IEC 62321 發(fā)布2013版本
IEC 62321 released 2013 version

        IEC 62321-1、-2、-3-1、-3-2、-4和-5的2013版已通過最終國際標(biāo)準(zhǔn)版草案(FDIS) 階段，目前已正式公布。有關(guān)電子產(chǎn)品中特定有害物質(zhì)測定的標(biāo)準(zhǔn)- IEC 62321，概述了電子產(chǎn)品的測試方法，以確定產(chǎn)品中的有害化學(xué)物質(zhì)濃度低于歐盟有害物質(zhì)限制指令（RoHS）法律中制定的有害化學(xué)物質(zhì)濃度。如同以往，2008版的IEC 62321標(biāo)準(zhǔn)也經(jīng)過了一段維護(hù)周期，現(xiàn)今再將最佳的操作和先進(jìn)的技術(shù)引入測試程序，以確保實驗的一致性和可靠度，滿足標(biāo)準(zhǔn)的制定。

IEC 62321-1 , -2,-3-1 , -3-2, -4 and -5 of the 2013 version has passed the final draft international standard (FDIS) stage, has been officially announced. The standard to measure the specific hazardous substances in electrical and electronic products - IEC 62321, outlined the test method of electronic products, to determine the concentrations of harmful chemicals in products is lower than the limits of EU-RoHS. As ever, the 2008 edition of the IEC 62321 has undergone a period of maintenance cycle, now the best operation and the advanced technology were introduced in order to ensure the consistency and reliability of the experiment, to meet the standards.

Scope
62321-1        簡介和概述
Introduction and overview
62321-2        樣品的拆卸、拆解和機(jī)械拆分
Disassembly, disjointment and mechanical sample preparation
62321-3-1        使用X射線熒光光譜儀對電子產(chǎn)品中的鉛、汞、鎘、總鉻和總溴進(jìn)行篩選
Screening – Lead, mercury, cadmium, total chromium and total bromine by X-ray fluorescence spectrometry
62321-3-2        使用C-IC對聚合物和電子產(chǎn)品中的總溴進(jìn)行篩選
Screening–Total bromine in polymers and electronics by Combustion–Ion Chromatography
62321-4        使用CV-AAS、CV-AFS、ICP-OES和ICP-MS測定聚合物、金屬和電子材料中的汞
Mercury in polymers, metals and electronics by CV-AAS, CV-AFS, ICP-OES and ICP-MS
62321-5        使用AAS、AFS、ICP-OES和ICP-MS確定聚合物和電子材料中的鎘、鉛和鉻，以及金屬中的鎘和鉛
Cadmium, lead and chromium in polymers and electronics and cadmium and lead in metals by AAS, AFS, ICP-OES and ICP-MS

        2013版的最主要變化在于將文件拆分成一系列標(biāo)準(zhǔn)，以利標(biāo)準(zhǔn)維護(hù)，同時導(dǎo)入新的測試方法或儀器，例如燃燒- 離子層析儀(C-IC) 和冷蒸汽原子熒光光譜儀(CV-AFS)。燃燒- 離子層析儀(C-IC)用來測試總溴，冷蒸汽原子熒光光譜儀(CV-AFS)用來測試汞含量。
  The main change of the 2013 version is that the file is split into a series of standards to facilitate standard maintenance, while import new test methods or equipments, such as Combustion - Ion Chromatography (C-IC) and cold vapor atomic fluorescence spectrometry (CV-AFS).Combustion–Ion Chromatography (C - IC) is used to test the total bromine, cold vapor atomic fluorescence spectrometer (CV - AFS) is used to test the mercury.

       在完成上述系列標(biāo)準(zhǔn)之后，目前還有另外三份標(biāo)準(zhǔn)正處于不同草案編制階段: PBB/PBDE (IEC 62321-6)、六價鉻(IEC 62321-7-1和-2)的測試方法。
After completing the above series of standards, other threecriterias are in different developing stages: the test methods of PBB / PBDE (IEC 62321-6), hexavalent chromium (IEC 62321-7-1and -2).
這些標(biāo)準(zhǔn)預(yù)計公布日期如下:
These standards are expected to announce as following dates:
2014年2月- IEC 62321-6
2014年4月- IEC 62321-7-1
2014年11月- IEC 62321-7-2
