Wireless mice need to undergo RoHS testing before being sold in the EU market. RoHS is a mandatory standard established by EU legislation. Its full name is the "Restriction of Hazardous Substances" (Restriction of Hazardous Substances). When wireless mice undergo RoHS testing in the EU, they mainly follow the RoHS directive, which aims to limit the content of certain harmful substances used in electronic and electrical equipment.
Steps for wireless mouse to undergo RoHS testing in the EU:
1. Understand the requirements of the RoHS Directive: First, you need to understand the specific requirements of the RoHS Directive, including the types of restricted substances and maximum concentration limits. At present, the RoHS directive has developed to RoHS 2.0. The test items have been increased from the original six to ten, including lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), Polybrominated diphenyl ethers (PBDEs), di(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP) and ortho Diisobutyl phthalate (DIBP).
2. Prepare samples: Prepare the wireless mouse samples that need to be tested and ensure that they comply with the scope of application of the RoHS directive.
3. Select a detection method: Select an appropriate detection method based on the type of restricted substance and sample characteristics. For example, for the detection of anions and cations, methods such as ion chromatography, ion selective electrode method, and atomic absorption method can be used. For hexavalent chromium in the colorless surface layer, point testing or boiling water extraction can be used. For the detection of substances such as polybrominated biphenyls and polybrominated diphenyl ethers, Soxhlet extraction can be used followed by GC-MS determination.
4. Conduct experimental testing: Test the samples according to the selected method in a laboratory environment. This typically includes steps such as sample preprocessing, analytical measurements, and calculation of results.
5. Result evaluation and reporting: Based on the experimental results, evaluate whether the content of restricted substances in the wireless mouse meets the requirements of the RoHS directive. If the content of all substances is within the limits, the wireless mouse can be considered RoHS compliant. Finally, a test report is issued to record the test process and results in detail.
