Four national standards for the detection of hazardous substances in electrical and electronic equipment have passed the examination and approval.

Recently, the Secretariat of the "Hazardous Substance Testing Method Working Group" was authorized by the High-Tech Department of the National Standardization Administration Committee to hold a review meeting for four national standards aimed at detecting hazardous substances in electrical and electronic products. These standards, including the "Limitation of Polybrominated Biphenyls and Polybrominated Diphenyl Ethers in Electronic and Electrical Products," have now been officially approved. The four standards reviewed include: "Restriction of Polybrominated Biphenyls and Polybrominated Diphenyl Ethers in Electronic and Electrical Products," "Liquid Chrome (Cr) Detection Method for Restricted Substances in Electrical and Electronic Products," "Detection Methods for Lead (Pb), Mercury (Hg), and Cadmium (Cd) in Electrical and Electronic Products," and "Rapid Screening of Lead, Mercury, Cadmium, Chromium, and Bromine in Electronic and Electrical Products – X-ray Fluorescence Spectroscopy (XRF) Method." Among them, the first standard was developed by the Shenzhen Inspection and Quarantine Bureau, while the second was also co-authored by the same organization. A panel of 13 experts from institutions such as the Ministry of Industry and Information Technology, the National Certification and Accreditation Administration, and Sun Yat-sen University conducted a thorough and detailed review of these standards. The expert group concluded that these four national standards fill critical gaps in China’s regulatory framework and are aligned with international best practices. With the EU RoHS Directive now fully implemented, it is crucial to finalize these national standards quickly. This will help accelerate the alignment of China's standardization efforts with global norms and overcome technical trade barriers imposed by the EU and other developed countries on electronic equipment. Experts emphasized that the development of these four standards will promote consistency and standardization in testing for hazardous substances, encourage the substitution of harmful materials, drive industrial restructuring, and support compliance with two key EU environmental directives. This progress is vital for Chinese enterprises to overcome technical trade barriers and enhance the export of their mechanical and electrical products. In addition, China’s "Measures for the Administration of Pollution Control of Electronic Information Products," released on February 28, 2006, will take effect on March 1, 2007. As an essential technical foundation for this policy, these standards will play a significant role in ensuring its successful implementation next year.
