At this time, we have sent personnel to attend international IEC/TC111 activities. Under coordination by the Standard Administration of China, a technical committee is formed in corresponding to the TC111 WG3 (China WG3 working group). The task of forming a working group for test procedures of national standards for the density of toxic substances of electronic and electrical products is completed. The formation of a working group for industry standards for the prevention of pollution caused by electronic information products had been completed in October, 2004. This working group starts on the formation of standards for limits, test standards, leadless soldering standards, and certification and labeling standards.
