple parts)
4. Key Testing Methods
Metal parts: X-ray fluorescence spectroscopy (XRF) initial screening → Non-conformities were accurately determined using ICP-MS.
Plastics/Silicone: Phthalate and flame retardant detection using gas chromatography-mass spectrometry (GC-MS).
Report Requirements: Must include bilingual (Chinese and English), testing standard number (EN 62321), and laboratory accreditation stamp.
5. Report Validity and Maintenance
Validity: 1 year (EU requires annual review). Retesting is required if materials or processes change.
Subsequent Management: Retain the RoHS report of raw material suppliers (at least 5 years) for traceability.
III. Common Problems and Solutions
Problem 1: Excessive phthalate content in brush head silicone.
Solution: Use medical-grade silicone free of DEHP/DBP and provide supplier material certification.
Problem 2: Excessive cadmium content in batteries.
Solution: Purchase lithium batteries compliant with IEC 62133 and require suppliers to provide a RoHS compliance declaration.
Problem 3: Report fails EU customs audit.
Solution: Choose a testing organization with CE marking and ensure the report includes an EC declaration of conformity.
