Hair dryers need to undergo EU RoHS electronic hazard testing. The RoHS directive is a mandatory standard established by EU legislation to restrict the use of certain harmful substances in electronic and electrical equipment. These harmful substances include lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr VI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE). The purpose of the RoHS Directive is to protect human health and the environment and prevent harmful substances from polluting the environment during the production, use and disposal of electronic and electrical equipment.
1. Determine the testing items
The EU RoHS testing project for hair dryers mainly includes the following aspects:
1. Lead (Pb) content detection: The RoHS directive stipulates that the lead content cannot exceed 0.1%. The circuit boards, solder joints and other parts of the hair dryer may contain lead and require strict testing.
2. Mercury (Hg) content detection: Mercury is extremely harmful to the environment and human health. The RoHS directive stipulates that its content cannot exceed 0.1%. Switches, sensors and other components in hair dryers need to be tested for mercury content.
3. Cadmium (Cd) content detection: Cadmium is a highly toxic substance, and the RoHS directive limits its content to no more than 0.01%. Batteries, circuit boards and plastic parts in hair dryers may contain cadmium and must be tested.
4. Hexavalent chromium (Cr VI) content detection: Hexavalent chromium is a strong carcinogen, and the RoHS directive requires that its content cannot exceed 0.1%. The metal parts in the hair dryer may use rust inhibitors or electroplating layers containing hexavalent chromium, and these parts need to be tested.
5. Polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) content detection: These two substances are commonly used flame retardants in electronic equipment. The RoHS directive limits their content to no more than 0.1%. Plastic parts and cords in hair dryers need to be tested.
2. Prepare test data
Before conducting RoHS testing, you need to prepare the following information:
1. Test samples: Provide 2-3 hair dryer samples to ensure that the samples are representative.
2. Circuit schematic diagram: Provide the circuit schematic diagram of the hair dryer so that the testing agency can understand the circuit structure of the product and the parts that may contain harmful substances.
3. Product manual or user manual: Provide the product manual or user manual of the hair dryer so that the testing agency can understand the usage and precautions of the product.
4. Certification application form: Fill in the RoHS test application form and provide detailed information about the product, including product model, specifications, materials used and production process, etc.
5. Parts list (BOM list): List all parts and supplier information in the hair dryer so that testing agencies can trace the source of hazardous substances.
6. PCB diagram (front and back): Provide front and back photos of the hair dryer PCB diagram so that the testing agency can understand the layout of the PCB and the parts that may contain harmful substances.
