DETERMINATION OF CERTAIN SUBSTANCES IN ELECTROTECHNICAL PRODUCTS Part 4 : Mercury in polymers, metals and electronics by CV-AAS, CV-AFS, ICP-OES and ICP-MS 1 概述 This standard specifies the determination of the levels of mercury (Hg) contained in electrotechnical products. These materials are polymers, metals and electronics (e.g. printed wiring boards, cold cathode fluorescent lamps, mercury switches). Batteries containing Hg should 1 be handled as described in [1] . The interlaboratory study has only evaluated these test methods for plastics, other matrices were not covered. 这个标准规定了电子电气产品中Hg 含量的测定。这些材料是聚合物，金属和电子产品 （例 1 如：印刷纸，冷阴极荧光灯， 银开关）。含有 Hg 的电池应该按【1】 中的描述处理。多 个是实验室仅仅评估了对塑料的测试方法，并没有覆盖其他材料。 This standard refers to the sample as the object to be processed and measured. What the sample is or how to get to the sample is defined by the entity carrying out the tests. Further guidance on obtaining representative samples from finished electronic products to be tested for levels of regulated substances may be found in IEC 62321-2. It is noted that the selection and/or determination of the sample may affect the interpretation of the test results. 本标准指的是样品的处理和测试。样品或获得的样品被定义为测试的实体。在IEC 62321 2 中可以找到，进一步从限制含量的电子产品成品上获得有代表性待测样品。值得注意的是选 择和/或测定的样品可能会影响测试结果的解释。 This standard describes the use of four methods, namely CV-AAS (cold vapour atomic absorption spectrometry), CV-AFS (cold vapour atomic fluorescence spectrometry) ICP-OES (inductively coupled plasma optical emission spectrometry), and ICP-MS (inductively coupled plasma mass spectrometry) as well as several procedures for preparing the sample solution from which the most appropriate method of analy
