One substance, lead chromate, will be included in the Candidate List without involvement of the Member State Committee, because ECHA received no comments on its hazardous properties in the preceding public consultation.

虽然没有委员会的各成员国的参与，铅，铬等中金属物质也将被列入候选名单，因为欧洲化学品管理局收到了公共谘询部门关于重金属物质的危险性报告。

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.

目前，我们已经派员积极参与了国际 IEC/TC111的活动，在国标委的统一协调下，牵头组织了中国对应 TC111的 WG3的一个技术委员会（目前暂称为中国 WG3工作组）；组建电子电气产品有害物质浓度检测程序国家标准工作组的工作已经完毕；电子信息产品污染控制行业标准工作组已经在2004年10月组建完成，已经开始了制定电子信息产品有毒有害物质的限量标准、检测标准、无铅焊接标准、认证与标识标准的工作

In this work, GC-MS, ICP-OES, UV-Visible Spectrophotometry were employed to determine the trace concentrations of the above six hazardous substances, and a standard method system for screening primarily, extraction, qualitative and quantitative analyses of the six substances was established and their factors were analyzed. By evaluating the relative standard deviation, recovery, repeatability, limit of detection, linear relation etc., the optimum parameters were given and thus the precision of analysis was equal to or higher than the IEC 62321 standard, meeting the requirement of RoHS.

针对中国电子电气业在遵守RoHS符合性实践中存在的诸多问题，本文采用GC-MS，ICP-OES，UV-Visible分光光度法等，对我国南方和香港地区各类电子电气产品中六种有害物质进行痕量分析，建立了一套标准的六种有害物质初步筛选、萃取、定性、定量分析方法，并对此方法体系的影响因素进行分析，对其相对标准偏差、回复率、再现率、检出限、线性关系等进行评估，得出了优化测试参数，在此条件下其检测的精密度达到或高于国际IEC 62321标准，满足RoHS测试要求。
