　　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，欧盟OJ刊登了2009/443/EC，新增了6项RoHS指令的豁免，分别如下：

　　33. Lead insolders for the soldering of thin copper wires of 100 μm diameter andless in power transformers. 电力变压器中直径100微米及以下细铜线所用焊料中的铅

　　34. Lead in cermet-based trimmer potentiometer elements. 金属陶瓷质的微调电位计中的铅

　　35. Cadmium in photoresistors for optocouplers applied in professionalaudio equipment until 31 December 2009.2009年12月31日前专业音频设备的光耦合器中使用的光敏电阻的镉

　　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日前直流等离子显示器中阴极溅射抑制剂中的汞，其含量不得超过30毫克/显示器

　　37. Lead in the plating layer of high voltage diodes on the basis of a zinc borate glass body. 以硼酸锌玻璃体为基础的高压二极管的电镀层的铅

　　38. Cadmium and cadmium oxide in thick film pastes used on aluminium bonded beryllium oxide. 用氧化铍连接铝制成的厚膜浆料中镉和氧化镉

　　此前，在6月5日，欧盟还刊登了2009/428/EC，从2011年1月1日起，将原豁免的第22点“光纤通讯系统稀土铁石榴石法拉第旋转器中作为杂质的铅”从豁免列表中移除。

　　其实rohs一直都有在增加豁免条例。

常用的RoHS检测方法

　　1、阴离子：英蓝技术离子色谱法

　　采用氧弹燃烧、英蓝技术前处理之后，直接进入离子色谱进行分析

　　2、阳离子及其价态：

　　采用英蓝阳离子色谱法、离子选择电极法、原子吸收法均可检测

　　确定阳离子元素价态可采用伏安极谱法进行分析
