Detailed explanation of China RoHS testing project for hair dryers

1. Core standards for China RoHS testing

China RoHS (Management Measures for the Restriction of Hazardous Substances in Electrical and Electronic Products) is implemented in accordance with the GB/T 39560 series of standards, focusing on the control of the limit requirements of six types of hazardous substances in electronic and electrical products. Testing needs to be classified and tested in combination with product materials (metal/non-metal):

Note:

1. Metal materials only need to test the first four items (lead, mercury, cadmium, hexavalent chromium);

2. Non-metal materials need to be fully tested (including flame retardants PBB/PBDE).

2. Key parts and risk points for hair dryer testing

1. Circuit boards and welding points: high-risk areas for lead (solder) and cadmium (coating), which need to be screened by X-ray fluorescence spectroscopy (XRF);

2. Plastic casings and wires: may contain flame retardants PBB/PBDE, which need to be tested by chemical dissolution method;

3. Metal parts (such as heating wires): hexavalent chromium (rust-proof treatment residue) needs to be tested.

3. Testing process and material preparation

1. Process steps:

- Select a certification body: such as Shenzhen Huancewei, Xunke Standard and other laboratories with CMA/CNAS qualifications;

- Submit materials: including product samples (2-3 units), circuit schematics, BOM tables (including supplier information), PCB front and back pictures;

- Split test: sent for inspection by material classification, the laboratory uses XRF, gas chromatography and other equipment for analysis;

- Obtain report: After passing, the "China RoHS Declaration of Conformity" and test report will be issued.

2. Key documents:

- Product manual (including material list);

- Environmental protection logo design draft (need to mark the content of harmful substances and environmental protection use period).

IV. Notes

1. Compliance labeling: Products that pass the test must be affixed with a green "e" label and an environmentally friendly use period label. Products that do not meet the standards shall not be sold in the Chinese market;

2. Expanded material monitoring: China RoHS 2.0 plans to add four new tests, including phthalates (such as DEHP and BBP). It is recommended that companies conduct supply chain checks in advance;

3. Cost optimization: By integrating EU RoHS and China RoHS testing projects (such as sharing XRF initial screening data), the cost of repeated testing can be reduced.

Summary: RoHS testing of hair dryers in the Chinese market must strictly distinguish between material types, complete six hazardous substance screenings according to GB/T 39560 standards, and standardize label management. It is recommended that companies choose authoritative laboratories and optimize the supply chain in advance to cope with future regulatory expansion.
