16 Lead in lead-bronze bearing shells and bulbs
17 Lead in linear incandescent lamps with silicate coated tubes
18 Lead halide as radiant agent in High Intensity Discharge (HID) lamps used for professional reprography applications
19 Lead as activator in the fluorescent powder (1% lead by weight or less) of discharge lamps when used as sun tanning lamps containing phosphors such as BSP (BaSi2O5:Pb) as well as when used as specially lamps for diazo-printing reprography, lithography, insect traps, photochemical and curing processes containing phosphors such as SMS ((Sr,Ba)2MgSi2O7:Pb)
20 Lead with PbBiSn-Hg and PbInSn-Hg in specific compositions as main amalgam and with PbSn-Hg as auxiliary amalgam in very compact Energy Saving Lamps (ESL)
21 Lead oxide in glass used for bonding front and rear substrates of flat fluorescent lamps used for Liquid Crystal Displays (LCD)
22 Lead and cadmium in printing inks for the application of enamels on borosilicate glass.
23 Lead as impurity in RIG (rare earth iron gamet) Faraday rotators used for fibre optic communication systems.
24 Lead in finishes of fine pitch components other than connectors with a pitch of 0.65mm or less with NiFe lead frames and lead in finishes of fine pitch components other than connectors with a pitch of 0.65mm or less with coppler lead frames.
25 Lead in solders for the soldering to machined through hole discoidal and planar array ceramic multilayer capacitors.
26 Lead oxide in plasma display panels (PDP) and surface conduction electron emitter displays (SED) used in structural elements, notably in the front and rare glass dielectric layer, the bus electrode, the black stripe, the address electrode, the barrier ribs, the seal frit and frit ring as well as in print pastes.
27 Lead oxide in the glass envelope of Black Light Blue (BLB) lamps.
28 Lead alloys as solder for transducers used in high-powered (designated to operate for several hours at acoustic power levels of 125 dB SPL and above) loudspeakers.
29 Hexavalent chromium in corrosion preventive coatings of unpainted metal sheetings and fasterners used for corrosion protection and Electromagnetic Interference Shielding in equipment falling under category three of Directive 2002/96/EC (IT and telecommunications equipment). Exemption granted until 1 July 2007.
30 Lead bound in crystal glass as defined in Annex I (Category 1,2,3 and 4) of Council Directive 69/493/EEC
2009年6月11日,歐盟OJ刊登了2009/443/EC,新增了6項RoHS指令的豁免,分別如下:
33. Lead insolders for the soldering of thin copper wires of 100 μm diameter andless in power transformers. 電力變壓器中直徑100微米及以下細銅線所用焊料中的鉛
34. Lead in cermet-based trimmer potentiometer elements. 金屬陶瓷質的微調電位計中的鉛
35. Cadmium in photoresistors for optocouplers applied in professionalaudio equipment until 31 December 2009.2009年12月31日前專業音頻設備的光耦合器中使用的光敏電阻的鎘
36. Mercury used asa cathode sputtering inhibitor in DC plasma displays with a content upto 30 mg per display until 1 July 2010. 2010年7月1日前直流等離子顯示器中陰極濺射抑制劑中的汞,其含量不得超過30毫克/顯示器
37. Lead in the plating layer of high voltage diodes on the basis of a zinc borate glass body. 以硼酸鋅玻璃體為基礎的高壓二極管的電鍍層的鉛
38. Cadmium and cadmium oxide in thick film pastes used on aluminium bonded beryllium oxide. 用氧化鈹連接鋁制成的厚膜漿料中鎘和氧化鎘
此前,在6月5日,歐盟還刊登了2009/428/EC,從2011年1月1日起,將原豁免的第22點“光纖通訊系統稀土鐵石榴石法拉第旋轉器中作為雜質的鉛”從豁免列表中移除。
其實rohs一直都有在增加豁免條例。
常用的RoHS檢測方法
1、陰離子:英藍技術離子色譜法
采用氧彈燃燒、英藍技術前處理之后,直接進入離子色譜進行分析
2、陽離子及其價態:
采用英藍陽離子色譜法、離子選擇電極法、原子吸收法均可檢測
確定陽離子元素價態可采用伏安極譜法進行分析
